What is a Digital Multimeter? Digital Multimeter also famous as DMM is simply an electronic instrument that measures electrical parameters including AC/DC volts, AC/DC current, resistance. In addition digital multimeter may have a variety of special features that are designed for a
The phenomenon of ionization of surrounding air around the conductor, hissing noise and production of Ozone gas in an overhead transmission line is known as Corona Effect. Corona discharge is a process by which a current flows in a conductor with a
In this method of inter-connection the similar ends either the ‘start’ or ‘finish’ are joined together at point N. This common point N is called star point or neutral point. Ordinarily only three wires are carried to the external circuit giving 3-phase,
The opposition to flow of electrons (due to bonds between protons and electrons, as well as to collisions) is called a electrical resistance (R). Or Resistance may also be defined as “The property of the electric circuit which opposes the flow of
What is voltage stabilizer? Voltage stabilizer is an equipment that stabilizes voltage. The process of stabilization happens by bringing voltage to a desirable level whenever there is any kind of fluctuation in the power system. Therefore we can say that voltage stabilizer
Differential busbar protection is the most common and reliable scheme for the bus bar protection. Earlier there was no other option to use only conventional over current relays for busbar protection. But it is desirable that fault in any feeder or transformer
