On the other hand, current disturbances originate at a customers installation and affect the network components and other installations. Voltage disturbances commonly originate in the network and affect the customers. A PQ disturbance occurs in case of any deviation of voltage and current waveforms from the ideal. Simply put, Power Quality is a measure of quality of power supply on the grid. loose connections lead to sparking poor quality of wires results in voltage drops at customers premise, etc.įurther on, we shall focus upon 3 key stakeholders – Customers, Network Operators and Equipment Manufacturers.
Maintenance engineers are subsequently responsible for preventing any glitches in operations which can result in power quality issue. Good installation is one of the necessities to maintain power quality during operations and to minimize voltage drop, sparking, overheating, etc. In addition to above 3 key stakeholders, there are others like – Designers, Commissioning Engineers and Maintenance Engineers that also plays role in sustaining good PQ environment.Commissioning Engineer play the role in ensuring the quality of installation based on certain design standards. Network Operator will blame his end-customers, Device Manufacturer will blame both the Network Operator and the end-customer, and end-customer usually has not much awareness, and believe that its supply problem from Network Operator. See APQI earlier blog that tries to quantify economic impact from poor PQ environment – Are developing economies at risk due to power quality issues and challenges?Īnother follow-up question will be WHO IS RESPONSIBLE FOR MAINTAINING GOOD POWER QUALITY? Answer to this is usually divided and depends upon whom we pose this question. India and most developing countries continue to struggle for 24×7 power supply, good Power Quality (PQ) environment, and Energy Efficient (EE) economy.
