Generators in parallel

When generators are operated in parallel condition,it necessary to be arrange for both real power ( kW ) and reactive load ( kVar ) sharing in proportion to their standard rating.Real load output from generator determined by torque applied to the shaft and this can only be controlled by controlling the prime mover driving the generator.

Reactive load is a function of generator excitation.Under parallel operation,adjustment to field excitation does not affect to output voltage.In general,an under-excited machine will generate at a more lagging power factor current.

The three phase sensing regulator operates in similar manner except that the voltage across the reactor carrying a current proportion to one phase current is added to the voltage of that phase. read more

Generator Rating

Usually the generator is designed to capable to delivery the power supply required due to time basic ( hour ) to ensure reliable operation and prevent serious breakdown.

Typically a given set can deliver more power for fewer hours per year, or less power continuously. That is a standby set is only expected to give its peak output for a few hours per year, whereas a continuously running set, would be expected to give a somewhat lower output, but literally continuously, and both to have reasonable maintenance and reliability. read more

How to wiring a plug 13 ampere

Wiring for 13 amp plug top

A 3 pin plug used in most electrical appliances.It has a 13 ampere fuse is rated to protect electrical equipment from overload or short circuit.

This time I will show how to wiring a plug step by step:-

1) Open a cover using a Philips screwdriver.we can see the terminal blockĀ  inside a plug.
