HV SHUNT REACTOR SECRETS FOR PROTECTION ENGINEERS

Viewed in the substation yard, an HV, oil immersed, shunt reactor does not differ much from a power transformer, but in reality it is not that simple. There are distinct differences between construction and operating characteristics of these two devices. In order to explain the properties of shunt reactors numerous current and voltage waveforms either captured as disturbance recordings in the field or simulated by ATP [7] will be presented. On all these figures the nomenclature for current and voltage signals, as shown in Figure 1 below, will always be used.
