Electronic voltage sensor bushings are precision-engineered components designed for real-time voltage measurement, superior electrical insulation, and optimized energy monitoring. Used in high-voltage equipment, they ensure stable signal transmission, extended durability, and reliable system protection.
Product Overview
The Electronic Voltage Sensor Bushing uses the capacitive voltage divider principle (U2/U1 = C2/C1) to provide stable and reliable low-voltage signals, which are used for online voltage measurement, metering, fault diagnosis, and protection of power grid equipment. The sensor utilizes low temperature drift, wide-band dielectric ceramic materials to ensure its precision under extreme temperatures (-40°C to +70°C) and various electromagnetic environments. The product is packaged using resin technology, ensuring that the ceramic capacitor and resin bond properly, which enhances product reliability and reduces procurement costs.
