Megger SMRT1/ SMRT 1D single phase relay test systems

Description

Introduction: Purpose Built for Next-Generation Relay Testing

The Megger SMRT1 and SMRT1D single-phase relay test systems represent a new benchmark in the field of protection relay testing and verification. As industries and utilities demand faster, more versatile, and highly accurate relay test sets, the SMRT1/SMRT1D rises to the occasion, integrating cutting-edge technology like IEC 61850 protocol testing, powerful and precise outputs, and user-friendly control. Designed for electromechanical, solid-state, and microprocessor-based relays—including directional, voltage-controlled, and impedance models—these units deliver the flexibility and reliability required in both traditional and digital substations. Their advanced touch interface, dynamic operational range, and comprehensive compatibility set them apart as a cornerstone for relay maintenance, commissioning, and system validation. These devices continue Megger’s legacy of innovation, targeting applications ranging from the simplest overcurrent relays to complex digital protection schemes.

Key System Design: Compact, Powerful, and Ergonomic Excellence

What truly distinguishes the SMRT1/SMRT1D is their blend of compact form, high power output, and durable construction. The SMRT1 features a rugged, metal enclosure with an IP20 rating and optional 19-inch rack mounting, making it ideal for field deployment or stationary lab use. The SMRT1D enhances portability with a flame-retardant ABS plastic shell yet incorporates the same advanced technology inside. Both models boast a small footprint and weigh between 4 to 5.7 kg, making them easy to transport without sacrificing performance. The built-in 10.1-inch high-resolution touch display (SMRT1D) or optional hand-held Smart Touch View Interface (SMRT1) provides effortless manual operation, precise parameter setting, and real-time result visualization. These thoughtful design features ensure the systems are not only robust, but also simple and intuitive for engineers and technicians to operate in real-world environments.

Advanced Output Capabilities: High Power and Versatility Offered

The dual-channel architecture of the SMRT1/SMRT1D delivers both high compliance voltage and high current output, optimized for a wide range of relay test scenarios. The current channel can maintain a flat power curve from 4 to 32 A (200 VA), with transient capability up to 60 A at 319 VA for short durations—ideal for instantaneous and high-burden overcurrent relay testing. The voltage channel also provides high output—up to 300 V at 150 VA, with a convertible design that allows it to act as a secondary current source (up to 5/15 A) when needed. Both current and voltage outputs enjoy sophisticated regulation; sudden changes in grid frequency or voltage do not impact output, ensuring accuracy and consistency. These capabilities translate to reliable testing for relays with demanding operating characteristics, including high-impedance, high-burden, or harmonics-based relays.

User Interface and Automation: Touch Driven and PC-Controlled

A major differentiator for the SMRT1/SMRT1D is their user interface and automation options. The Smart Touch View Interface (STVI)—standard for SMRT1D and optional for SMRT1—delivers manual, steady-state, and dynamic control via a vibrant TFT LCD touch screen. This interface enables users to select test routines, execute programmable sequences, and review metered values such as voltage, current, phase angle, or timing instantly. Manual operations no longer require a connected laptop, yet for full automation, the SMRT1/SMRT1D can be networked to a PC running Relay Test Management Software (RTMS), compatible with Windows XP through Windows 10. RTMS allows professional users to establish custom test sequences, generate and archive reports, and integrate with IEC 61850 GOOSE or Sampled Values protocol tests for digital substations. This blend of standalone and integrated operation gives users unprecedented flexibility and efficiency.

Comprehensive Applications: Designed for Relays and Beyond

The Megger SMRT1/SMRT1D is uniquely engineered for comprehensive relay testing across the entire protection scheme spectrum. These systems handle electromechanical, solid-state, and microprocessor-based relays for instantaneous and time delay overcurrent (50/51), directional overcurrent (67/67N), under/over voltage (27/59), synchronizing (25), impedance (21), frequency (81), power (32/55), voltage restraint, negative and positive sequence, and tripping (94) relays. Special functionalities include panel relay testing with high-burden options, current differential and transformer harmonic restraint relay testing via convertible channels, out-of-step (78), reclosing (79), carrier (85), loss-of-field (40), and volts/hertz (24, 24V/Hz). For advanced protection schemes, the SMRT1/1D synchronizes via Ethernet with additional SMRT units for three-phase, differential, busbar, or digital substation testing—for instance, IEC 61850 GOOSE/Sampled Values applications. Its wide-ranging frequency output (up to 1 kHz), transient playback, and Rogowski coil emulation enable it to meet evolving protection test needs for utility, industrial, and OEM environments.

Feature Highlights: Accuracy, Protection, and Communication

Innovation in the SMRT1/SMRT1D is evident in its advanced protection, accuracy, and communication features. These units offer extremely high output accuracy, with total harmonic distortion typically under 0.1% and voltage/current accuracy within ±0.05% of reading plus 0.02% of range. Real-time metering, programmable logic for binary I/O, end-to-end GPS synchronization, robust event timers, and circuit breaker simulation (for trip/reclose verification) maximize testing precision and diagnostic value. Ethernet ports permit PC control, multi-unit chaining, and IEC 61850 station bus connectivity, while optional Bluetooth enhances field usability. The systems are universally powered (90–264V AC, 50/60Hz), with built-in overcurrent, overvoltage, and thermal protections for both safety and instrument longevity. The open communication architecture means integration with third-party automation software is straightforward. Such depth of features empowers users to address classic relay challenges and new smart grid requirements alike.
