All You Need to Know About Switchgear – What Is It, How ... of Switchgear HV: High Voltage Switchgear. The power system controls voltage over 36KV, which is known as high voltage. As the voltage is usually high, the arcing generated during transitioning operation is also high. Therefore, additional care is taken during manufacturing of high voltage switchgear.Author: Nick Grogan[email protected]
