10kV relay protection device fault operation time ms
These relays operate within approximately 15 ms All relays configured for high burden applications are suitable for DC operation onlyThese relays operate within approximately 15 ms All relays configured for high burden applications are suitable for DC operation onlyFurther, the duration of the voltage dip caused by the short circuit fault will be shorter, the faster the protection operates. Thus, the disadvantage to other parts of the network due to undervoltage will be reduced to a minimum. The fast operation of the protection also reduc-es post-fault load. The relay settings are first determined to give the shortest operating times at maximum fault levels and then checked to see if operation will also be satisfactory at the minimum fault current expected. Inverse time delay, on the other hand, depends on the current magnitude so, the higher the current, the shorter the delay.
