Power quality meters for efficient control of energy

The whole electrical system’s technological development, from generation until load characteristics, has been changing over the past decades and problems affecting electricity supply that were once considered tolerable by the electric utilities and users are now often taken as a problem. Therefore, the quality control of electrical energy has become a major issue for all.

Problem: Bad power quality
Disadvantages of bad power quality are disturbance, data loss, system failure, and damage of systems, sensitive electronic equipment and motors; production failure or damage or defective production; system shutdown caused by under voltage tripping; overheating and/or damage of systems due to overvoltage; reduced efficiency or service life of electrical systems and electronic equipment; harmonic distortion causes motors, transformers, and lines to overheat; failures/mal operation of circuit breakers, relays or fuses; and light flickers.

Reasons of bad power quality
One of the major reasons is harmonics. Also, phenomena such as frequency fluctuations, fluctuations of the voltage level, transient voltage variations (dips, swells, and brief interruptions), longterm voltage variations (overvoltage or under voltage), transients (temporary overvoltage), signal distortion, etc. are also responsible for bringing the quality of power down.

The stand of authorities
Regulating  authorities have considered these problems as serious and brought regulations with penalty provisions and made it mandatory to continuously monitor the power quality using Class A power quality meters for generation utilities, industries, and bulk consumers who are connected to 33 kV and above voltage levels.

Ways to monitor power quality
Power quality is monitored using power quality meters. It is recommended to use CLASS A PQ meters with analyser facilities for best outcome. We at RELISERV SOLUTION can provide you best power quality devices from technology giant SIEMENS. SIEMENS Q100 PQ meters are the best product to help us in this scenario.
