We are offering draw-out voltage transformer. voltage transformer is also known as potential transformer. design of standard instruments, relays equipment normally does not permit them to be considered directly to the high voltage system. We offer qualitative range of potential transformers that is extensively used in electrical instrumentation systems. Due to transformers' ability to step up or step down voltage and current, and the electrical isolation they provide, they can serve as a way of connecting electrical instrumentation to high-voltage, high current power systems.
