A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.
Transformers are used to increase or decrease voltage levels in electrical circuits.
They consist of two coils of wire, known as the primary and secondary coils.
The primary coil is connected to a power source, while the secondary coil is connected to the load.
The changing magnetic field i...
ACB stands for Air Circuit Breaker, which is a type of circuit breaker that operates in the air as an arc extinguishing medium.
ACB is used to protect electrical circuits from overloads and short circuits by automatically disconnecting the power supply when a fault is detected.
It consists of a set of contacts that open and close to interrupt the flow of current in the circuit.
ACBs are commonly used in industrial and com...
DG Safety device is a safety device used to protect diesel generators from damage or malfunction.
DG Safety device monitors parameters like temperature, oil pressure, and voltage to ensure safe operation.
It can automatically shut down the generator in case of any abnormal readings to prevent damage.
Examples of DG Safety devices include automatic voltage regulators, engine control modules, and temperature sensors.
Transformer safety refers to measures taken to prevent accidents and ensure the proper functioning of transformers.
