BS EN 60871-4 is the fourth part of the multi-series standard used for Shunt capacitors for AC power systems having a rated voltage above 1 000 V that specifies the test methods and procedures for internal fuses. This helps in manufacturing good quality internal fuses used in shunt capacitors for AC power systems.
BS EN 60871-4 applies to internal fuses which are designed to isolate faulty capacitor elements, in order to allow the operation of the remaining parts of that capacitor unit and the bank in which the capacitor unit is connected. Such fuses are not a substitute for a switching device such as a circuit-breaker, or for external protection of the capacitor bank or any part thereof.
BS EN 60871-4 on Internal fuses used in shunt capacitors for AC power systems is useful for:
A shunt capacitor is extensively used to transmit reactive power to loads in the main distribution. These capacitors are useful in supplying an economical reactive power to meet up reactive power necessities for different loads.
BS EN 60871-4 specifies the test method and test procedure for internal fuses used in shunt capacitors. The test methods are as follows:
BS EN 60871-4 specifies the performance requirements that help in determining and evaluating the performance of these internal fuses. This results in manufacturing good quality internal fuses used in shunt capacitors for AC power systems.
