Megger SMRT410/ SMRT410D multi-phase relay test

Description

Advanced Capabilities for Modern Protection Testing Needs

The Megger SMRT410 and SMRT410D multi-phase relay test system stands at the forefront of electrical testing technology, specifically engineered for comprehensive relay testing in utility, industrial, and commissioning environments. Rugged, portable, and loaded with advanced capabilities, this family of devices empowers electrical engineers and technicians to simulate all critical parameters found in operating power protection schemes. Its multi-phase current and voltage output channels accommodate every modern testing requirement: from classic electromechanical relay checks to the most intricate microprocessor-based relay calibrations. With its smart, balanced blend of high current and high compliance voltage, the SMRT410 and 410D expertly test all varieties of protective relays, including those with voltage control, restraint, and high impedance directional characteristics.

User Interface Streamlines Manual and Automated Testing

The user experience is at the heart of the SMRT410/SMRT410D product design. Operators may choose between the Smart Touch View Interface™ (STVI) handheld controller—which features a vibrant, full-color, high-resolution TFT LCD touchscreen—and the integrated onboard display available in the SMRT410D that runs Megger’s Relay Test Management Software (RTMS). Both interfaces guide the user through manual, steady-state, and dynamic test routines, offering built-in presets for a wide range of relay types. Essential measurement values such as AC/DC current and voltage, time (in both seconds and cycles), and advanced diagnostics like phase angle, frequency, ohms, watts, VA, and power factor can be displayed and recorded. This cohesive UI design makes even complex protection testing simple, accurate, and efficient in the field, reducing both learning curves and test times.

Exceptional Flexibility for Routine and Specialized Applications

One of the defining strengths of the SMRT410 and SMRT410D is their modular, scalable architecture. Each system can be custom-configured by adding “VIGEN” voltage-current modules as needed. With up to four voltage channels and six high current channels available, the SMRT410 is tailored for almost any protection relay application, from simple overcurrent schemes to sophisticated transformer differential and three-phase impedance tests. Notably, the unit’s voltage channels can be converted into current channels—enabling up to ten-phase currents for multiphase bus differential protection schemes and large relay panels. Plus, daisy-chaining multiple SMRT units allows for time-synchronized testing over even the most demanding networks, including simultaneous injection in several merging units for advanced substation and digital grid testing.

Dedicated Functions For Every Protective Device Scenario

The SMRT410/SMRT410D’s application coverage is extensive and unique. It can test electromechanical, solid state, and microprocessor-based protective relays, motor overload relays, and similar protective devices. This includes but is not limited to: transformer differential protection, three-phase impedance relays, directional power relays (both single and three-phase), negative sequence overcurrent, under/over voltage, synchronizing relays, loss of field, frequency relays, voltage and power directional, phase balance, and more. Its multi-phase capabilities mean users can test not only individual relays but large relay panels and complex schemes—such as busbar, breaker failure, and recourse to redundant systems in plants or substations. Robust output power, precise control, and purpose-built interfaces enable in-depth dynamic, transient, and steady-state relay validation, while digital communication capabilities like IEC 61850 GOOSE and 9-2 LE allow seamless integration with digital substations and smart grid architectures.

Time-Saving Features for Reliable Field Performance

Designed with practical field needs in mind, the SMRT410 and SMRT410D feature fast set-up, auto-ranging outputs, and real-time metering for immediate feedback. Automated range switching under load ensures users save testing time, as constant power outputs deliver the required current or voltage without interruption. The built-in memory on both the STVI and onboard displays allows for convenient saving of test configurations and results, which can later be exported via USB for reporting and documentation. Furthermore, the unit’s power amplifier delivers maximum compliance voltage consistently throughout the test regime, ensuring accurate relay operation and reduced repeat runs, even when burden conditions fluctuate. The rugged, lightweight enclosure means the test set is just as comfortable in a field environment as it is in a lab setting.

Key Technical Advantages that Set It Apart

The technical sophistication of the SMRT410 and SMRT410D is clearly reflected in its specifications. Each current channel provides up to 32 A at 200 VA RMS continuously and up to 60 A at 319 VA RMS for short durations, with paralleled channels delivering up to 180 A at 957 VA—sufficient for any instantaneous overcurrent test scenario. Voltage outputs range from 0 to 300 V at 150 VA, while voltage channels can double as current sources for critical relay and protection scheme testing. The accuracy of the metered quantities is world-class, with typical AC voltage amplitude accuracy of ±0.05% reading + 0.02% range and timer precision to ±0.001%. Flexible communication ports—including Ethernet, USB 2.0, and optional IEC 61850 support—allow seamless integration with third-party software or advanced digital substation environments.

Future-Ready Innovations for IEC 61850 Digital Testing

In addition to its analog testing capabilities, the SMRT410/SMRT410D is engineered for tomorrow’s digital substations. With IEC 61850 GOOSE and 9-2 LE sampled value support, users can confidently validate and commission the latest relay and protection devices in modern process bus architectures. This makes it an ideal choice for utilities and critical infrastructure operators migrating to next-generation substation automation systems. The unit can publish and subscribe to GOOSE messages, providing end-to-end digital testing and integration with substation automation equipment. Optional accessories, such as the MLLA (low-level adaptor), further expand its functionality for testing highly sensitive anti-motoring or network relays, ensuring the SMRT410 remains future-proof and adaptable to emerging needs.
