Tackling Power Quality Problems with Iskra Measurement Equipment
Tuesday, 15 September 2020
Understanding Power Quality issues
Most of electric power users understand a term “power quality” purely on a basis of electric power interruptions (power outages). Which is to some extent true. Interruptions are easy to detect they have a direct influence on production process and causes are mostly well known. On the other hand, there are phenomena related to supply of electric power that mostly hard to detect have indirect influence on production process and which causes are mostly not clear. In addition, their influence to production process and product operation is very random and it does not show all the time. Bad power quality consequences can be viewed through technical aspects such as: - Malfunction of appliances, medical equipment, laboratory apparatus… - Burn-out and/or fast ageing of heavy industrial motors - Ageing and destruction of power factor correction capacitors - Stopping or resetting of control systems that depends on computers
Power Quality test and measurement equipment
Power Quality phenomena have usually very short duration, are not periodic and their parameters have very low or extra-large magnitudes. Therefore, it is not possible to try to measure and observe such phenomena by using standard measuring equipment that is used for measuring electrical parameters under normal operational conditions. Measuring equipment that should be used for this purpose is known as “Class A” measuring equipment. It is used when precise measurements are necessary, for example, for contractual applications that may require resolving disputes, verifying compliance with standards, etc. Such measuring equipment is usually certified by an external authorised laboratory that assures proper RMS measuring procedures and data processing methods, real time-clock accuracy and others. Only equipment with certificate can be used for proper and authorised PQ measuring reporting.
ISKRA d.o.o. is a company with many years of experience in development and production of precise and reliable test and measurement equipment for power distribution companies, industry, buildings and traffic automation. Our goal is to provide to customers accurate and precise information about their system operation. With respect to power quality related problems, we have prepared products and services to support customers according to their level of experience and personnel expertise and availability.
