Power Factor Corrections
As with any equipment, an electrical system handles its job to some degree of efficiency ranging from poor to excellent. The measure of electrical efficiency is known as Power Factor
Types Of Power Factor
Displacement PF is defined as the cosine of the angle between fundamental voltage and fundamental current of the load.The presence of Harmonics increases the RMS current and voltage relative to their respective fundamental values. This increases the KVA of the Load.
The Power Factor taking into account the effect of the Harmonics is called the TRUE POWERFACTOR.
True PF ≤ Displacement PF
The factor by which Displacement PF is related to the True PF is called the Distortion PF
Only Capacitors can improve Displacement Power Factor
Listed below are various installation options. Care must be taken in sizing and placing power factor correction capacitors. Leading power factor, greater than 100%, must be avoided. The capacitors should only be online when the load requires kVAR and disconnected when the load is reduced.
OPTION A — Install directly at the single speed induction motor terminals (on the secondary of the overload relay).
OPTION B — Install between the contactor and the overload relay. With this option the overload relay can be set for nameplate full load current of motor. Otherwise the same as Option A.
OPTION C — Install between the upstream circuit breaker and the contactor.
OPTION D — Install at the main distribution bus.
System harmonics should be considered when applying power factor correction capacitors. Although capacitors do not generate harmonics, under certain conditions they can Read More
Are you facing a situation where the supply current is lagging the applied voltage? If you are facing such a problem, then you must have power factor correction capacitors made by Power Matrix Solutions Pvt. Ltd. placed so that you can get relief from such effects.
Reasons for having poor power factors
There are basically two reasons for having detrimental power factors. The reasons are:
The power factor of your installations can be improved by placement of power factor capacitors where they work as reactive generators of power. This is required when you notice that the apparent current is superior to the working current that you are getting.
