ZJ-101-21 12KV Voltage Measurement Sensor – Technical Overview The ZJ-101-21 12KV Voltage Measurement Sensor is a high-precision, non-contact device designed for accurate voltage monitoring in medium-voltage (MV) power systems. It is widely used in substations, industrial plants, and renewable energy installations to ensure safe and efficient operation by providing reliable voltage data for control, protection, and metering applications. Key Features 1. High Voltage Compatibility The sensor is rated for 12KV systems, making it suitable for medium-voltage networks. It employs advanced insulation materials and a robust design to withstand high electric fields while maintaining measurement accuracy. 2. Non-Contact Measurement Utilizing capacitive or resistive voltage division principles, the sensor measures voltage without direct electrical contact with the live conductor. This ensures safety, reduces maintenance needs, and minimizes interference with the primary circuit. 3. High Accuracy & Stability The device delivers ±0.5% or better accuracy across a wide temperature range (-40°C to +85°C). Its low drift characteristics ensure long-term stability, even in harsh environments. 4. Compact & Lightweight Design The sensor features a compact form factor, enabling easy integration into switchgear, circuit breakers, or overhead line installations. Its lightweight construction reduces mechanical stress on supporting structures. 5. Wide Frequency Response With a broad bandwidth (typically 50Hz–1kHz), the sensor accurately captures fundamental and harmonic voltages, supporting power quality analysis and grid diagnostics. 6. Output Options Standard outputs include analog signals (e.g., 0–5V, 4–20mA) or digital interfaces (e.g., RS-485 with Modbus protocol), ensuring compatibility with SCADA systems, relays, and smart grid applications. 7. Environmental Resilience Designed for outdoor or indoor use, the sensor meets IP65/IP67 ingress protection ratings and resists humidity, dust, and chemical exposure. Applications - Grid Monitoring: Real-time voltage measurement for substation automation. - Renewable Energy: Integration into solar/wind farms for voltage regulation. - Industrial Power Systems: Overvoltage/undervoltage protection in factories. - Smart Metering: Energy data acquisition for billing and load management. Safety & Compliance The sensor complies with international standards such as IEC 61869, IEEE C57.13, and undergoes rigorous testing for dielectric strength, impulse withstand, and EMI immunity. Conclusion The ZJ-101-21 12KV Voltage Measurement Sensor offers a reliable, maintenance-free solution for medium-voltage monitoring.
