The switchgear on the low voltage side of the transformers may be located in a building with medium voltage circuit breakers for distribution circuits along with metering control and protection equipment. Medium voltage one line click here to switch to low voltage one line. Switching of capacitive currents. High voltage switchgear and controlgear part 210.

Medium voltage switchgear type simosec up to 27 6 kv extendable metal enclosed up to 1200 a medium voltage switchgear operating instructions description installation operation maintenance order no. While medium voltage conductors are available in 90 c mv90 or 105 c mv105 ratings the actual terminations in the transformer or switchgear cable compartments are limited to 90 c. For example 15 kv switchgear maximum voltage rating is commonly applied at various actual voltages including. 12 47 kv 13 2 kv 13 8 kv and 14 4 kv.

Medium voltage switchgear is classified by the maximum voltage it can service. When sizing the mv cables the nec derating factors must also be applied depending on the type of raceway or duct bank that will be required. Seismic qualification for metal. The most common circuit configurations of high and medium voltage switchgear installations are shown in the form of single line diagrams next paragraphs.
