There are two types of Transformer Tap Changer:
load regulation and excitation free regulation. The former can only adjust the position of the Tap Changer when the transformer is disconnected from the power grid, while the latter can adjust the position of the tap changer during transformer operation mode. If there are no special requirements for general transformers, no load voltage regulating tap changer shall be used.
WST series off-circuit Tap Changer (Linear form)
This kind of switch applies to the single-phase, three phase, combination Oil Immersed Transformer electrical power with frequency of 50HZ, 60HZ, rated voltage of 10KV, 35KV, rated current of 30A~500A; The voltage-regulating mode are:
central part, terminal point ncutral point, which canbe dircctly fixed on the tank cover of the transformer, exchange under the off-circuit condition.
