The reference list shall indicate the following a. Highest Voltage Level b. High Voltage Levels worked at c. Medium Voltage Levels worked at d.. Jan 02, 2019 · Feeders. The problem can be overcome by using earth leakage circuit breaker. This operates on low leakage current. The earth leakage circuit breaker can detect leakage current as low as 100 mA and is capable of disconnecting the appliance in less than 100 msec. A typical diagram of low voltage switchgear is shown above..
After assembly, the complete switchgear shall be tested to ensure the accuracy of the wiring and the functioning of all equipment. The main bus system shall be given a dielectric test of 2200 volts for one minute between live parts and ground and between opposite polarities.. AX1 Manual 1VET954300-905 e rev D 1-19. # ˙ˇ˘ +) . The medium voltage switchgear AX1 consists of the following cubicle types: • Incoming feeder (circuit-breaker) cubicle. Standard design with cable connections from the front at the bottom (options for cable connections from the rear at the bottom).. generators of high power (100MVA to 1800 MVA) in order to protect them safely, rapidly and in an economical way. They must be able to carry high continuous currents (6300 A to 40000 A), and they must have a high short-circuit breaking current.
