Dataset of 110 kV Circuit Breaker Coil Currents for Condition Monitoring: Normal Operation and Fault Diagnostics 核心 · 已核验

mxdsw8kse42q9k02

This dataset contains coil current signals of a typical 110 kV circuit breaker, designed for fault diagnosis and feature extraction research. The data covers both normal operating conditions and various simulated defects. The measurements were obtained using a specialized coil current emulator, the details of which are documented in the associated publication: Machine Learning-Based High-Voltage Circuit Breaker Defect Classification Utilizing Savitzky–Golay Filter (10.1109/TIM.2025.3604980).

Data Acquisition

Sensor: ACS712 Hall-effect current sensor.

Sampling Frequency: Approximately 6.1 kHz.

Dataset Structure

The dataset is provided in a XLS format where each row represents a single measurement. The first column indicates the operational state or defect type as follows:

Norm: Normal operation of the coil (Baseline).

Aux: Auxiliary contact defect.

Latch: Latch operation/mechanical defect.

VoltRes: Supply voltage defect (Resistive/Voltage drop).

Usage Note

Researchers utilizing this dataset are encouraged to refer to the main paper (DOI listed above) for a detailed explanation of the feature extraction techniques and the physical parameters of the emulator used to generate these signals. These signals are optimized for feature extraction and the development of predictive maintenance algorithms for high-voltage switchgear.
