  • High Voltage Switchgear | Electrical4U

    Oct 23, 2020The power system deals with voltage above 36KV, is referred as high voltage switchgear.As the voltage level is high the arcing produced during switching operation is also very high. So, special care is to be taken during the designing of high voltage switchgear.High voltage circuit breaker, is the main component of HV switchgear, hence high voltage circuit breaker should have

    Oct 25, 2020In American (120 V) systems, the customers are commonly supplied directly from the distribution transformers via relatively short service drop lines, in star-like topology. In 240 V systems, the customers are served by several low-voltage feeders, realized by overhead power lines, aerial or underground power cables, or their mixture.

    Apr 22, 2016The break point is typically somewhere between 200 and 500 HP (or kW), although MV motors are available at lower powers and LV motors at higher powers. The LV motors will draw higher current, so cabling, switchgear, etc., must be sized accordingly. But LV equipment is less expensive than MV
