Tricky but Easy Electrical Engineering!
Creeping in energy meters is phenomena due to which the disc of energy meter rotates even in absence of any load current in the current coil (CC) and only pressure coil (PC) is energized. The necessary condition for creeping is that PC must be energized. This is required as the friction compensating device is voltage … Read more
There are basically three types of energy meters: Electromechanical Energy Meter: The electromechanical induction meter operates by counting the revolutions of a non-magnetic, but electrically conductive, metal disc which is made to rotate at a speed proportional to the power passing through the meter. The number of revolutions is thus proportional to the energy usage. … Read more
