PD Detector Calibrator
PD2024 Partial Discharge Detector Calibrator: Comprehensive Calibration Solution
Professional-grade calibrator for validating partial discharge (PD) testers with nanosecond-level precision and multi-parameter verification per IEC 60270 standards.
Core Calibration Functions
Nominal Band & Chopped Frequency Test - Verifies PD tester's frequency response accuracy
Charge Measurement Nonlinear Error Test - Validates apparent discharge (q) measurement linearity
Polarity Response Asymmetry Test - Checks ±impulse measurement consistency
Range Shift Error Test - Ensures stable calibration across measurement ranges
Low-Repeatability Impulse Response Test - Confirms detection threshold reliability
Impulse Resolving Time Test - Measures PD tester's temporal discrimination capability
Detection Sensitivity Test - Quantifies minimum detectable discharge level
Long-Term Stability Test - Evaluates instrument drift over continuous operation
Measurement Repeatability Test - Assesses result consistency across multiple cycles
