HT SWITCHGEAR

High voltage switchgear is any switchgear used to connect or disconnect a part of a high-voltage power system. This
equipment is essential for the protection and safe operation, without interruption, of a high voltage power system, and is important because it is directly linked to the quality of the electricity supply.

LT SWITCHGEAR

A Distribution board (also known as panel board, breaker panel, or electric panel) is a component of an electricity supply system that divides an electrical power feed into subsidiary circuits while providing a protective fuse or circuit breaker for each circuit in a common enclosure.

 

 

 

 

 

 

 

 

 

PFI PLANT

Microprocessor-based Power Factor Correction relay controlled the switching of Parallel connected Power capacitor which rated 2.5kVAr, 5kVAr,7.5kVAr,10kVAr,12.5KVAr, 15kVAr,20kVAr, 25kVAr, 50kVAr…and more, corresponding magnetic Contactor for suitable stepping of the capacitor Bank, sometimes also used detuned reactor with series in capacitor for harmonic filtrations.
