FAQ
1. What is a power frequency withstand voltage test set?
A power frequency withstand voltage test set is high voltage testing equipment used to verify the insulation strength of electrical equipment, components, and insulating materials under specified AC voltage conditions.
2. What is a high voltage test transformer used for?
A high voltage test transformer is used to generate the high test voltage required for dielectric withstand and insulation strength testing.
It can be used for testing equipment such as:
• Power cables
• Transformers
• Switchgear
• Circuit breakers
• GIS and other high voltage equipment
• Insulating materials
• Electrical components
• CTs and PTs
• Other high voltage electrical equipment
The required test voltage and capacity depend on the equipment under test and the applicable test procedure.
3. What is the difference between an AC hipot tester and a high voltage test transformer?
An AC hipot tester is a complete test system designed to perform a dielectric withstand test, while a high voltage test transformer is the component that generates the required high voltage.
