Megger SMRT1, SMRT1D and SMRT1B – Single Phase Relay Test Systems

• High current/high power: up to 75 A / 400 VA rms with flat power curve.
• Operate standalone (on-board display or STVI) or with RTMS software.
• Supports IEC 61850 GOOSE and 9-2 LE sampled values testing.
• Voltage output: 0–300 V / 150 VA; convertible to current for differential relays.
• SMRT1B includes optional battery power for true field portability.
• Saves results to internal memory or USB for reporting

 

The Megger SMRT1 series includes the SMRT1 with Smart Touch View Interface (STVI), the SMRT1D with an integrated on-board display, and the SMRT1B with a battery option. These units deliver strong performance in a lightweight, durable package. They support testing of overcurrent, directional, impedance, differential, frequency, and other single-phase relays.

Their flat power curves ensure maximum compliance voltage across loads, while high-resolution outputs and IEC 61850 compatibility support modern protection schemes.

Additionally, the standalone touchscreen operation simplifies manual and preset testing, meaning users can store results internally for USB transfer or detailed analysis via licence-free RTMS software.

The units operate on AC power or, in the case of the SMRT1B, optional DeWALT FlexVolt batteries. This flexibility supports efficient fieldwork. Overall, the SMRT1 series offers a reliable combination of accuracy, convenience, and portability for protection engineers and technicians.
