Power quality analyzer

The PA9Wireless power quality analyzer is designed for remote recording of electrical signals on low-voltage power lines. Because the analyzer incorporates a wireless modem, users can configure the unit remotely, view real-time data via the remote screen, and preview all recorded data without downloading the data. A large backlit LCD confirms setup information and real-time status, phasors, frequency, harmonics, harmonic power, voltage, current, per phase, total power/energy data, and minimums/maximums by phase.

Surge protector

The Rayvoss standalone surge protector is available in single-phase, split-phase, 3-phase wye, and 3-phase delta configurations. In addition, the device can be installed directly to the internal bus bars, eliminating the voltage drop across a fuse. According to the company, this ability also provides lower clamping voltages and eliminates voltage surge when a fuse opens. Operating voltages include 120, 249, 120/208Y, 240/415Y, 277/480Y, 347/600Y, 240D, and 480D.

Surge protector

The STV200/400K Series of surge protective devices (SPDs) offer surge current capacity of 200kA to 400kA per phase. According to the company, the SPD feature the industry's highest surge current repeatability, providing transient protection in all modes (L-N, L-G, N-G) and EMI/RFI filtering. The product also uses patented circuitry to monitor the status of all protection modes, including neutral to ground. Should protection be unavailable in any mode, the SPD's green LED will be extinguished, and the red LED will be illuminated. In addition, high isolation Form C dry contacts provide remote monitoring of suppression system failure, undervoltage, phase, and power loss. The standard enclosure is rated NEMA 12 with available options for NEMA 3R, 4, and 4X. Other options include a rotary disconnect, transient counter, and remote monitor panel.
