Surge Impulse Voltage Tester

Our company's fully automatic insulation material withstand voltage breakdown tester is manufactured according to the national standard GB1408.1-2006 "Electrical Strength Test Method for Insulation Materials". Its function can also be called an electrical insulation strength tester or dielectric strength tester. Its working principle is: a voltage higher than the normal operating voltage is applied to the insulator of the tested equipment for a specified period. If the applied voltage only produces a very small leakage current, the insulation performance is good. This equipment adopts advanced microelectronic chip processing technology, touch screen control, and host computer operation, making it simple and clear to operate. The testing system consists of three modules: a programmable power supply module, a signal acquisition and conditioning module, and a computer control system. After all test parameters are set, the test is performed automatically without manual intervention.

1. The device is operated and controlled via a 7-inch touchscreen.
2. If curve analysis is required, a computer can be provided for data and curve recording only, without controlling the equipment. This avoids the need for experimenters to switch between the computer and the equipment, making it more user-friendly.
3. The equipment has a test parameter memory function. The same test conditions do not need to be set for each test, and the last test setting parameters will still be remembered even after power failure.
4. The experimental interface is simple and clear, and easy to understand.
5. The control panel is simple, the functions are clearly labeled, and the operation is easy.
6. It can record 100 experimental data points simultaneously, with 10 experimental records per page, facilitating comparative analysis of experimental data.
7. The equipment test interface uses a real-time display method, which makes it more convenient to watch the test process.
8. This instrument has multiple safety measures to ensure the personal safety of the operator .

• Door limit protection: If the door is not closed, the equipment will not respond even if the experiment starts at the power-on point.
• Voltage Zero Protection: If the power is suddenly cut off during the experiment, the voltage will automatically return to zero after the next power-on, ensuring that the initial voltage is zero .
• Overvoltage protection: The termination voltage can be set by software to ensure that if an abnormal voltage rises to the specified voltage during the voltage boosting process, the voltage will automatically terminate and return to zero .
• High-voltage mechanical limit: If the software system loses control and the voltage continues to rise, the system will indicate that the upper limit has been reached after the high-voltage limit is reached .
• There is a running indicator light. You can determine whether it is running by observing the status of the indicator light .

This device is mainly suitable for testing the breakdown strength and withstand voltage of solid insulating materials (such as plastics, rubber, laminates, films, resins, mica, ceramics, glass, insulating varnishes, etc.) under power frequency or DC voltage. It is designed and manufactured for high-voltage breakdown testing in the power electronics industry, machinery industry departments, research institutes, military research, and insulating material production units.
