The Right Selection - UPS and Harmonics

Uninterruptible Power Supply or commonly known as UPS, thought to be designed for emergency power supply, is a very common device in India. However, along with emergency power supply, it is also now used to correct other power quality problems. An UPS can be used to solve power quality issues such as over voltage, under voltage, constant frequency, noise and voltage dips. For power supply to critical equipments, UPS is also used as an isolated mode of power supply where common mode noise needs to be filtered out and protect the equipment from neutral related faults or issues in the main supply network.

This case study presents a comparison of two UPS on test bench. The test was carried out to demonstrate low harmonics UPS.
