What is a filter?

A filter circuit may be defined as an electrical circuit which is minimized the undesirable AC component from the rectifier output and allows the DC component to reach the load. The filter is used to minimize the


A transformer is a magnetic component or an electric component which transforms electrical a.c. power from one circuit to another circuit without changing the frequency. It works on principle of mutual inductance. Transformers are capable to of

Comparison between analog voltmeter and digital voltmeter

Analog voltmeter Digital voltmeter In analog voltmeter the output signal representation is done by using potentiometric deflection. In digital voltmeter the output signal is represented in the digital form. The different type are: Average reading True rms

Improve quality assurance of electrical insulation in the factory

The latest partial discharge measurement techniques, explored in a CWIEME Berlin seminar, improve quality assurance of electrical insulation in the factory and prevent unnecessary costly repairs or outages in the field. Subject to high mechanical forces and
