Metravi ZNT-34 Relay Test Set

The Metravi ZNT-34 relay and protection test set is a high-performance three-phase testing instrument designed for accurate commissioning, calibration, maintenance, and troubleshooting of protective relays, control circuits, and electrical panels in substations, power plants, industries, and utility systems. Built for professional relay testing applications, this robust unit operates on 415V ±10 percent, 3 phase, 4 wire, 50Hz AC input and provides flexible output test current taps of 0, 1, 5, 10, 25, and 50A with fine 0 to 100 percent resolution in each tap. It also features an isolated 0 to 240V DC source with maximum available current of 1A, making it suitable for a wide range of simulation and functional test requirements. With phase angle variation from 0 to 360 degrees in the current circuit, precise time measurement capability, rated maximum burden of 500VA per phase for test current, and 150VA per phase for test voltage, it delivers dependable performance for advanced relay verification. Metravi ZNT-34 is an ideal solution for protection testing, relay timing checks, commissioning work, and preventive electrical maintenance. Available on EnvMart, these Electrical Power Testing instruments are essential for monitoring voltage, current, power factor, and energy consumption—crucial for electrical audits, load analysis, and system diagnostics. Metravi Electrical Power Testing equipment is trusted for its precision, rugged design, and advanced features, making it a top choice for energy professionals and field engineers.
