In any facility symptoms can present themselves such as; a computer locks up, lights flicker, or a motor overheats. They’re often considered minor or even normal—assumed to be the result of normal wear, minor bugs, or equipment aging. But too often, the real cause is poor power quality.
Power quality problems can be serious and very costly:
• Data loss
• Products damaged during production
• Excess energy consumption
• Additional expense in maintenance, equipment repairs, and equipment replacement
If you have experienced any of the top five warning signs, you could be the victim of one or more of these repeat offenders:
Voltage dips and swells—typically caused by large loads starting up or shutting down; can damage computers, electronic controls, and lamps
Harmonic distortion—alteration in current frequency cycles; can cause heat-related problems in motors and transformers, plus problems with circuit breakers, fuses, and relays
Voltage unbalance—significant differences in phase voltages of more than 2 %; typically causes motors and transformers to overheat
Flicker—cyclic voltage dips; causes lights to flicker: more a threat to employee productivity than to equipment
Transients—brief, sharp voltage increases caused by equipment switching on or off, capacitor switching, and lightning; can lock up computers, burn out circuit boards, and damage electrical insulation
These conditions are usually within the facility itself and therefore your responsibility, not the electrical supplier’s.
To help you identify them, fix them, and avoid them in the future through proper prevention and maintenance, consider the Fluke 1735 Three-Phase Power Logger.
With the Fluke 1735 Three-Phase Power Logger you can conduct voltage, current and power studies for determining existing loads. The Logger is also a general-purpose power quality investigative tool that reveals the quality of voltage supply at any point in a distribution network.
