Partial Discharge (PD) Tester

The tester utilizes advanced RF, high-frequency, and weak signal processing technologies to develop a unique high-frequency partial discharge detection solution. It employs high precision digital signal processing chips to accurately capture the partial discharge signals of the products under test. It is suitable for local discharge test of new energy main drive motor of industrial motor.

Measurable: It provides the industry's exclusive PD-UHF measurement and testing solutions.

Multi-function: One device can support both inter turn PD (DC-PD) and withstand voltage PD (AC-PD) at the same time.

Multi-channel: It supports multi-channel switching, and automatically completes all tests at one wiring to meet the test needs of multi-winding motors.

High performance: It adopts a high signal-to-noise ratio identification algorithm to achieve high sensitivity testing of partial discharge.

High reliability: It has undergone strict working condition tests and millions of tests in complex environments.

High stability: The test results are stable and not easily affected by the environmental conditions of the production site multi-interface.

The system supports USB, RS232, LAN and other interfaces, supports PLC communication, TCP/IP network protocol, etc., supports MES docking customization, database upload, etc.

Test items: PDIV, RPDIV, PDEV, and RPDEV

IPDIV: It refers to the lowest voltage when the test voltage gradually increases from the lower voltage that does not produce partial discharge, and the partial discharge amount exceeds a certain specified value in the test.

IRPDIV: It refers to the lowest voltage when the test voltage gradually increases from the lower voltage that does not produce partial discharge, and the partial discharge amount in the test repeatedly exceeds a specified value.

IPDEV: It refers to the maximum voltage when the test voltage gradually decreases from the higher value exceeding the initial voltage of partial discharge, and the partial discharge amount in the test is less than a specified value.

IRPDEV: It refers to the maximum voltage when the test voltage gradually decreases from a higher value exceeding the initial voltage of partial discharge, and the partial discharge amount is repeatedly less than a certain specified value in the test.
