Product Overview
The MOEORW-GUC UHF Partial Discharge Calibration System is a highly integrated, professional-grade platform engineered specifically for verifying, benchmarking, and calibrating the performance of Ultra-High Frequency (UHF) partial discharge (PD) detection instruments.
Integrating state-of-the-art signal synthesis, high-precision measurement topologies, and automated evaluation algorithms, this system provides comprehensive and traceably precise assessment for UHF detection equipment, guaranteeing operational reliability in structural health monitoring and live field inspections.
The system's core parameters fully comply with utility standard frameworks, including State Grid Q/GDW 11304.8-2019 (Technical Specifications for Energized Test Instruments of Power Equipment - Part 8: UHF Partial Discharge Detector) and industry standard DL/T 1630-2016 (Technical Specification for UHF Partial Discharge Detection in Gas Insulated Metal-Enclosed Switchgear). It serves as a benchmark metrology solution to support data-driven asset management and precise condition assessment for smart grids.
Application
Grid Asset Metrology & Calibration Laboratories: Used by national, provincial, or third-party electrical metrology institutes to periodically calibrate and certify portable or online UHF partial discharge diagnostic tools.
GIS / GIL Quality Assurance Testing: Serves equipment manufacturers and field testing crews to verify the absolute sensitivity of internal or external UHF sensors installed on Gas Insulated Switchgear (GIS) and Gas Insulated Lines (GIL) before commissioning.
PD Diagnostic Instrument Development & QA: Used by high-voltage test equipment R&D departments to baseline signal capture logic, train AI defect-recognition classifiers (pattern recognition algorithms), and test anti-jamming filters against multi-frequency environmental noise.
Substation Commissioning and Preventive Maintenance: Validates field-deployed (live inspection) instruments, ensuring high signal-to-noise ratios (SNR) and standardized data comparability when diagnosing high-risk insulation faults.
All-in-One Structural Integration: Features a fully integrated console design. Users complete the physical wiring matrix just once, and the software automatically runs all verification items without manual cable swapping.
Comprehensive Multi-Dimensional Validation: Fully capable of measuring sensor average effective height (Heff), input detection sensitivity, dynamic response ranges, PD pattern classification accuracy, and long-term operational stability.
Pure Signal Pathway via Pneumatic Switching: Employs pneumatic-driven switches instead of traditional electromagnetic relays. Coupled with an advanced dual-layer aluminum alloy shield, it isolates structural control signals from high-frequency test paths, maintaining unmatched signal integrity.
Smart Verification Engine: Powered by a customized C/S architecture application. Features parametric waveform editing (manual canvas drawing or spectrum/image importing), automatic metric computation, threshold pass/fail judgment, and automated standardized PDF report generation.
Robust Multi-Mode Power Architecture: Equipped with a smart-switching dual power system. Seamlessly transitions between standard utility power (220V/50Hz) and an onboard internal battery pack, ensuring reliable field deployment in harsh switchyard conditions.
