Product scope
SMRT46R is Megger’s portable multi-phase relay test system for field use. The official product page identifies electromechanical, solid-state and microprocessor-based relays as its application range.
Test workflow
Megger’s Relay Test and Management Software supports manual, semi-automatic and automated testing and includes tools for GOOSE configuration, Sampled Values analysis and fault calculation.
Engineering interpretation
Field portability is useful only when connection time, output burden, battery or mains requirements, report control and ruggedness match the maintenance workflow. For digital substations, confirm the exact hardware/software option and dataset compatibility.
Specification caution
Use the current model datasheet for exact channel ratings and do not infer SMRT46R capability from another SMRT family member.
Official sources and revision control
