In short. Reddy Generators sells, rents, services and modernises diesel generators for customers in Nizamabad and Kamareddy districts, including control-panel upgrades of the kind we carried out for TSGENCO at Nizamsagar. We plan each job from our Hyderabad base — Kamareddy is about 110–117 km and Nizamabad about 175 km up NH 44 — and confirm timing when you call. This page focuses on the two things that matter most in this agricultural belt: starting big motors on a generator, and getting more life out of older sets.
Who this page is for: Turmeric processors and traders, rice-mill owners, irrigation and water-supply engineers, hospital and college facility managers, and anyone in Nizamabad, Armoor, Bodhan, Kamareddy or Nizamsagar who runs motor-heavy loads or an older generator that needs modernising.
Key facts
- Route: NH 44 runs from Hyderabad past Kamareddy and bypasses Nizamabad; NH 63 passes through Nizamabad and crosses NH 44 at Armoor on its way east towards Chhattisgarh.
- Power distribution: TGNPDCL serves Nizamabad and Kamareddy districts.
- Turmeric: Nizamabad district has over half of Telangana’s turmeric area; the National Turmeric Board is headquartered in Nizamabad, and a geographical-indication application has been filed for Armoor turmeric.
- Rice: Nizamabad is among the largest rice-producing districts in the state, with many rice mills.
- Water: the Nizam Sagar dam on the Manjira (built 1923–1931, Kamareddy district) has a 2 × 5 MW power house run by TSGENCO; the Sriram Sagar project on the Godavari at Pochampad irrigates several northern districts.
- Heat: summer maximums are often above 42 °C and heatwave days pass 45 °C.
- Confirmed local work: DG control-panel modernisation for TSGENCO at Nizamsagar.
Our work at Nizamsagar
We modernised the DG control panel for TSGENCO at Nizamsagar, replacing ageing control equipment so that the generator could again be started, monitored and protected reliably. The work is described on our project page, DG control-panel modernisation for TSGENCO at Nizamsagar. The same approach — keep the sound engine and alternator, renew the controls and protection — is often the most economical answer for older sets at rice mills, colleges and pumping stations in the district. Across Telangana we also maintain DG sets, AVRs and fire-fighting engines at nearly 50 TS TRANSCO substations (see that work).
Local conditions and generator decisions
| Local condition | What it means for the generator | Decision |
|---|---|---|
| Processing loads dominated by motors: polishing drums, boilers’ feed pumps, elevators, hullers, borewell and lift pumps | Starting current, not running load, often decides the set size | Size for the largest motor start; choose soft starters or star-delta where possible (worked example below). |
| Seasonal peaks — turmeric boiling, drying and polishing after harvest; rice milling after the paddy seasons | Sets idle for months and then run long days | A pre-season check and loaded run; batteries and fuel checked before the season; rental for peak months. |
| Summer maximums around 45–47 °C | Output derating and high-temperature trips | Rate at site ambient; keep radiator air paths clear. See summer precautions. |
| Turmeric dust and rice husk in the air | Clogged air filters and radiators; fine dust in alternator windings | Locate the set away from polishing and husk areas; shorter cleaning intervals. |
| Many sets 15–25 years old in mills, colleges and public utilities | Obsolete controllers, failed gauges, unreliable auto-start, missing protections | Modernise the control panel, AVR and protection rather than replace a sound engine — after an inspection. |
| Long rural feeders | Phase loss, low voltage; motors burn out on single phasing | Phase-failure relays and an AMF panel; motor protection set correctly on the generator supply. |
Sites in Nizamabad and Kamareddy — typical sets and duty
| Site type | Where | Typical set size | Duty and what matters |
|---|---|---|---|
| Turmeric processing (boiling, drying, polishing, grinding) | Nizamabad, Armoor and surrounding mandals | 30–200 kVA | Seasonal, motor-heavy, dusty; polishing drums and grinders start under load. |
| Rice mill (raw and parboiled) | Across Nizamabad and Kamareddy districts | 82.5–320 kVA | Elevators, hullers, polishers, colour sorters and boiler pumps. See rice and grain. |
| Irrigation, lift and water-supply pumping | Canal and reservoir systems; village and town water supply | 62.5–750 kVA | Large submersible or centrifugal pumps; starting method and cable length matter. See agriculture and irrigation. |
| Power house and dam auxiliaries | Hydro stations and gate operations | 62.5–250 kVA | Emergency supply for gates, drainage, lighting and controls; reliable auto-start after long idle periods. |
| Colleges, university and hospitals | Nizamabad town, Dichpally (Telangana University), Kamareddy | 62.5–500 kVA | Labs, hostels, pumps, operation theatres; quiet acoustic sets. |
| Poultry farms and feed units | Kamareddy area | 30–160 kVA | Ventilation fans, lighting and water; summer outages are critical for birds. |
Typical ranges only; the right size depends on your motors and how they start.
Illustrative case: a turmeric polishing unit with a borewell pump
Illustrative case. A processing unit near Armoor runs an 11 kW polishing drum, a 15 kW submersible pump and about 4 kW of lighting and office load. Running demand is small:
On running load alone, a 50 kVA set would look adequate.
The pump changes the answer. Its full-load current is about 27 A at 415 V. Started direct-on-line it draws about six times that, roughly 164 A, which is a starting demand of 1.732 × 415 × 164 ÷ 1,000 ≈ 118 kVA. A simple screening estimate of the generator’s voltage dip, using an illustrative transient reactance of 0.20, is:
| Set size | Direct-on-line (≈118 kVA) | Soft starter at about 3 × current (≈59 kVA) | Star-delta (≈39 kVA) |
|---|---|---|---|
| 62.5 kVA | about 27 % | about 16 % | about 11 % |
| 82.5 kVA | about 22 % | about 12 % | about 9 % |
| 100 kVA | about 19 % | about 11 % | about 7 % |
| 125 kVA | about 16 % | about 9 % | about 6 % |
If the aim is to keep the dip within roughly 15–20 % so that contactors hold and the polishing drum does not stall, a direct-on-line pump needs a set of around 100–125 kVA — three times the running load. Fitting a soft starter brings the same result on a 62.5–82.5 kVA set, which also runs at a healthier share of its rating (30 kW is 60 % of a 62.5 kVA set’s 50 kW). Starting the pump first, before the drum, helps further. The real figures come from the chosen set’s data sheet and the pump maker’s starting data; our motor starting guide and load-step screening tool show the method.
The wider lesson for Nizamabad: before buying a bigger generator for a motor-heavy unit, price a soft starter. It is often the cheaper fix, and it protects the motor and pump too.
How sales, rental, service and spares work for Nizamabad and Kamareddy
- New sets: CPCB IV+ compliant sets through our supply tie-ups with all major makes, delivered by road from Hyderabad. Have the plinth, access for the crane or hydra, and the cable route ready on delivery day.
- Used and refurbished sets: 15 to 2,000 kVA, all major makes, every one load-bank tested before sale. Refurbished sets carry a six-month warranty (exclusions apply); used as-is sets come with an inspection report. We buy used sets and accept part exchange.
- Rental: from our own fleet for processing peaks, pump trials, events and bridging while a set is overhauled. Book ahead of the season; availability and dispatch are confirmed when you book.
- Service and AMC: breakdown calls seven days a week, 8:30 am to 8:30 pm; travel time from Hyderabad is confirmed on the call. AMC visits are planned — with a pre-season visit for seasonal processors.
- Modernisation: control-panel replacement, AVR and controller work, AMF panels and changeovers, alternator rewinding and overhauls, planned after an inspection so the sound parts of the set are kept.
- Spares: parts for all makes from Hyderabad. Send the engine and alternator nameplate photographs with every parts request.
Getting a seasonal set ready for the processing season
Turmeric and rice processors often run their generators hard for a few months and leave them idle for the rest of the year. Idle time is not rest for a diesel set: batteries discharge, fuel gathers water, seals dry out and rodents find the wiring. Plan the following about a month before the season, and book a service visit early, because every processor in the district wants one at the same time.
- Battery: test it under load; replace if weak. A set that will not crank on the first morning of the season costs a day of production.
- Fuel: drain water and sediment from the tank bottom; if the fuel has stood for many months, have it checked and change the fuel filters. See generator not starting for the fuel-related causes.
- Lubrication and cooling: change the oil if it has passed its time interval even with few hours; check coolant level and condition, hoses and belts.
- Air path: clean the radiator and air filter of last season’s turmeric dust or husk; remove nests and debris from the enclosure.
- Electrical: check the insulation of the alternator windings if the set stood through the monsoon; tighten terminals; confirm the AVR holds voltage on load.
- Loaded run: run the set on the real processing load, or a load bank, for at least half an hour and record kW, voltage, frequency, oil pressure and coolant temperature.
- Motors and starters: confirm that starters, overloads and phase-failure relays work on the generator supply, and that the largest motors start one at a time.
If the season is short and the set is old or too small, renting for the peak months and retiring the old set — or selling it to us — is worth comparing with an overhaul.
Old-set modernisation assessment sheet
Many sets in the district are mechanically sound but let down by their controls. Fill in this sheet and send it with photographs; it tells us whether a panel upgrade, a refurbishment or a replacement makes sense.
| Item | Your entry |
|---|---|
| Set make, kVA, year of manufacture | |
| Running hours (or “meter not working”) | |
| Does it start on the first attempt? Manual or automatic start? | |
| Smoke colour on start and on load (none / black / white / blue) | |
| Oil top-up between services (litres) | |
| Gauges and meters working? Which are not? | |
| Protections working: low oil pressure, high temperature, overspeed, over-current | |
| Voltage steady on load? Any hunting of speed or voltage? | |
| Changeover type today: manual switch / contactor / AMF panel | |
| Largest motor on the set and its starter | |
| Hours per year the set is expected to run in future | |
| Is remote monitoring or alarm messaging wanted? |
| What the sheet shows | Usual direction |
|---|---|
| Engine starts and runs cleanly; controls, meters or protections faulty | Control-panel modernisation, new AVR if voltage is unstable, AMF panel if automatic changeover is wanted. |
| Smoke, oil consumption or low compression as well as control faults | Inspection, then top or major overhaul with the panel upgrade, or a refurbished replacement. |
| Set too small for current motors, or parts no longer obtainable | Replacement, with the old set taken in part exchange. |
Common mistakes
- Buying a generator sized for running load, then finding it cannot start the borewell or lift pump direct-on-line.
- Buying a much bigger set to start one motor, when a soft starter would have solved it for far less.
- Leaving a seasonal processing set untouched for months and discovering a flat battery and stale fuel on the first day of the season.
- Replacing a sound engine because its gauges and auto-start have failed, when a control-panel upgrade would have restored it.
What to send us
Send us the site’s location in Nizamabad or Kamareddy district, the list of motors with their kW ratings and starter types, the running hours you expect in the busy season, photographs of the set’s nameplates, control panel and changeover, the filled modernisation sheet if you have an older set, and whether you want to buy, rent, service or modernise. Use the Service and AMC enquiry, or WhatsApp the details and photographs.
Questions customers in Nizamabad ask
Do you provide generators on rent in Nizamabad?
Yes. We rent sets from our own fleet for turmeric and rice processing peaks, pump trials, events and bridging during overhauls in Nizamabad and Kamareddy. Book before the season; availability and dispatch are confirmed when you book.
What size generator do I need for a borewell or submersible pump?
Size for the pump’s starting current, not its running power. A 15 kW pump started direct-on-line can need a set three times larger than its running load; a soft starter or star-delta starter brings the size down sharply. Send us the pump rating and starter type.
Can you upgrade the control panel of an old generator?
Yes. We carried out DG control-panel modernisation for TSGENCO at Nizamsagar, and we upgrade controllers, protections, AVRs and changeover panels on older sets of all makes after inspecting the engine and alternator.
Do you service generators in Kamareddy, Armoor and Bodhan?
Yes. Our service area covers all of Telangana. Breakdown calls are taken seven days a week, 8:30 am to 8:30 pm, and travel time from Hyderabad is confirmed when you call.
Is it better to repair my old generator or buy a new one?
If the engine starts cleanly and uses little oil, modernising the controls is often the economical choice. If it smokes, uses oil or is too small for your motors, an overhaul or replacement is better. Our assessment sheet helps decide.
Do you sell refurbished generators in Nizamabad?
Yes. Refurbished sets carry a six-month warranty with stated exclusions, and every used or refurbished set is load-bank tested before sale.
