Neptune’s power factor correction system to prevent resonance condition in order to avoid operational problems and damage to capacitors
Power factor correction or reactive power compensation forms a small but very important part of electrical scheme of any electrical network which source its supply from electrical utility company. It’s inadequacy in any form can result in power losses, voltage drop, increase in peak demand, untilised transformer and cable capacity. With most of the electricity companies billing in KVAH units, there is direct losses in terms of higher units if power factor of installation is maintained below unity.
Most common method of improving power factor is to install power capacitor banks at load side or mains. The power factor will be improved but depending on the type and characteristics of load the system if not designedproperly can interact with network to generate resonance condition and other negative impacts. Therefore, it is imperative to follow certain guidelines for design of power factor correction system to prevent resonance condition in order to avoid operational problems and damage to capacitors.
Power quality and importancePoor power quality, particularly high harmonic distortions, can lead to resonance condition leading to operational problems and subsequent operating losses. Some of the consequences can be:•Breaker tripping, burning and blowing frequent equipment failures, failure in electronic equipment, software glitches•High KVA demand, poor power factor, operational problem in DG supply on change overBurning or overheating of capacitors, transformers, wires, cables, bus bar and switchgear componentThere has been much discussions and interests in recent years on the subject of power quality, particularly harmonics under ambit of network power quality. More and more frequently industrial and commercial users are finding that they have to deal with the problem of “polluted power”. Many seminars and awareness programmes have been conducted to effectively deal with problems of harmonics. It is very common to hear about capacitor explosions, switchgear burning and tripping and problems because of voltage transients in electrical power industry.A lot has been done but still there are gaps in knowledge of harmonics in network and methods to effectively deal with them. It has to be understood that power quality and harmonics is one area of expertise within electrical discipline. Like other areas of power distribution, lighting and so forth the area also needs to be take care off while designing the electrical layout and reactive power compensation system. In existing system, power quality studies assume great significance to understand network power quality profile and negative impact they can have on network.
Neptune offer high-quality power quality studies for short durations, 24 hours to many days by high-end waveform and PQ recorders so that to comprehensively understand harmonics, voltage flicker, voltage fluctuation (sags and spikes), power factor issues during various load cycles of plant and office and their impact.
