15kV Earthing Switch Specification
15kV Earthing Switch Specification
(OP)
Does anyone have a good source/description for 15kV earthing switches? Our company is installing a 5MW/13.8kV generator and the local utility is requiring an earthing switch on the generator main circuit. This will be an indoor piece of gear. Can we use a simple fused disconnect wired to ground or a new cube in the existing switchgear lineup? I am looking for a way to spec this item.
Thanks in advance for your assistance.

The earthing switches are delivered built-in in switchgear with safety interlock with circuit breaker [see the attachment]. For example how to concept a specification see the link.

The existing CB is GE PowerVAC breaker on the turbine generator breaker. The utility won't give access to their switchgear lineup, and is requiring us to provide the earthing switch. It looks like we're going to need a stand-alone section or switch between the turbine and the utility (the turbine feeds power from it's CB to the utility's distribution switchgear lineup). They want the earthing switch to ensure the turbine CB is grounded when the turbine CB is opened.
