Potential Transformer

LMZK4 split core potential transformer is suitable for measurement of primary current, or for protection of electrical equipments such as microcomputer in 10KV and 35KV AC power distribution networks. It is widely used in fully insulated ring network switchgears such as ABB-Safe Ring/Safe Plus...and cable distribution boxes. The transformer can be directly installed at the inlet and outlet of the GIS or AIS cables. The semicircular ring core and secondary windings are vacuum poured by insulated resin. This CT is also used for signal acquisition for RTU or FTU.
