Improvement of Fuses to Increase the Efficiency of Medium Voltage Instrument Transformers Protection
Abstract: The paper considers an improved design of a fuse for the protection of the medium voltage instrument transformer. The problem of switching off by fuses of small overload currents and the low ...
Abstract: Current Transformers (CTs) produce scaled values of primary currents suitable for protective relays and measuring devices. For the correct implementation of protective relays and proper use ...
