Answer / viswanathan karthikeyan

Basic Concept :
Incomer
Outgoings
Main Incomer -Cable or OHL LINE -PLEASE CONSIDER
STEPDOWN AUTO TRANSFORMER-220/132kV
NEXT AGAIN STEPDOEN TRANSFORMER-132/33Kv
stepdown Transformer-33/0.415kV

MAIN INCOMER NEED CIRCUIT BREAKER
220KV GIS
132KV GIS
33KV GIS

IF OHL LINE MEANS
gantry
WAVE TRAP
SURGE ARRESTER
COUPLING CAPACITOR
AAAC CONDUCTORS,TOWERS ETC(d0,d2,d6,d9,dt)

CABLE MEANS
220KV CABLE

CONTROL AND REALY PANELS
220,132,33 FOR RELAY AND PROTECTION PANEL

LV,HV,EHV CABLES
EARTHING MATERIALS
EARTHING AUXILLARY TRANSFORMER]
NEUTRAL EARTHING TRANSFORMER

TELECOMMUNICATION PANEL
SCS SYSTEM
BATTERY AND BATTERY CHARGES
EOT CRANE
PUMPROOM
LIGHTING AND LIGHTNING PROTECTION
EARTHING MATERIALS ETC

SO MANY ITEMS REQUIRED

I AM DOING THIS TYPE OF PROJECT
IF ANY DOUBT ,PLEASE SEND MAIL TO ME-vkn.1980@gmail.com

Answer / loruenser

Mind quality connectors, as a very vital part!

In Air circuit breaker LSIG protection unit is used. Without fault in cables (2 runs 3Cx150Sq.mm Copper, 1Kv grade, XPLE armored cable IR value is more than 550Mohm @ 500V Megger) and load section Long time Overcurrent protection is triggers and trips the unit. We changed LSIG protection with new factory tested unit. Even then fault is persisting. Please suggest the possible causes
