Neutral system – Single earthed or Multi earthed?
In distribution system three phase load is unbalance and non linear so the neutral plays an very important role in distribution system. Generally, distribution networks are operated in an unbalanced configuration and also service to consumers. This causes current flowing… Read more

Low Voltage
Types Of Electrical Power Distribution Systems You Should Know About
Electrical power is distribution either three wires or four wires (3 wire for phases and 1 wire for Neutral). Voltage between phase to phase called Line Voltage and voltage between phase and neutral is called Phase Voltage. This forth wire… Read more

The Advantages Of Maintaining A High Power Factor
A high power factor eliminates penalty dollars imposed when operating with a low power factor. For many years, most utilities demanded a minimum of 85% power factor as an average for each monthly billing. Now many of these same utilities… Read more
