Whether used for substation field verification, sensor commissioning, or laboratory training, the MOEORW-WPDM12 provides an indispensable asset for predictive maintenance in power grids.

📡 Ultimate Multi-Channel Output: Features dedicated physical ports for UHF, HF, TEV, AE, and background noise simulation.

⏱️ Ultra-Fast Rise Time: Delivers high-speed simulation pulses with a rise time of ≤300 ps, mimicking actual steep-fronted insulation breakdown pulses.

🔋 Dual-Power Versatility: Supports both standard AC 220V power and built-in 12.6V lithium-battery operation for unrestricted field testing.

🎛️ Intelligent Phase Synchronization: Equipped with internal and external synchronization choices (Internal 50Hz frequency adjustment available).

📶 Wireless Expandability: Features built-in WIFI capabilities to support future smart communication and wireless controls.

This universal calibration tool is optimized for global power utilities, testing laboratories, and high-voltage equipment manufacturers.

Key Global Application Scenarios:

PD Detector Calibration: Verifying online and offline PD monitoring systems according to international IEC 60270 frameworks.

Substation Asset Verification: Simulating real defects to test the accuracy of sensors mounted on GIS (Gas Insulated Switchgear), power cables, transformers, and switchgears.

Smart Grid Diagnostics: Field troubleshooting using localized high-frequency, ultrasonic, and transient earth voltage (TEV) methods.

R&D and Academic Training: Serving as an artificial PD source for high-voltage engineering labs and quality inspection centers.

The MOEORW-WPDM12 accurately replicates the 4 major types of insulation defects and background noise patterns, allowing users to easily train AI diagnostic algorithms or verify phase-resolved partial discharge (PRPD) patterns:

• Corona Discharge : Generates concentrated pulses primarily on the negative half-cycle of the voltage period.
• Surface Discharge : Simulates asymmetrical pulses, where one half-cycle features significantly larger pulse amplitudes than the other.
• Floating Electrode Discharge: Replicates stable, identical symmetrical pulses appearing evenly in the 1st and 3rd quadrants.
• Void / Internal Discharge: Simulates unequal amplitude pulses across a period, maintaining general symmetry in the 1st and 3rd quadrants.
• Background Noise: Outputs stable, non-power-frequency-correlated background noise with a specific repetition rate to test the anti-interference filters of PD meters.

UHF Channel Testing: Use a BNC-to-N cable to connect the rear UHF port to the UHF sensor. Place the PD detector's sensor adjacent to the test fixture's sensor to verify UHF responsiveness.

HF Channel Testing: Use a BNC-to-Alligator Clips cable. Short-circuit the clips and pass them through the High-Frequency Current Transformer (HFCT) of your PD meter to inject simulation pulses.

TEV Channel Testing: Connect the unit to the specialized TEV test fixture using a BNC-to-N cable. Press the PD meter's TEV sensing face firmly against the designated "TEV Test Area" on the fixture box.

AE (Acoustic/Ultrasonic) Testing: Connect the BNC-to-M5 cable to the ultrasonic transducer. Secure both the simulator's transducer and the PD meter's AE probe onto the fixture panel using silicone gel to ensure seamless acoustic coupling.

The MOEORW-WPDM12 is strictly engineered, manufactured, and inspected according to global electric power grid directives and electronics measurement criteria:

IEC 60270 Compliant: Aligns with international standards for high-voltage partial discharge measurements.

GB/T 6593: Meets quality inspection rules for electronic measuring instruments.

High-Voltage Grid Testing Guidelines: Modeled after standard field application guides for High Frequency (HF), Ultra-High Frequency (UHF), and Ultrasonic (AE) live-line detection technologies on GIS, transformers, and cables.
