When current transformers are operated open circuited, extremely high voltages can be generated with resultant damage to equipment and personnel.

Before removing a load such as a meter or relay, the CT should be short circuited using a shorting block. The ungrounded secondary of a voltage transformer and the line side of the power supply should be fused before connecting to a device such as a meter or relay. ShortingBlocks.com manufactures several models of shorting and test blocks.
