Partial discharge testers are designed with different considerations in system architecture, human-computer interaction, and portability, depending on the application scenario and functional requirements.
Digital partial discharge detection systems typically feature fully automatic calibration, automatic synchronization, automatic voltage recording, and automatic measurement, saving, and playback functions. They can measure various partial discharge parameters specified in IEC-270. The system supports single-channel and dual-channel testing, offers multiple view display modes such as sine wave and dot matrix, and includes digital filtering and interference suppression functions.
Handheld and multi-functional handheld partial discharge detectors are designed with portability in mind, featuring a compact structure and light weight, suitable for on-site inspections. Some models typically integrate ultrasonic and transient ground voltage (TEV) sensors into the main unit for integrated detection. To adapt to outdoor environments, the instruments often use color touchscreens, ensuring clear display even in strong light.
In terms of user interface design, the instruments often use large-area oscilloscope tubes or color touchscreens for clear display and support flexible programming and control software upgrades. Some handheld models are equipped with a function self-test device to verify the instrument's operating status before measurement.
