5 REASONS TO PERFORM A POWER QUALITY ANALYSIS

The electrical quality is an indicator of the level of adequacy of the installation to support and guarantee the reliable operation of its loads. In this article, we will tell you the benefits that you can obtain when performing a power quality analysis.

WHAT IS THE QUALITY OF ELECTRICAL ENERGY?

The IEC 61000-4-30 standard defines the quality of electrical energy as the “characteristics of electricity at a given point in an electrical power network, evaluated in relation to a set of technical reference parameters”. On the other hand, the IEEE 1159-1995 standard defines the quality of electrical energy as “a great variety of electromagnetic phenomena that characterize voltage and current at a given moment and at a certain point in the electrical network.”

In general, the quality of electrical energy is understood when electrical energy is supplied to equipment and devices with the appropriate characteristics and conditions that allow them to maintain their continuity without affecting their performance or causing failure of their components. Therefore, when we talk about power quality, we are referring both to the quality of the voltage and current signals, and to the continuity or reliability of the electric power service.

WHY SHOULD A POWER QUALITY ANALYSIS BE PERFORMED?
  1. SECURITY

Before adding a new electrical load to an existing panel or equipment, a load study should be conducted to determine if sufficient capacity is available to add new charges. The load study involves the use of an electric logger to document current load levels (loss of three-phase current) over time. Therefore, a load study can be used to ensure compliance with local safety regulations and much more importantly, carrying out a load study before adding new loads can avoid overloading an existing outlet, giving you guarantees greater safety and reliability.

  1. SAVINGS IN ENERGY COSTS

We know that energy costs are an important part of the total operating cost. However, many companies do not know what they spend their resources on specifically, companies usually only pay the total amount of the invoice, but they cannot assess if their spending is normal or excessive compared to the operations of other months. Today, it is possible to see how much energy the company consumes, when, in what and at what rate / schedule, simply by recording the energy use in primary and secondary activities. These data will help you discover different energy costs, which can only be rectified with operational changes, such as the disconnection of certain loads, reduction of loads during periods when the rate is more expensive or modifying operating hours to more periods. Cheap.

  1. GREATER PRECISION IN THE ELECTRIC BILL

Owners of large and medium-sized power plants often install auxiliary meters to their tenants to monitor their specific electricity consumption, but many of these meters are incorrectly installed, questioning actual consumption. Installation problems are variable; from voltage transducers installed backwards or in the wrong phase, to configuration errors in the auxiliary meter. Therefore, it is recommended to check the readings with an energy analyzer. Recording the data provides a compelling argument when comparing billing data with actual energy consumption, a significant difference between the amounts billed and the data from the logger will indicate that a configuration review should be performed and / or installation of the auxiliary meter.

  1. FINANCIAL INCENTIVES

Currently, some government organizations offer incentives and discounts to encourage a reduction in energy consumption. There are different incentives and discounts for modernizing buildings; such as efficient lighting solutions and high efficiency motors, as well as the replacement of motor starters with variable frequency drives. To grant these benefits, companies require verification of their energy savings: the ideal scenario for a load study. A load study prior to such modernization will serve to document current energy expenditure and to provide a baseline, while a subsequent study will serve to verify the savings achieved upon completion of improvements.

  1. TROUBLESHOOTING

Sometimes the only way to solve a problem is to capture and analyze the data over a long period of time. In these cases, energy analyzers are an excellent option; since they are accessible and easy to use, in addition to providing the user with more complete information. For example, suppose we have a circuit breaker that has erratic operation, the most obvious events such as starting a high-powered motor may not be the cause, in fact the cause of the failures may be totally random or occur when technicians are not present. It is quite difficult for a maintenance technician to control a load until the circuit breaker failure occurs.
