电能表属于依法管理,强制执行检定的工作计量器具。影响其示值误差的原因主要有以下几个方面: 一.100％Ib(满载)示值误差我们知道,造成电能表转盘转动的主要原因是由于电流流经电流线圈时产生的工作磁通及其感应电势引起的。所以,当电流线圈出现问题后,将会直接造成电能表的示值误差超值。电能表在满载情况下出现的示值误差主要在于电流线圈是否完好。
Meter belongs to the management of law, the implementation of the test of the work of measuring instruments. The main reasons that affect the indication error are as follows: I. 100% Ib (full load) indication error We know that the main reason for the electric meter turntable rotation is due to the current flowing through the current coil when the work of the magnetic flux and Its induced potential caused. Therefore, when the current coil problems, it will directly result in indication error value of the energy meter. Ammeter appears under full load indication error is mainly the current coil is intact.
