how to calculate the slowness and fastness of energy meter if we have different kw load for example (0.746 kw and meter rev constant 400 and we calculate the 2 rev in 30 sec) please explain the formula thanks
Meter rev constant means rev/ kwh ? Then one rotation =60x60/400 or 9kws . 2 rotations = 18kws.Time taken is 30s. Then the av load is 18/ 30 or 0.6 kw
