Step Up Transformer- Working, Output Voltage and Application

A step up transformer is an electrical device used to convert low-voltage (LV) electricity to high-voltage (HV) electricity. It consists of two or more coils of wire wound around a magnetic core. The primary coil, connected to the input, receives the low-voltage electricity. The secondary coil, connected to the output, delivers the higher voltage electricity….

Step Down Transformer- Working, Output Voltage and Application

A step down transformer is a type of electrical device that is used to convert high voltage (HV) electricity to low voltage (LV) electricity. It consists of two or more coils of wire wound around a magnetic core. The primary coil, connected to the input power source, receives the high-voltage electricity. The secondary coil, connected…

Anti pumping relay in Circuit Breaker –Diagram, Working principle

Anti pumping relay is used in the circuit breakers to prevent unwanted closing of the breaker after immediate tripping. Due to failure of the TNC switch (Trip normal close) or any other discrepancy in the CB closing circuit, continuous CB close command can be extended to the closing coil. In that condition, after tripping the…
