For example, more than likely your business uses microprocessor-based systems. If these devices are continually affected by voltage disturbances, they can be damaged and cause a shutdown. The downtime will result in financial losses.

Power quality monitoring should be considered an integral part of any maintenance program. Continual monitoring is an easy way to determine whether your power quality is adequate. It can also help predict your future power quality requirements.

Common Questions about Power Quality

Why Not Use a Meter and Check?

Determining whether a power quality problem exists is very difficult with traditional meters and scopes. The difficulty is that they cannot tell you what has happened in the past. In addition, power quality problems occur faster than the blink of an eye. Many power quality problems result from various types of incompatible equipment operating simultaneously. Equipment such as air conditioning units, heavy machinery and office equipment are the major culprits. Because buildings are wired with numerous circuits, traditional methods of pinpointing the source of power conflicts are almost useless. Data logging can tell you where your problems occur, at what time, and how often.

Why Not Buy a Protection Device?

Protection devices such as constant voltage transformers, UPS’s and transient protection devices may not provide the correct protection for the types of problems that are occurring on your power line. The only way to know what type of protection device is required is to analyze the nature of the power line disturbances.

For instance, there are many UPS’s at different price ranges, each claiming to offer some protection. But some UPS’s cause more problems than they solve. Outfitting your entire electrical environment with power quality enhancing devices could cost a large amount of money not to mention extended downtime. Data logging your electrical environment before and after choosing a correction method is the only way to find out whether you have chosen the best method.
