3. Eliminating zero-missing phenomenon in long, high voltage, underground cables
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : The maximum length of an high voltage underground cable (HV UGC) cable is oftenconstrained by the criterion that the cable cannot have more than 50% reactivepower compensation. If this limit is exceeded the current in the circuit breaker maynot have a zero crossing after energization, which is referred to as the zero missingphenomenon. READ MORE
