Power Quality Analysis

Power quality determines the fitness of electrical power to consumer devices. Synchronization of the voltage frequency and phase allows electrical systems to function in their intended manner without significant loss of performance or lifespan.

In its broadest sense, power quality is a set of boundaries that allows electrical systems to function in their intended manner without losing performance or premature failure. The term is used to describe electric power that drives an electrical device and the device’s ability to function properly with that electric power. Without the proper power, an electrical device may malfunction, fail prematurely or not operate at all. There are many ways in which electric power can be of poor quality and many more causes of such poor quality power.

At Elion our experienced team survey and analyze your electrical installations, for the purpose of establishing the quality of the electrical supply. Using the latest power quality analysis equipment we are able to identify potential issues with the quality of your power and reduce your business losses.

It has been found that with increased use of electronic component like UPS, CFL, Computers and more there are disturbances in electrical systems which unbalance the system and create problems like –

• Voltage sags and surges,
• Power interruptions,
• Harmonic distortion,
• Ground loops,
• High speed transients,
• Electrical noise,
• Lightning damage

Each of these power quality problems has a different cause. Some problems are a result of shared infrastructure. For example, a fault on the network may cause a dip that will affect some customers and the higher the level of the fault, the greater the number affected, or a problem on one customer’s site may cause a transient that affects all other customers on the same subsystem. Other problems, such as harmonics, arise within the customer’s own installation and may or may affect the network and so affect other customers. Harmonic problems can be dealt with by a combination of good design practice and well proven reduction equipment.

Elion is a full-service Power Quality Consulting firm dedicated to providing clients with a complete analysis of their electrical power, telecommunications and data transmission systems. We identify system problems, review operational integrity and safety issues, and make recommendations for procedures and equipment designed to correct or avoid future problems.

Our Power Quality team can provide your facilities and systems with a Power Quality site audit to identify the issues that are affecting your bottom line. At Elion our team work to find out the exact cause of these problems by accurately measuring AC RMS voltages up to 480V (phase to neutral) or 830V (phase to phase) for two-wire, three-wire and four-wire networks. Alternating RMS currents up to 3000 A RMS Frequency of 50Hz networks (10Hz to 70Hz)Active, reactive and apparent power per phase and their aggregate. Harmonic Distortion (up to the 50th harmonic, anaverage value of any parameter calculated over a period running from 1 sec to 2 hours.

Power disturbances (swells, dips and interruptions, overrun of power and harmonic thresholds) are recorded and time stamped. Detection of transients and recording of the associated waveforms.
