LXK-80,100,120 zero-sequence current transformer at 35kV and below.
AC 50Hz line for the power system as well as the high voltage three-phase alternator ,the motor's zero sequence over-current protection,and applies only to indoor .
The outer diameter of the output cable is not greater than 120mm.
The zero sequence current transformer for the cable type,it is only necessary to examine the insulating properties of the secondary coil,secondary coil can withstand the power frequency withstand voltage 3kV.
