Is it possible to protect 3phase overload and earth fault of the 3phase system using two CT's.
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)

A ray hit a smooth regular surface at an angle of 20 from the normal. Calculate : 1. The angle btw the incident and reflection ray. 2. The angle of deviation.
While testing a ZCT what parameters have to check or measure?
when ac current flows thru d coil of a contactr,it energizes,magnetic field attracts d contact of the coil...nw wont dt ac current in d contct induce current back on to d coil thru mutual inductance leading to high currnt in d coil
