IEEE Revises IEEE C37.20.6-2015 Standard for Ground and Test Devices - In Compliance Magazine

The IEEE published a new standard for4.76 kV to 38 kV rated ground and test (G&T) devices used in enclosures. Although G&T devices have been used as accessory devices in metal-clad switchgear for decades, they were not addressed in the standards until IEEE Std C37.20.6-1997 was approved. The revised standard can be purchased on the IEEE website.

“This standard covers drawout-type, indoor, medium-voltage ground and test devices for use in drawout metal-clad switchgear rated 4.76 kV through 38 kV as described in IEEE Std C37.20.2(TM). Four G&T device types are generally supplied for temporary circuit maintenance procedures for insertion in place of the circuit breaker as follows: a) Simple manual devices b) Complex manual devices c) Simple electrical devices d) Complex electrical devices There may be more complicated G&T devices that may include current and/or voltage transformers, glow tubes, or other accessory components. These more complex devices are not covered by this standard. Due to their complexity, additional testing and interlocking are required, and manufacturers should be consulted for the availability and ratings of these types of devices.” Connection Box Cable Branch Case
