What is a DC Hipot Tester
A DC Hipot Tester (full name: Direct Current High Potential Tester) is an instrument used in the electrical industry to test the insulation performance of electrical equipment. Its main functions are:
- To test whether electrical equipment or insulating materials can withstand high DC voltage without breakdown.
- To check if the product’s insulation strength meets safety standards.
- To provide safety verification and prevent leakage or insulation failure during operation.
In other words, it helps determine whether the insulation of a device is “strong enough” to handle its rated voltage safely.
Working Principle
The basic working principle of a DC Hipot Tester is as follows:
1.Apply high DC voltage – The tester gradually increases DC voltage to the device under test (DUT), such as motor windings, transformers, or switchgear.
2.Monitor leakage current – The tester measures the current that leaks through the insulation.
3.Determine pass/fail:
- Leakage current within the allowed range → insulation passes
- Leakage current exceeds the limit → possible insulation defect
4.Record or alarm – Modern testers provide digital displays and automatic data recording.
Formula: DC Hipot testing typically monitors leakage current using:
Where:
- I = leakage current
- V = applied test voltage
- R = insulation resistance
The leakage current indirectly indicates the insulation quality.
