GIS Partial Discharge Simulation Tester

A: It's a specialized device that simulates partial discharge (PD) in Gas-Insulated Switchgear (GIS)-critical power equipment used in substations. Its main role is to test and calibrate PD detection tools (e.g., PD sensors, analyzers) to ensure they can accurately identify real PD faults in GIS (e.g., internal defects, insulation breakdown). It also helps train engineers on PD detection in GIS systems.

A:

It covers common GIS partial discharge scenarios to mimic real-world defects:​

Corona discharge (e.g., from sharp metal edges in GIS).​

Surface discharge (e.g., dirt or moisture on GIS insulation surfaces).​

Internal discharge (e.g., tiny gaps in GIS insulation materials).​

Floating potential discharge (e.g., loose metal parts in GIS).

A:

PD Signal Range: Simulates PD magnitudes from 10 pC to 10,000 pC (covers typical GIS PD levels; 1 pC = 10⁻¹² coulombs).​

Output Voltage: Supports AC voltage up to 10 kV (to create realistic PD conditions).​

Frequency: 50 Hz/60 Hz (matches grid frequency for authentic simulation).​

Signal Stability: PD magnitude error ≤ ±5% (ensures reliable calibration of detection tools).

A:

Cables/Connectors: Wipe with a dry cloth after use; check for cracks (replace if damaged-loose connectors cause signal loss).​

Touchscreen: Clean with a soft, damp cloth (avoid harsh cleaners to prevent scratches).​

Storage: Keep in a dry, cool place (humidity ≤ 80%, temp 5°C–35°C) when not in use-avoid dust or moisture.​

Battery (if portable): If it has a built-in battery, charge it fully every 3 months (prevents battery degradation).
