YOU MUST TAKE CARE OF YOUR ELECTRICAL SYSTEM –

FOR EFFICIENT AND SMOOTH RUNNING OF THE SYSTEM

FOR PROTECTION OF YOUR ELECTRICAL EQUIPMENT FROM DAMAGE

FOR INCREASING LIFE OF YOUR ELECTRICAL EQUIPMENT

FOR PROTECTION FROM ANY ELECTRICAL HAZARDS IN FUTURE

FOR REDUCTION OF YOUR ELECTRICITY BILLS

The increased sensitivity of the vast

majority of processes (industrial, services

and even residential) to Power Quality

problems turns the availability of electric

power with quality a crucial factor for

competitiveness in every activity sector.

Power quality determines the fitness of

electrical power to consumer devices.

Without the proper power, an electrical

device (or load) may malfunction, fail

prematurely or not operate at all.

POOR POWER QUALITY CAN LEAD TO-

VOLTAGE FLUCTUATIONS

EQUIPMENT DAMAGE

TEMPERATURE RISE IN CABLES, MOTORS ETC.

LOSS OF ENERGY

DEGRADATION OF ELECTRICAL SYSTEM

SHORT CIRCUITS

AND MANY MORE ISSUES.......

• Variations in the peak or RMS voltage.

• RMS voltage exceeding the nominal voltage by 10 to 80% for 0.5 cycle to 1

minute.

• RMS voltage getting below the nominal voltage by 10 to 90% for 0.5 cycle to 1

minute.

• Random or repetitive variations in the RMS voltage between 90 and 110% of

nominal

• Abrupt, very brief increases in voltage, called "spikes", "impulses", or "surges",

• Under voltage or Voltage drop occurs when the nominal voltage drops below

90% for more than 1 minute.

• "Overvoltage" occurs when the nominal voltage rises above 110% for more than

1 minute.

• Variations in the frequency.

• Variations in the wave shape – usually described as harmonics.

SOME OF THE POWER QUALITY ISSUES

FELIDAE SYSTEMS PM ELECTRONICS



WHY POWER QUALITY INSPECTION IS IMPORTANT ??

YOU MAY NOT BE AWARE OF ISSUES YOU

ARE FACING IN YOUR ELECTRICAL SYSTEM

DUE TO POOR POWER QUALITY

DIAGNOSIS OF POWER QUALITY IS IMPORTANT FOR –

• EQUIPMENT SAFETY

• OCCUPATIONAL SAFETY

• AS WELL AS ENERGY LOSSES




POOR POWER QUALITY NOT ONLY LEADS TO HEAVY ENERGY

LOSSES BUT ALSO RESPONSIBLE FOR SHORT CIRCUITS AND

OTHER ELECTRICAL HAZARDS.

HENCE AUDIT SHALL COVER POWER QUALITY INSPECTION TO

DETERMINE ANY ONGOING ENERGY LOSSES DUE TO POOR

POWER QUALITY OR ANY SAFETY CONCERN FOR EQUIPMENT

LIFE AS OCCUPATIONAL SAFETY.




CASE STUDY ONGC




• AN ENERGY MONITORING SYSTEM WAS INSTALLED

LAST MONTH AT ONGC WHICH RECORDS DAILY

ELECTRICAL & ENERGY DATA

• THE DATA IS CAPTURED ONLY FROM ONE LOCATION

BUT IS GIVING US VALUABLE INFORMATIONS ON THE

BEHAVIOUR OF VOLTAGE AND OTHER PARAMETERS




AS PER THE RECORDED DATA, THE

VOLTAGE TREND IS FOUND TO BE

ABNORMAL IN NATURE WHICH IS ONE OF

THE MAIN REASONS OF POOR POWER

QUALITY




THE VOLTAGE IS FOUND TO BE QUITE FLUCTUATING IN

NATURE AND AS PER THE FIGURE BELOW, IT HAS ALSO

CROSSED THE PERMISSIBLE SHOWING POOR POWER

QUALITY.

THE VOLTAGE LEVEL SHOULD BE MAINTAINED

WELL WITHIN THE PERMISSIBLE LIMITS AT ALL

RUNNING CONDITIONS.

ANY VOLTAGE SPIKE IS UNWANTED AND LEADS TO

POOR POWER QUALITY.




NOW THIS WAS ONLY A SAMPLE RESULT SHOWING VOLTAGE

TREND CAPTURED AT ONLY ONE LOCATION.

WE DON’T KNOW WHAT TYPE OF POWER QUALITY ISSUES

GOING ON AT VARIOUS LOCATIONS WITHIN THE ENTIRE

ELECTRICAL DISTRIBUTION SYSTEM AND HOW THEY ARE

AFFECTING THE ELECTRICAL SYSTEM

SO THERE IS NEED OF THOROUGH INSPECTION OF THE

ELECTRICAL SYSTEM AND THIS IS WHY YOU NEED TO

GO FOR POWER QUALITY AUDIT OF YOUR ELECTRICAL

DISTRIBUTION SYSTEM




• POWER QUALITY AUDIT WILL HELP YOU DETECT ALL

KINDS OF ONGOING POWER QUALITY ISSUES

• IT SHALL HELP YOU UNDERSTAND THE PROBLEMS

RELATED TO THOSE ISSUES

• IT SHALL GUIDE YOU IN BEST MAINTENANCE OF YOUR

SYSTEM

• IT SHALL SUGGEST YOU HOW TO AVOID ANY FUTURE

EQUIPMENT FAILURES ETC..




ONGOING PROBLEMS IN LIFTS AT THE ONGC – NOIDA CAMPUS

CAN BE DUE TO POOR POWER QUALITY.

ACTUAL ROOT CAUSE OF IT’S MALFUNCTION CAN’T BE

DETECTED UNLESS YOU OPT FOR POWER QUALITY INSPECTION.

IT’S DIFFICULT TO SAY WHAT KIND OF POWER QUALITY ISSUE

AFFECTING YOUR LIFTS NOW.

ATLEAST YOU WILL BE ABLE TO SOLVE THE PROBLEM IF THE

MALFUNCTION OF YOUR LIFTS IS DUE YO ANY OF THE POWER

QUALITY ISSUES.




SO POWER QUALITY AUDIT IS IMPORTANT-

• TO DETECT ANY POWER QUALITY ISSUES

• REASONS FOR POWER QUALITY ISSUES

• TRACE THE AREA WHICH IS CREATING PROBLEMS

• SUGGEST BEST REMEDIES.




OPT FOR POWER QUALITY AUDIT

• PROTECT YOUR ELECTRICAL EQUIPMENT FROM DAMAGE

• PROTECT YOUR ELECTRICAL DISTRIBUTION SYSTEM

• AVOID ANY ELECTRICAL HAZARDS

• SAVE ANY ONGOING ENERGY LOSSES

DOCTOR TELLS IT'S AFFECT ON YOUR BODY WE EXPLAIN THE AFFECT ON ELECTRICAL SYSTEM

DOCTOR SUGGESTS CURE WE RECOMMEND BEST SOLUTIONS AS APPLICABLE




POWER QUALITY AUDIT SHALL HELP YOU IN SMOOTH

RUNNING OF YOUR SYSTEM AND KEEP YOU SAFE AND

SOUND AS WELL HAVE MONETARY GAINS.




WHERE THE STUDY SHALL BE CONDUCTED ??




POWER QUALITY INSPECTION IS DONE AT THE MAIN HT/LT

PANEL WHERE THE POWER ENTERS YOUR FACILITY.

IT IS CARRIED ON TO THE VARIOUS ELECTRICAL FEEDERS

ALSO COVERS THE LOAD END

POWER

QUALITY

INSPECTION

PM ELECTRONICS


ALSO GO FOR HOT SPOT ANALYSIS

PM ELECTRONICS


• IT’S NOT POSSIBLE TO DETECT ANY LOOSE

CONNECTIONS OR RUSTING ISSUES INSIDE

ELECTRICAL PANEL CABLES, BUS BARS,

DISTRIBUTION BOARDS AND OTHER AREAS

WITHIN THE ELECTRICAL SYSTEM BY

VISUAL INSPECTION

• USE OF HIGHLY

EFFICIENT THERMAL

CAMERA DONE TO

CAPTURE HOT SPOTS.

IMPORTANT FOR

ENERGY

CONSERVATION AS

WELL FOR SAFETY

ISSUES.

• AVOID SHORT CIRCUITS

• PROTECT YOUR ELECTRICAL EQUIPMENT

FROM DAMAGE

• PROTECT YOUR ELECTRICAL SYSTEM

• STAY SAFE
