VT and CVT are besically use the same fundamental physics for measure the voltage at sedondary as according to its primery..but the besic diff. Is VT usually use for measurement to voltage for protection ckts as well for metering purpose, CVT also can be use for the same purpose but additional advantage with CVT is it can be use in communication purpose as it does have the capacitors as a fliter who can diff. The communication signals and protection signals or you can say tele protection also the purpose depands on the classes of VT and CVT as according to requirement of protection and communication like over voltage pro. Distance pro. Or metering as per requirement

how to find out cable size if load is 2800 watts, 230 volts AC supply and load distance is 1800 meters
True or false question. 1.The fuse provide phase and neutral 2.power loss in electrical circuit can take place in (resistance or inductance or capacitance). 3.two phase system each phase has separated by a phase difference of (90 or 180 or 270 or 45). 4.3 phase balanced star connected load neutral current shall be (line current or phase current or zero or unity)
