General comment GE Vernova’s T155-7g Gas Insulated Switchgear (GIS) is composed of different pressurized gas (g3) components. High voltage circuit breakers are mechanical switching devices which connect and interrupt current circuits (operating currents, called rated continuous currents and fault currents, called short circuit currents) and carry the nominal current in closed position. In open position and between phase to ground, it has to withstand the rated voltage. The role of the circuit breaker is to protect and control the electrical power grid. High voltage disconnectors are mechanical switches which isolates elements of the substation to guarantee safe operation on devices for example. Current transformers are used to decrease current intensity in a secondary circuit, in order to allow measurements of the electrical operations conditions. |
