PRESENT DAY ELECTRICAL POWER SYSTEM MEANS A MASSIVE GRID CONNECTED SYSTEM WHERE EACH AND EVERY ELEMENT IS OPERATING AT A SYNCHRONOUS SPEED OF 50 /60 HZ. SO, DURING CONNECTION OF ANY NEW GENERATOR OR SYSTEM TO THE POWER GRID /NETWORK/SYSTEM IS IS MANDATORY TO CHECK WHEATHER THE INCOMING MACHINE IS RUNNING AT SAME FREQUENCY OF THE GRID OR NOT. THIS CHECKING IS PERFORMED BY #SYNCRONOSCOPE. FOR THIS #SYNC TROLLEY WAS USED EARLIER. BUT, NOW A DAYS THIS FACILITY IS ALSO AVAILABLE IN NUMERICSL RELAYS OR BCU. IN THIS VIDEO WE WANT TO DEMONSTRATE THIS IN A P143 RELAY.
IF FREQUENCY OF TWO SYSTEM ARE NOT SAME BUT HAVE A VERY SMALL DIFFERENCE THAT MEANS ONE SYSTEM IS AT A FASTER SPEED OR FREQUENCY THAN OTHER. THIS DIFFERENCE OF SYSTEM FREQUENCY IS CALLED #SLIPFREQUENCY. IN THIS VIDEO SLIP FREQUENCY IS DEMONSTATED BY INJECTING TWO VOLTAGE OF DIFFERENT FREQUENCY.
