LZZBJ9-10 CT Construction

The product features a leg-type, fully enclosed structure with a ring core. Both the primary and secondary windings are insulated with cast resin, providing enhanced insulation that ensures reliable operation under humid and polluted conditions.

The outlet markings include:

When the primary current flows from P1 to P2, the secondary current flows from S1 to S2 through the external return circuit. If the secondary return circuit is open while the primary current is flowing, a high voltage will be generated, posing a safety risk.

LZZBJ9-10 CT Technical Parameters

The technical parameters of the LZZBJ9-10 current transformer are designed to meet the standard requirements of power grids and electrical systems. These parameters ensure reliable performance for current measurement, power metering, and relay protection in 10kV AC power systems with a rated frequency of 50Hz.
