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. |
