Product Overview
This product can be widely used in the partial discharge detection and temperature rise detection of power systems, including the insulation state and temperature rise detection of equipment as high-voltage switch cabinets, ring main units, transformers (including dry-type transformers), etc., and the health of electrical equipment is measured by the following:
Partial discharge intensity detection: The discharge signal within one power frequency cycle is measured, and the maximum value (dB) in the discharge pulse sequence is used to represent intensity of partial discharge.
Partial discharge frequency detection: The discharge signal within one power frequency cycle is measured, and the discharge pulse is extracted and the frequency of partial discharge is according to the number of discharge pulses.
Temperature rise detection: The temperature condition of the equipment is checked by infrared thermal imaging, and the current maximum and minimum temperatures of the are understood.
Environmental noise detection: Environmental noise is collected by the built-in high-precision microphone, and the subtle sounds that may exist in the current environment, such mechanical parts loosening, are analyzed.
☀ Different sensors are selected to achieve different functional detection;
☀ Humanized human-machine interface for convenient data management of different devices;
☀ Builtin ultrasonic sensor and transient ground voltage (hereinafter referred to as TEV) sensor, external high-frequency current sensor (HFCT), ultra-high frequency (UHF), contact ultrasonic sensor (AE), can take different forms to show the detection results, including PRPD and PRPS display results.
☀ The-invasive testing method is used, and the test does not need to be powered off during the test, and there is no need for additional configuration of high voltage source, which more convenient to use than the traditional pulse local discharge tester;
☀ The test band range is applicable to the detection principle of various frequency bands
