Multifunctional Handheld Partial Discharge Online Detector
Darui Electric recommends:
ZCPD-100Z Multifunctional Handheld Partial Discharge Online Detector can be used with transient earth voltage (TEV) sensors, contact ultrasonic sensors, non-contact ultrasonic sensors, broadband current transformers, and UHF sensors for online detection of partial discharge in high-voltage equipment such as transformers, high-voltage switchgear, GIS, cable joints, and generators. ZCPD-100Z Multifunctional Handheld Partial Discharge Online Detector is easy to carry, fast to measure, strong anti-interference ability, and convenient for field use.
Functional Features
1. ZCPD-100Z Multifunctional Handheld Partial Discharge Online Detector Shanghai Duanyi Electric uses transient earth voltage (TEV) combined with ultrasonic sensors to detect the magnitude of partial discharge in high-voltage switchgear, combining contact measurement and non-contact measurement (handheld ultrasonic receiving antenna), which can be qualitative and quantitative.
2. Uses broadband current transformers and contact ultrasonic sensors to detect the magnitude of partial discharge in transformers.
3. Uses contact ultrasonic and UHF sensors to detect the magnitude of partial discharge in GIS.
4. Uses broadband current transformers to detect the magnitude of partial discharge in cable joints.
5. For non-contact ultrasonic sensors, sound analysis can be performed through headphones.
6. Uses a color LCD screen to display discharge waveforms and magnitude, providing a more user-friendly and intuitive display.
7. Can display single-channel discharge waveforms and trend graphs, and can display dual-channel discharge waveforms.
8. Stores data and waveform screenshots for high-voltage equipment with discharge, facilitating future analysis and comparison.
9. Yellow, green, and red three-level warning values and discharge waveforms are displayed on the same interface for convenience and intuitiveness.
10. Easy to use, small size, light weight, and easy to carry.
11. No power outage is required during the detection process.
