ZJ302-40.5 Insulator Sensor: Technical Overview The ZJ302-40.5 Insulator Sensor is a specialized device designed for monitoring the condition of high-voltage insulators in power transmission and distribution systems. Operating at a rated voltage of 40.5 kV, this sensor plays a critical role in ensuring the reliability and safety of electrical infrastructure by detecting potential insulator failures, contamination, or degradation in real time. Key Features 1. High-Voltage Compatibility: The sensor is engineered for use in 40.5 kV systems, making it suitable for medium-voltage applications such as substations, overhead lines, and switchgear. 2. Contamination Detection: It identifies conductive pollutants (e.g., dust, salt, or moisture) on insulator surfaces, which can lead to flashovers or short circuits. 3. Leakage Current Monitoring: By measuring leakage currents across insulators, the sensor helps predict insulation breakdowns before they occur. 4. Temperature and Humidity Resistance: Designed to operate in harsh environments, it withstands extreme temperatures and high humidity levels. 5. Non-Intrusive Design: The sensor integrates seamlessly with existing insulator strings without disrupting electrical performance. 6. Real-Time Data Transmission: Equipped with communication interfaces (e.g., RS485 or wireless protocols), it transmits data to centralized monitoring systems for analysis. Applications - Transmission Lines: Monitors insulator health on towers to prevent outages. - Substations: Detects contamination or cracks in post insulators. - Renewable Energy: Ensures insulator integrity in solar/wind farms with high exposure to environmental stressors.
