.SplitCore Current Transformers are designed for assembly to an existing electrical installation no needto dismantle the primary busbar or cables.

The KCT range of split core current transformers have been specifically designed to be small CT and easy to open and yet
maintain the accuracy required for kwh meters. The benefit of a split core current transformer is that it can be placed
into position easily and without disturbing or disconnecting the main cables it is monitoring.

The KCT range of split core current transformers have been specifically designed to be small CT and easy to open and yet maintain the accuracy required for kwh meters. The benefit of a split core current transformer is that it can be placed into position easily and without disturbing or disconnecting the main cables it is monitoring. The KCT range of current transformers has two insulated terminal covers for connecting the S1 and S2 cables which lock down over the terminal screws fully insulating the connections. This makes it ideal to use Autometers cable hamesses which are colour coded and individually numbered on each conductor ensuring simple and easy connection from the current transformer to the electricity meter.

HK Series split core current transformer is HEYI Electrical current transformer manufacturer newly developed products and the
split core CT are designed in particular for esay installation, the quick release button makes the ct the most convenient to fit around
cables without cutting off the circuitry. HK current transformer has advantages of bigger capacity and bigger mounting hole size,
could be used in more power applications.
