GENERAL INFORMATION
What is High Voltage Test?
High Voltage Testing is done as a way to check the effectiveness of the insulation of the device to ensure it will operate safely during rated electrical conditions.
Why is High Voltage Test Done?
It is a high voltage test during maintenance programs to demonstrate that equipment can withstand surge voltages during operation. An overvoltage is usually applied between the primary and secondary of the transformer or between the secondary and ground for 60 seconds.
