Current transformers General Current transformers are used extensively for measuring current and monitoring the operation of the power networks. LMZK-10 is a bushing type current transformer. Its outer casing is made with ABS engineering plastic and integrated with epoxy resin filling. This current transformer has main features as good isolative performance, smart appearance and simple assembly etc; especially its bracket opening design can realize direct mounting on power cable without any alteration to cable. Options with different ratios are available for different power network operation requirements.
