Product Introduction
The MOEORW-WNAEC Non-Contact Ultrasonic Partial Discharge Detector Calibration System is a professional-grade testing rig engineered to evaluate, verify, and calibrate the performance metrics of handheld or portable ultrasonic partial discharge (PD) detectors. Developed from extensive on-site live inspection experience, this system ensures that your PD diagnostic instruments maintain peak accuracy, linearity, and repeatability over time.
The system provides fully automated, software-driven testing procedures that meet rigorous power grid engineering requirements. By utilizing an integrated acoustic actuator and precise position control, it guarantees high-fidelity evaluation of grid assets' testing tools, maximizing the reliability of early-stage insulation fault detection.

FAQ
Q1: What regulatory standards does this calibration rig comply with?
A: The system fully supports major electrical industry benchmarks, including industry-recognized standard DL/T 1416-2015 (General technical conditions of partial discharge tester by ultrasonic method) and enterprise power grid technical specifications.
Q2: Can it calibrate multichannel partial discharge instruments?
A: Yes. The software features a dedicated Channel Consistency Test module that evaluates both amplitude deviations and time-delay synchronization across multiple channels concurrently.
Q3: How does the system protect against ambient acoustic interference during testing?
A: The automated process runs a Background Noise Baseline Check before the actual sensitivity or linearity routine begins. The system alerts the technician if environmental room noise spikes past 40 dB SPL, ensuring ultra-clean calibration data.
Q4: In what formats are calibration certificates and raw data exported?
A: The measurement suite records internal historical database logs, which can be searched at any time. Final formal documentation is exported as fully formatting Microsoft Word (.docx) files for easy editing and custom branding.
