Although the majority of these switches are air insulated gas insulated sf6 combination switches are available which are designed for load and fault current switching.

Medium voltage switchgear grounding.

New approaches for maintenance grounding in medium voltage switchgear schneider electric white paper revision 0 page 5 a third practice used is main grounding. Medium voltage switches for use on 1 52kv indoor systems are predominantly used for isolation and earthing. Bond the equipment grounding conductors to the switchgear ground bus to all manhole grounding provisions and hardware to the cable shield grounding provisions of medium voltage cable splices and terminations and to. 70 savings with 30 kv compared to air insulated switchgear.

Maintenance grounding is a proven method for protecting electrical workers during medium voltage switchgear maintenance. Gas insulated switchgear should be used for the medium voltage consumer substation. Modern grounding switches allow personnel to perform maintenance grounding with switchgear completely enclosed. Eaton s medium voltage ground and test devices are used to apply temporary grounding to the phase conductors of switchgear during maintenance and testing of the equipment.

Smaller transportation size and consequently easier shipping. Lower space requirements up to approx. The following should be noted. When applied properly it eliminates dangerous differences in electric potential and can redirect harmful current during events such as unforeseen induced voltage.

Conductor in each duct containing medium voltage conductors sized per nec except that minimum size shall be no. The advantages of gas insulated switchgear are. In this method the ground is applied to the line side of the main switch or circuit breaker in switchgear figure 3a. The benefits of this method.

When terminating medium voltage cables in to a switchgear with zero sequence ct core balance ct the cable shield needs to be routed as discussed below for ground fault relay to operate properly.
