The Premier on-line source of CT Shorting Blocks and Fused Terminal blocks for metering and relaying requirements

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.
