you mean now that the kvarh meter has adesplacment angle ( -90 ) for current coil lagging the voltage in voltage coil .
and the kwh meter has adesplacment angle ( o) ie in phase ?
And nothing to do with the internal link
And the settings are but by special equipment at the factory to adjust the...
Thank you my friend
Do you mean that interconnect such as Star or Delta connections are Determined the work of the meter
If it internalconnected as a star for voltage coils it records kWh and if internalconnected is delta it records kilo varh ?
Thank you dear
I understand the triangle of power components.
But my question for the analog meter with a dynamic disk. Do the same meter measures kw and kvar or there is a difference in internal structure and theory of work between each meter.
ie how can i know the meter if it is watt hour...
Hello
Please, i want to ask the following question and give me the answer as much as possible
What is the difference between the watt hour meter and Var hour meter in terms of internal connection and work theory .
thanks
