Cable Section Pulse-Response Mapping for Partial Discharge Location

The cable section is divided into multiple segments along its length, with each segment assigned to a specific sensor. The sensor compares the detected partial discharge signal with stored reference signals for its assigned segments, enabling precise location determination without requiring multiple sensors at both ends.

Reference signals for different cable segments are pre-calculated and stored in memory before operation. When a partial discharge occurs, the sensor immediately compares the detected signal with these pre-stored references, eliminating the need for complex real-time calculations and enabling fast, accurate location determination.

Instead of relying on direct propagation time measurement which is affected by attenuation and dispersion, the system creates reference copies of partial discharge signals for different cable segments. The detected signal is compared with these reference copies to determine location, effectively compensating for signal degradation effects.

The system transforms the location determination problem from time-based measurement to signal pattern recognition. By comparing signal characteristics (amplitude, waveform shape) with pre-stored references instead of measuring propagation time directly, the system achieves both speed and precision.

Each sensor is assigned specific cable segments and stores reference signals only for its local segments. This localizes the signal processing and comparison operations, reducing the computational complexity at each sensor while maintaining overall system precision.

Each sensor independently performs signal comparison and location determination for its assigned segments using locally stored references. This self-service approach eliminates the need for complex centralized signal processing and coordination between multiple sensors.
