The Single Phase energy meter records the single phase power as,
P=V*I*PF*Hours.
It is also called Watt-Hour Meter.Bcaz its record the
consumption of power in terms of hourly basis.
The Speed or Torque of the Disc(In case Of Non-electronic
meter),is equal to power in watts.
Torque=Power.Torque is directly proportional to power.

in cvt,there are two windings,1a,1n and 2a,2n.in my one project i use only one winding i.e.1a,1n. the other winding is not in use, so i connect it in open delta and want to close it by ibsertibg thermal resistor. the output of cvt is 132kv/115/sqrt3. plesae tell me exact value of resistor, so i may close it to avoid the resonance phenomenin. send me answer on this email adress please. aetcon-po@aetcon.com
