UPS Presentation

A Unique presentation on UPS

1. INTRODUCTION After completion of this presentation a student will be able to understand: 4 WHAT IS UPS? DEFINE UNINTERRUPTIBLE POWER SUPPLY? WHAT IS THE ALTERNATE NAME OF UPS? WHY USE A UPS ? UPS COMPONENTS? Presented By: Azmat Abbas Rana Instructor Electronics Govt Technical Training institute sillanwali road sargodha

2. define UNINTERRUPTIBLE POWER SUPPLY? AN UNINTERRUPTIBLE POWER SUPPLY (UPS) IS A CRITCAL DEVICE (INHOMES,COMPANY,SITES) THAT HAS AN ALTERNATE SOURCE OF ENERGY THAT CAN PROVIDE EMERGENCY POWER WHEN THE PRIMARY POWER SOURCE IS TEMPORARILY DISABLED

3. What the alternate names of UPS UPS System Uninterruptible power supply System Uninterruptible power Source System Battery Backup System

4. WHY we USE A UPS? PROTECTS AGAINST MULTIPLE TYPES OF POWER DISTURBANCES ONLY DEVICE THAT PROTECTS IS UPS OFFERS PROTECTION AGAINST COMPUTER AND EQUIPMENT DAMAGE DATA LOSS,BUT DUE TO UPS IT MAY BE SAVED

5. CAUSES OF POWER DISTURBANCES STORM ACTIVITY – LIGHTNING, WIND, ICE OBJECTS COMING IN CONTACT WITH POWER LINE AND TRIPPING BREAKER – TREE BRANCHES, ANIMALS, OTHER CONSTRUCTION ACTIVITY ACCIDENTS – MOTOR VEHICLE, OTHER EQUIPMENT FAILURE OVER LOADING NON-LINEAR LOADS POOR GROUNDING

6. Cavitation

7. PROBLEMS RESULTING FROM POWER DISTURBANCES DATA ERRORS DATA LOSS BLOWN FUSES TRIPPED BREAKERS OVERLOADED NEUTRAL CONDUCTORS MOTORS HEATING SPEED VARIATION VIBRATION TRANSFORMERS HEATING AUDIBLE NOISE

8. UPS COMPONENTS 14 AC TO DC CONVERTER BATTERY INVERTER BATTEY CHARGING UNIT SOFTWERE CONTROL SWITCHES

9. CONVERTER - AC TO DC PROTECTS AGAINST SPIKES AND TRANSIENTS WE USE IT IN DAILY LIFE TO CHARGE,CAR BUS BATTERIES

10. BATTERY ENERGY STORING DEVICES CONVERT CHEMICAL ENERGY TO ELECTRICAL ENERGY

11. INVERTER – DC TO AC VOLTAGE REGULATOR – PROTECTS AGAINST SAGS, SURGES AND FLUCTUATIONS

12. BATTERY CHARGING UNIT VOLTAGE REGULATOR RESPONSIBLE TO BATTERY CHARGING PROTECT OVER CHARGING

13. MONITOR AND CONTROL HARDWARE / SOFTWARE Control all the operation of UPS

14. Cavitation C avitation  is the formation of bubbles or cavities in liquid, developed in areas of relatively low pressure around an impeller. The collapsing of these bubbles trigger intense shockwaves inside the pump , causing significant damage to the impeller and/or the  pump.

15. GENERAL DISCUSSION 21 DOES A UPS OFFER COMPLETE PROTECTION? DO YOU THINK “POWER DISTURBANCES WON’T HAPPEN TO YOU” ?

16. DOES A UPS OFFER COMPLETE PROTECTION? 22 SOME POWER DISTURBANCES MAY EXCEED THE HANDLING CAPABILITY OF THE UPS. UPS FAILURE

17. DO YOU THINK “POWER DISTURBANCES WON’T HAPPEN TO YOU” ? 23 POWER DISTURBANCES OCCUR FREQUENTLY, THOUGH MANY ARE SMALL AND WITH OUT CONSEQUENCE AN ON-LINE UPS CAN PROTECT AGAINST MORE SIGNIFICANT POWER DISTURBANCES WHEN THEY DO OCCUR

18. Recapitulation THINGS TO CONSIDER WHEN SPECIFYING A UPS 24 POWER QUALITY ARCHITECTURE - LINE INTERACTIVE OR ON-LINE IMMUNITY TO DISTURBANCES OTHER THAN OUTAGE RUN TIME RELIABILITY AUDIBLE NOISE MONITOR AND CONTROL HARDWARE / SOFTWARE LOC AL / REMOTE CONTROL INITIAL COST MAINTENANCE COST WARRANTY

19. ? Can we store the electricity easily?

20. Yes we store it only means till now are batteries SO THE BATTERIES ARE MAJOR COMPONENTS TO STORE ELECTRICTY

21. battery STORE ENERGY Consisting ONE OR more   cells two electrodes positive terminal , anode, negative terminal, cathode Change Electrochemical energy to electrical energy

22. Conclusion Dear student today we discuss about UPS WHAT IS UPS? DEFINE UNINTERRUPTIBLE POWER SUPPLY? WHAT IS THE ALTERNATE NAME OF UPS? WHY USE A UPS? UPS COMPONENTS Tomorrow we shall discuss about Solar System.
