Megger SMRT 46R – Multi-Phase Relay Test System

• Three high-power current channels (60 A/319 VA) plus convertible voltages for six currents or four voltages.
• Smart Touch View Interface or integrated touchscreen for stand-alone manual and dynamic testing.
• Dynamic, transient, and GPS-synchronised end-to-end testing capability.
• IEC 61850 GOOSE and Sampled Values testing with optional hardware upgrade.
• Lightweight, portable design with high compliance voltage and flat power curve.

The Megger SMRT46R delivers powerful multi-phase testing in a compact, field-ready package. It combines three independent current amplifiers and four voltage channels that convert to six currents when needed. Consequently, it handles everything from simple overcurrent relays to complex three-phase impedance and differential schemes without additional hardware. Moreover, the intuitive onboard display and RTMS software enable rapid manual or automated testing, including transient playback and GPS end-to-end synchronisation. With IEC 61850 GOOSE and 9-2 LE sampled values support, the SMRT46R meets modern substation requirements while maintaining the rugged portability technicians expect. This versatile system reduces test time, improves accuracy, and eliminates the need for multiple instruments in the field.
