Answer / sadineni sreedhar
yes secondary voltage of ct greater then primary but the secondary terminals should be looped that's why the secondary voltage is zero when we are open the secondary terminals(at the charging condition) then voltage will increase and it may damages/ blasts the ct because of ct secondary cannot insulated for that much of high voltages

Determine the minimum cable size for a 28A single phase final sub circuit originating from the distribution board supplied by three phase submain. The route length of the final sub circuit is 54 m. Assume 1% voltage drop in the consumer's mains. Submain specification: Cable: 50mm2 4 core V75 copper; Route length 42m; Maximum demand 135A per phase
What is the name of the winding from which the supply is taken for load connections?
power is the product of voltage and current.so we can measure the value of power just by using ammeter and voltmeter.......then why do we use a wattmeter?
