High quality voltage transformer
Voltage transformer is used to change the voltage,mainly used to supply power for the measuring instrument and the relay protection device,also used for measuring the voltage, power and electric energy in the line, or to protect the valuable equipment,transformer and motor from line fault.
Features
√ Small size, high accuracy and good consistency.
√ Excellent in linearity by using high conductivity permalloy or nanocrystalline
√ PCB welding and epoxy resin potting
