Advantages of DC Hipot Tester

Portability and Power: DC Hipot testers are highly portable for their voltage rating. They require a much lower power input to generate high test voltages, making them ideal for field testing of high-capacitive objects like long cables.

 

Detection of Specific Faults: They are excellent for pinpointing specific insulation weaknesses, such as concentrated punctures or tracking, as the steady voltage will cause a breakdown at the fault point.

 

Eco-Efficient Design: The designers specified an energy-efficient concept powered by components with power-saving features, which cut operations costs and limit the environmental footprint.

 

User-friendly interface: The DC hipot tester is equipped with an interface that is not only intuitive but also provides high-resolution display and visualization of real-time data and diagnostics.

Usage Requirements

 

 

Safety precautions must be emphasized with a DC hipot tester because the safety of the operator and equipment depends upon them. Check to see that the tester is grounded, and keep everybody at a safe distance during the test. Wear PPE: insulating gloves, safety glasses, and so forth. Ensure that the equipment to be tested is de-energized and isolated from any power supply. Get acquainted with the voltage level and test procedures for testing the equipment.

Q: What about the transportation?

A: Usually we take door to door express delivery ,cause it's more convenient and fast.

Q: What is a DC hipot test?

A: A DC hipot tester, also known as a high potential tester, is an electrical device used to check the insulation against electrical hazards and the integrity of electrical equipment and components. To test for operational voltage, this ứng dụng applies a very high DC voltage to the insulation of devices.

Q: What is the difference between AC and DC hipot?

A: DC hi-pot tester provides a more accurate reading of the leakage current as it only reads real current. AC hipot tester, on the other hand, measures total current and does not provide accurate leakage current measurement.

Q: What is the leakage current for DC hipot?

A: The test waveform, whether DC or an ac sine wave is also typically specified. What constitutes a failure? Hipot test failure is when the leakage current exceeds a specified limit or rapidly increases in an uncontrolled manner, or if arcing is observed. Typical leakage current limits range from 0.5 to 20 mA.

Q: How does a DC hipot tester work?

A: When a DC hipot tester is operated, a high DC voltage is generated and applied across the insulating layer of the device under test (DUT). The tester then measures the leakage current flowing through the insulation to the earth. If the leakage current reaches a certain threshold level, it indicates that the insulation is compromised.

Q: How do you choose the right DC hipot tester?

A: There are several factors to consider when selecting the right DC hipot tester for your requirements. First, choose one that fits within the voltage range you will be working with and has the required features for your applications. Apart from adjustable voltage settings and digital readouts, a safety auto-shutdown should be included. Since portability matters a lot for field testing, keep it in mind.

Q: How often should you have DC hipot testing done?

A: The frequency of DC hipot testing depends on various factors, such as industry standards, usage of equipment, and environmental conditions. Usually, DC hipot testing must be done once a year or every six months for critical equipment or in harsh environments. Regular testing keeps the insulation in its best condition and also helps prevent premature failures from suddenly occurring.
