In an ACB shunt trip coil and undervoltage coil operated normally( breaker open and charged). But closing coil not operating untill manually discharge and recharging. Any help.
PPIL,
1269If I have Energy Meter Ratio as 100:5 & Also I have CT Ratio as 50:5 then what will be my multiplying Factor(M.F.)
1533i am completed diploma in ece,and working in ht and lt lines.so is elligible diploma in ece for get electrical C Licence?plse give ur opinion?
1341if main CT is of ratio 50/5, and meter CT is -/5 what will be overall multiplying factor of meter.PT is 11000/110 .
BSNL,

1182How to calculate voltage drop in copper and aluminium cable? I have laid 240Sq.mm Aluminium cable for the length of 600 Mtrs in 1 Mtrs underground. Normal load is 150A. Transformer is 630KVA, 6.KV/433V. But, I am getting only 395 Volts when load. How to calculate voltage drop and what is the permissible voltge drop for this circuit?

y we use neutral,all r told its used to for closed path..k its a just used to closed path,in a transmission line y we put same conductor used n both phase and neutral..if we use less than phase conductor in neutral mean we ll reduce cost its right r wrong..if we use mean any problem occur in transmission line..
