TRANSFORMER . . .
Step down Transformer are used to convert high voltage primary supply to low voltage secondary output.
STANDARDS: IEC 76 BS 171 ANSI C57 12, VDE 0537
FREQUENCY: 50Hz, on request 60Hz
PRIMARY VOLTAGE : Above 11KV up to 36KV
SECONDERY VOLTAGE: 400-433V other values may be offered.
Double low voltages with 7 LV bushings can be offered with full
rating. On both voltages or with reduce rating (75) on lowest
voltage.

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.
EQUIPMENT :
LBS (F&G, Hausmann, Germany)
VCB (ABB, Italy, /Siemens, Germany
CT PT (Siemens, Germany)
IDMT RELAY (Omron japan/ Mikro , Malaysia.
Amp & Volt meter. (Risesun/Taiwan)
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.
ATS (AUTO TRANSFER SWITCH) for common and flats emergency line….
