Series 078 Power Factor Meters

The Series 078 Power Factor Meters from Spectrum Industries provide a dependable and accurate way to monitor the power factor in 3-phase electrical systems. Housed in a robust 4½" analog panel design, these meters are ideal for continuous monitoring in industrial plants, commercial buildings, and utility environments where maintaining power quality and efficiency is critical.

Available for both balanced load 3-phase 3-wire and 4-wire systems, the Series 078 meters offer a clear, easy-to-read scale with a full 90° deflection, allowing operators to instantly assess the power factor of a system—from leading to lagging conditions. This visibility helps ensure that corrective actions, such as power factor correction with capacitors, can be implemented promptly to reduce energy waste, avoid penalties, and improve system performance.

Engineered for long-lasting reliability and precision, the Series 078 meters feature a rugged, high-impact case and proven analog movement. Whether used in control panels, switchgear, or monitoring stations, these meters offer a trusted solution for real-time power factor analysis.
