A.C Drive
A.C Drive
An AC drive is a device used to control the speed of an electrical motor in order to:
- Enhance process control
- Reduce energy usage and generate energy efficiently
- Decrease mechanical stress on motor control applications
- Optimize the operation of various applications relying on electric motors.
Surge Arrester
Surge Arrester – Is a device to protect electrical equipment from over-voltage transients caused by external (lightning) or internal (switching) events.
Capacitor Bank
Capacitor Bank – It is used to control the level of the voltage supplied to the customer by reducing or eliminating the voltage drop in the system caused by inductive reactive loads.
R.V.T
R.V.T – Residual voltage transformer is used to detect unbalanced voltage in three phase system and to supply voltage to directional earth fault relay.
Shunt Reactors
Shunt Reactors – It is used in extra high-voltage substation to neutralize inductive reactance in long Extra high voltage transmission lines.
E.L.C.B
E.L.C.B – Earth leakage circuit breaker
A safety device used in Electrical installations with high earth impedandce to prevent shock.
Breather
Breather – It is control the level of moisture, entering electrical equipment during the change in volume of the cooling medium and/or airspace caused by temperature increasing.
Silica gel
Silica gel – Silica gel is uses in breather transformers for controlling the level of moisture and prevents it from entering the equipment.
Transformer Oil
Two types of oil uses in Transformer are below :
- Naptha based transformer insulation oil
- Paraphin based transformer insulation oil
