该电表为磁电系和电磁系两种，适用于安装在各类自动控制系统和配电系统的显示面板和大型关板上指示相关电参数，如：交直流电流电压、功率因数、功率、频率、展开电压和过载电流等。产品性能符合GB7676-98标准。
The meters may be of movingcoil
type and moving-iron type,when mounted
in all kinds of displaying panels and
large size switchboards of Automation
Systems and Distribution Systems,suitable
for indicating the rele vant electrical
parameters,such as AC/DC currents and
voltages,cosφ,W,Var,Hz,etc.The specifications
are in agreement with GB7676-98. |
