Products Description
Our Handheld Partial Discharge Tester displays amplitude, waveform, phase, PRPS, and PRPD views for field diagnosis. Internal, wireless, or optical synchronization can align the result with the power-frequency phase.
Technical Principle
Sensors capture high-frequency, UHF, ultrasonic, or transient-earth-voltage signals produced by insulation discharge. The monitoring unit filters interference, extracts pulse features, compares phase-resolved patterns, and records amplitude and repetition trends for alarm and diagnosis.
Product Features
The Handheld Partial Discharge Tester places four live-discharge methods in one portable instrument. Multiple graph types help compare amplitude, phase pattern, pulse sequence, and waveform. Several synchronization methods support different field-access conditions. Stored equipment information and test records support structured inspection routes.
Operating Conditions
The product shall be installed and operated within the ratings stated in the technical parameters. Key site requirements include: frequency phase.. Keep the installation area clean, adequately ventilated, free from corrosive gas and severe vibration, and provide the specified grounding, clearance, and power quality.
