Earth fault is an undesirable condition at which current flow from a conductor to earth. This can happen when a current-carrying conductor falls on the ground or the body of…
When a circuit breaker interrupts high currents, an electric arc is generated. An electric arc is the discharge of electric current through gas or air. The conduction of electric charges…
A relay is an electrically controlled switching device. It consists of an electromagnet and a set of contacts that open or close when voltage is applied to the electromagnet. It…
Power is transmitted over long distances at high voltage. In order to supply domestic and residential applications, it needs to be stepped down to 120V or 230V single phase. This…
Electrical engineers and electricians follow predefined wiring colour codes while wiring houses, commercial buildings and industrial panel boards. The electrical wiring colour codes followed is slightly different in every part…
In every control circuits and automation systems, logic is developed based on the open or closed state of switches, sensors or relays. Hence it is mandatory to know the concept…
Use the following calculator to calculate voltage regulation of a transformer. Enter Vno-load and Vfull-load and click on calculate button Use the below online voltage regulation calculator Enter No-Load Voltage…
Kilowatts and ampere are two different quantities of electricity. While the former quantifies the amount of power consumed by a load at any instant the latter quantifies the amount of…
Voltage regulation of transformers can be a little tricky to understant. Every piece of equipment is designed to operate at a particular voltage or voltage range. Therefore, it is a…
