Creeping is the considerable problem in the analog energy meter because the meter disk rotates even no electrical current flowing through current coil(on no load condition) and also slightly higher speed under lightly loaded condition.
The main reason for creeping is over-compensation the aluminium disk to over come the static friction of disk and another reason is over voltage across the shunt magnet.Due to this creeping consumers suffers from high tariff. In order to prevent this creeping phenomenon two diametrically opposite holes are drilled on the aluminium disk,the disk will come to rest with one of the holes under the edge of a pole of the shunt magnet the rotation being thus limited to a maximum of half a revolution.
