Electric PotentialTransformer
The electrical potentialtransformer is fully closed and encapsulated with epoxy resin coating. Thisprovides the transformer with outstanding mechanical performance, environmentalresistance, and good voltage insulation property. Light and small, theelectrical potential transformer is not only beautifully designed, but easy toinstall as well. As most iron cores of the transformer are made of new magneticmaterials of high initial permeability such as iron-nickel alloy and nanocrystalline, the electrical potential transformer hasgood output linearity and high precision. Note that under PCB installationmode, current limiting resistors will be needed at primary winding.
The electric potential transformer can be used in electricaltransducer, electronic power energy meter, precision power meter, electricalpower monitoring instruments, voltage monitoring and measurement, etc.
