UPS means Uninterruptable Power Supply. Its function is to
convert AC power into DC and store in a Battery when AC
supply is interrupted (no electricity, under voltage or over
voltage) then UPS act as a power supply by Inverting DC to
AC from the charged Battery.

Answer / ponnamalla venkata satish

ups means uninterpted power supply it is play very
important role in industrial process because the field
intruments should give continous signal to the control
system and if in case power has shut down due to abnormal
condition in plant then also control system need some
process parameters to avoid hazards so ups can give
continous supply to the field instrumens and as per the
requirment in the process

Answer / sunil guru

BASIC USE AND RUNNING OF UPS IS WRITTEN ABOVE ....
LET ME GIVE SM DETAIL EXPLANATION

UN-INTERRUPTIBLE POWER SUPPLY(UPS)---- HAS BASIC 6 CIRCUITS FOR ITS COMPLETE WORKING

1> MAINS UNDER AND OVER VOLTAGE CUT-OFF CIRCUIT
2> BATTERY CHARGER CIRCUIT
3> RELAY CHANGE OVER CIRCUIT(FROM MAIN TO BATTERY MODE-IN ABSENCE OF UTILITY)
4> BATTERY DEEP CUT OUT CIRCUIT (AT LOW BATTERY THIS CKT WILL CUT OFF BATTERY FROM CKT)
5> INVERTER CONTROL CIRCUT (CONVERTS FROM DC TO AC)
6> POWER OUTPUT STAGE (WITH THE HELP OF TIMER(555),TRANSISTOR AS A SWITCH AND USING MOSFET OR IGBT WITH APPROPRIATE DRIVER TO SWING DIRECT CURRENT TO ALTERNATING AT 180 DEGREE PHASE DIFFERENCE AND PRODUCING 50 HZ FREQ WE CAN DELIVER THE 220 V AC POWER

3 Answers   Reliance,

For polarity test on a 11/3.3kV 2.5MVA delta-star Unit Auxiliary transformer,415V 3-phase supply was applied at the HV. Connection between Aa was made with a 2.5mm cable. As soon as power was switched on the cable caught fire and burnt. This test was then abandoned. It is noteworthy to say that a similar cable was also used in a similar transformer for the same. The cable did not burn and test was successfully completed with good result. What is wrong? Please, help me out.
