Description

Compact, Rugged Performance for Smart Grid Testing

The Megger SMRT43 Smart Grid Relay Test System represents a leap forward in portable relay testing, engineered for field deployment with top-tier reliability. Its compact, rugged design allows it to withstand harsh environmental conditions, while its lightweight build—just 29.35 lbs (13.2 kg)—ensures easy transportation across substations and industrial sites. Encased in a fiberglass-reinforced plastic enclosure, the SMRT43 is built for engineering professionals who require robust performance and flexibility in demanding environments. This combination of portability and strength makes it an ideal solution for utility technicians and commissioning engineers. Whether positioned in cramped relay rooms or exposed to challenging outdoor terrains, the system’s resilience stands out, ensuring safety and sustained operation. This dependable build, paired with advanced testing features, underscores Megger’s reputation for delivering professional tools trusted worldwide in modern protection and control applications.

Advanced Manual and Automated Testing Interfaces Described

True to its reputation for user-centric innovation, the SMRT43 incorporates both manual and automated interfaces for diverse operational preferences. At its core is the Smart Touch View Interface (STVI), a large, full-color, high-resolution touch screen that supports intuitive manual, steady-state, and dynamic testing workflows. With menus and smart function buttons, engineers can easily select test routines, input variables, and visualize test results without any need for a computer—ideal for field work. Additionally, testing can be managed from a connected PC using the Advanced Visual Testing Software (AVTS) or the STVI software for Windows XP through Windows 10. This dual approach enables fully automated test plans, waveform and sequence editing, result storage, and detailed reporting, all with minimal chance of human error. Tests from simple overcurrent relays to complex IEC 61850 digital relays are streamlined, facilitating error-free records and rapid diagnostics.

Unique Power Output and Multipurpose Channel Configuration

A defining feature of the Megger SMRT43 is its unmatched output power capability. The system is configured with three current channels and four voltage channels, each engineered for versatility and precision. Continuous high current output delivers up to 45 amps at 300 VA per phase for brief test cycles, while sustaining 30 amps at 200 VA for extended operation. Channel configurations can be further customized by modular VIGEN voltage-current modules, scaling to meet specific three-phase or special relay requirements. For high-impedance relay testing, two channels in series can double the compliance voltage to 100 Vrms, and three currents in parallel can produce up to 135 amps at 900 VA, addressing instantaneous overcurrent scenarios. Voltage channels provide wide-ranging outputs—up to 300 V at 150 VA—with a unique flat power curve from 30 to 150 V that is essential for older electromechanical relays or panel testing. This flexible output system enables the SMRT43 to address virtually all relay configurations found in modern and legacy systems.

Powerful Applications Across Modern Power Infrastructure

Specifically designed for today’s protection needs, the SMRT43 is highly adaptable for a spectrum of critical applications in electrical power systems. It is indispensable in the testing of electromechanical, solid-state, and microprocessor-based protective relays, including overcurrent, distance, differential, voltage, frequency, synchronizing, directional power, and reclosing schemes. Utility operators rely on the SMRT43 for maintenance and commissioning of motor overload relays, transformer differential protection, generator protection relays, and ground fault systems. The system is renowned for its capability to perform dynamic, transient, and GPS satellite-synchronized end-to-end tests—a necessity for smart grid integration, grid automation, and IEC 61850 digital substations. With closed-loop simulation, professionals can troubleshoot, validate, and optimize protection settings, ensuring the reliability and selectivity of critical grid assets. The SMRT43’s performance is also crucial for routine testing in compliance with industry standards, providing peace of mind and regulatory confidence to utilities, industrial plants, generation facilities, and service companies.

Feature Highlights Elevating Testing Safety and Efficiency

Beyond raw power and flexibility, the SMRT43 integrates intelligent features that enhance usability, safety, and efficiency in the field. Constant power output technology delivers steady compliance voltage across varying loads, reducing manual adjustments and minimizing test interruptions. Immediate error indication—both visual and audible—alerts users when output amplitude or waveform deviates due to circuit issues or thermal overload, ensuring operator and asset safety. Up to ten programmable binary inputs and six programmable outputs, with Boolean logic capabilities, support advanced timing and logic operations. These can simulate circuit breaker operations, interlock sequences, and real-world protection schemes inexpensively and effectively. Comprehensive metering instantly displays output amplitudes, phase angles, frequencies, and additional real-time diagnostic data on the touch interface. All outputs are voltage- and overload-protected, supporting worry-free, long-term operation in the most challenging conditions.

Complete Communications, Modular Design and Expandability

The SMRT43 is designed to stay ahead of evolving industry standards with modular expandability and comprehensive communications. It features three Ethernet ports, supporting high-speed PC interface, chaining for multi-unit synchronous operation, and direct substation bus connections for IEC 61850 testing. An optional Bluetooth module enables wireless control, enhancing flexibility in field deployment. The system supports both floating and grounded common return configurations, catering to varied regional and safety requirements. With optional transducer testing and test lead configurations, the SMRT43 adapts to specialized applications. It is equally at home performing standalone manual tests or being integrated into an advanced multi-channel system for busbar or complex differential relay schemes. This modular approach allows organizations to tailor their purchase to current needs while ensuring long-term ROI by enabling future expansion and capability upgrades.
