The LMZS-0.66 fully enclosed transformer measuring device is a new type of fully enclosed measuring device specifically designed for measuring the low voltage end of 10kV power transformers installed indoors and outdoors.
The internal transformer of the device uses a super microcrystalline alloy iron core, a single turn through core busbar structure, an SMC pressure formed shell, and epoxy resin fully cast insulation. The three-phase current transformer is cast in one go, which has the characteristics of small volume, high accuracy level, and strong overall sealing.
This device is directly installed on the low-voltage output terminal of the transformer, using tempered glass and a casting body to be installed in a closed manner, that is, the output terminal is completely closed, and the secondary wiring can be directly observed from the outside. Has good anti-theft performance.
