Eaton announced that its Cooper Power Systems division has launched an external visible loadbreak solution for medium voltage transformers. It was designed to provide visible verification of an electrical circuit’s disconnect and grounding to result in enhanced safety and reduced maintenance and operating costs.
The visible loadbreak switchbox is placed on the side of the transformer where there are no live circuits and has a large inspection window, rotary handle for operating the contacts and padlocked covers on the switch and window. In addition, the on/off/ground functionality allows the end user to internally ground the transformer windings to the tank, utilizing the loadbreak switch. This option can be specified with external, tamper-proof gauges.
“Nearly every maintenance procedure on a transformer requires manually entering the live compartment and wearing protective equipment in order to ensure the circuit is properly isolated,” said Jack Moore, associate global product director, Substation and Underground Transformers, Eaton’s Cooper Power Systems division. “This solution is one of the first options in the U.S. that allows for verification externally, through the use of a clear viewing window.”
This technology is available for applications from 0.5 to 3 Megavolt Ampere (MVA) and a voltage class of 15 to 35 kilovolt (kV).
