The LZZ7-36 current transformer is a 36kV indoor single-phase epoxy resin casting and fully enclosed support type device. It is designed for accurate metering of current and electric energy as well as protective relaying in medium-voltage electrical systems operating at rated frequencies of 50Hz or 60Hz.
With a rated insulation level suitable for equipment voltages up to 36kV (and up to 40.5kV in some cases), the transformer complies with IEC 60044-1 and IEC 61869-1 & 2 standards. It is ideal for indoor installation and offers reliable performance in various power system applications.
