80 percent of power quality problems involve sags, or temporary reduction in voltage. Equipped with a 5 kW and 250 kW simulators, AEP can precisely simulate any type of sag and determine how your equipment will respond by using the portable three-phase 20,000-watt sag/surge generator and the hand-held power harmonic analyzer.

• Portable Three-Phase 20,000 Watt-Sag/Surge Generator: The sag/surge generator is a portable three-phase generator complete with an isolated data acquisition system. The generator has a variable duty cycle and can inject a sag/surge from 0 degrees to 360 degrees. This device is a complement to the arbitrary waveform generator and will be used for “on-site” power quality investigations and to generate ITIC curves on PLCs, ASDs and other equipment powered by switching power supplies.
• Hand-held Power Harmonic Analyzer: This piece of equipment is used in conjunction with the sag/surge machine for “on-site” power quality investigations. The analyzer measures harmonic content, power, power angle, volts and amperes. The analyzer provides an excellent power quality toolbox in a small package.
