Fluctuations in the voltage is a constant feature of Electricity supply we get. Constant fluctuation of a voltage leads to frequent breakdown and higher rejection in end product. We know that 90% of industrial load is of motor. It draws high current at high & low voltage. This higher current produce higher losses in electrical motors. These losses in motor increase the losses in Cables, Switches, Transformers and other associated equipments.
This higher current effects the electrical motor (particularly smaller capacity motor up to 7.5 H.P)in 3 ways
With the installation of the stabilizer & maintains 390/400 volt, the motor will operate smoothly drawing 15-20% lesser current & correspondingly the relay setting can be reduced by 15-20%.
The Buck/Boost and Regulator Transformer winding are built from paper covered electrolytic copper strip or enamelled copper conductor (Dried in oven). The core is built of high grade cold rolled grain oriented silicon lamination (CRGO) to minimise iron losses. All components of equipment mounted on a framework of M.S. housing are fitted with cooling pips to provide natural cooling.
We provide a vertical Rolling Contact types voltage regulator with having sections and paper covered copper strip and fitted with carbon roller assembly which offer higher reliability than ordinary carbon brushes. It is also built with high quality meter switches and indicators.
It is designed for 30-35 Degree Centigrade above ambient suitable for any kind of ambient temperature condition. Oil which is used as a coolant is of IS: 335 standards being used & it is properly filtered before topping.
Automatic Servo Stabilizer are available in wide range and various models. The standard three phase models are suitable for balanced and unbalanced supply and loads. The standard model confirm the following specifications are as follow:
| Input Voltage | 300-460V 320-460V 340-460V 360-460V. |
| Efficiency | Better than 99%. |
| Output Voltage | 400V, +/- 1%, Phase, 50HZ. |
| Ambient | 0-35°C max relative humidity upto 90% |
| Environment | Designed for Indoor tropical use |
| Wave from distortion | Virtually Nil. |
| Duty Cycle | 100% Continous. |
| Correction Rate | 8-10V/Sec. (Upto-500KVA). |
| Mounting | On Uni-directional wheels. |
| Cooling | Air Cooled/Natural Oil Cooled. |
NOTE: Different Non-Standard input & output ranges are also available against specific requirement.
| Bharti make roller type Regulator | Conventional make with carbon brush Regulator |
|---|---|
| Suitable for 100% continuous duty cycle | Suitable only for partial load 50-60% |
| Power consumption is 0.5 to 1.5% depending upon the model & input voltage variation. | Power consumption is 2-7% |
| Life at full load is 15-20 years | Max. life is 3-5 years at full load |
| Negligible losses at full Buck/Boost conditions. | Max-losses in full Buck/Boost condition |
| 5 years unconditional guarantee in india. | Normal guarantee/warrantee for one year |
| As losses are less, heat generated is less. The size of stabilizer is very compact. Quantity of oil is less. | Heat generated is more. Size is bulky. Quantity of oil is more. |
1. In residential area, we usually face unbalanced input voltage, in that case Automatic Voltage Controller is used to Overcomethis problem. This unbalanced voltage usually causes the failure or damage of motors, machines, electronic items used in houses, tubes, bulbs, fans etc. If you find input voltage is above 230 Volt single phase/400Volt three phase even for few hours a days, then you definitely require a stabilizer.
2. Industries which have installed OLTC with transformer also require Stabilizer because with help of Stabilizer, we don't have to change the tapping of OLTC frequently. However range of Stabilizer can be kept low where OLTC is installed
