Electricty is generated at around 16kV, then step up to
220kV for transmission then steped down to power
transformers then DTs and then through the LT n/w it reaches
the consumer end.
At the consumer end 230V supply is required. So, why is
electricity not generated directly at 230V and transmitted?
Answer Posted / anil kumar verma
power is generated at power plants which are generally
situated at far distance from the actual users at 220
volts. so power has to be transmitted to these users. if
power is transmitted at 220 volts then due to high currents
at low voltage transmission losse will be very high & very
low voltage will be experienced at consumer end. so to
minimise the losses power is generated & transmitted at
high voltage. moreover generation & transmission at 220
volts will not be cost effective.

During Testing of Maintenance Free Earthing, How deep should be the Spikes of Earth Test Meter should be inserted in the soil(one spike is 15 Meter & Other spike is 30 Mtrs away from the Main Earth Electrode. Because, recently, we observed that when spike is inserted 3-4 Inch in the earth- results are better, If spike is inserted 1 feet deep than results are increasing.
