Over 75 Years of Trusted Solutions for Utility Distribution Systems
Fisher Pierce has been a trusted name in utility automation, providing innovative fault detection and capacitor control solutions that enhance grid reliability and operational efficiency.
As part of ABB Installation Products division's comprehensive portfolio of utility products, Fisher Pierce solutions are engineered specifically for the demanding requirements of public power and investor-owned utilities. The brand focuses on two critical areas: fault location and power factor correction essential for maintaining reliable, efficient distribution systems.
Fisher Pierce products are designed to withstand harsh outdoor environments while providing accurate, actionable intelligence that helps utility crews respond faster to outages and optimize system performance. From overhead fault indicators to sophisticated capacitor bank controllers, every product reflects decades of utility-focused engineering expertise.
Intelligence That Reduces Outage Duration
Fisher Pierce fault indicators revolutionize how utilities locate and respond to distribution system faults. These intelligent devices detect fault current and provide visual or remote indication of fault passage, dramatically reducing the time crews spend patrolling lines to locate problems. Advanced models integrate with SCADA systems, providing real-time fault location data that enables faster restoration and improved customer satisfaction.
The capacitor controller product line optimizes reactive power management through intelligent switching algorithms that respond to system conditions. By automatically adjusting capacitor banks based on voltage, current, temperature, and time-of-day parameters, Fisher Pierce controllers help utilities reduce losses, improve voltage profiles, and defer costly infrastructure upgrades.
Engineered for Utility-Grade Performance
Every Fisher Pierce product is built to utility specifications, with ruggedized enclosures, extended temperature ratings, and proven reliability in the field. The fault indicators feature self-powered operation, eliminating the need for external power sources or battery maintenance. Capacitor controllers incorporate surge protection, lightning immunity, and fail-safe operation to ensure continuous performance.
Integration capabilities allow Fisher Pierce devices to communicate with existing utility automation systems through multiple protocols, making them ideal for both new installations and system upgrades. The modular design philosophy ensures that utilities can start with basic functionality and expand capabilities as their automation strategies evolve.
