Bushing Potential Devices

Parts Super Center source OEM bushing potential devices and accessories used for voltage monitoring, protection, and diagnostics in high-voltage transformer systems. These devices provide a safe, low-voltage signal proportional to system voltage, enabling reliable operation of relays, meters, syncroscopes, and monitoring equipment in substations, utilities, and industrial power systems. Bushing potential devices are critical for monitoring transformer insulation performance and detecting early-stage faults. Whether supporting substation maintenance, grid reliability, or industrial power systems, these components help ensure safe operation and extend equipment life.

Bushing potential device units and shielded cables designed for transformer bushings and monitoring systems. Ideal for use in power transformers, distribution networks, and high-voltage applications requiring accurate signal output and insulation monitoring. Available Features & Specifications: Compatible with GE and legacy transformer systems, including KA-108 bushing potential devices. Options include passive and active voltage outputs, typically ranging from 1–100V AC or analog/digital signal outputs for SCADA, relays, and metering systems. Designed for 50/60 Hz operation with high dielectric strength, low noise signal transmission, and compatibility with various cable lengths and termination types.
