Single-Phase Relay Test Systems (SMRT1, SMRT 1D & SMRT 1B) About

The SMRT1, SMRT 1D, and SMRT 1B are advanced single-phase relay test systems designed for precise secondary injection testing of protective relays in substations and industrial power systems. These compact and lightweight units provide highly accurate current and voltage outputs for testing overcurrent, earth fault, voltage, frequency, and directional relays. With modern control interfaces and compatibility with relay test software, SMRT series testers enable fast, automated, and repeatable testing. Their portable design makes them ideal for commissioning, routine maintenance, and troubleshooting of protection schemes by utilities, EPC contractors, and service engineers.

Advanced Relay Testing Made Simple

The SMRT1, SMRT 1D, and SMRT 1B relay test systems are engineered for efficient and high-precision testing of single-phase protection relays. These devices provide clear, digital phase adjustments and output status indicators, catering to modern utility and industrial needs. Compact, robust, and easy to operate, they make relay testing straightforward and reliable for both field and lab applications.

Safety and Durability as a Priority

Designed with the operator's safety in mind, these systems comply with IEC 61010-1 safety standards and feature an integrated protection system against faults. The high-grade insulation box, forced air cooling, and shock/corrosion-resistant materials provide peace of mind during intensive testing routines, making them suitable for challenging operational environments.

Seamless Operation and Data Management

Control your testing through the panel or securely via PC. The SMRT series offers convenient USB and RS232 connectivity and internal memory for storage of test results, ensuring quick data retrieval and efficient reporting. The large TFT display enables clear visualization, while intuitive menus and controls streamline testing and result management processes.

FAQ's of Single-Phase Relay Test Systems (SMRT1, SMRT 1D & SMRT 1B):

Q: How do I operate the SMRT1, SMRT 1D, or SMRT 1B relay test system?

A: You can operate these relay test systems either locally via the intuitive front panel interface or remotely through PC software using USB or RS232 connectivity. This flexibility allows you to conduct tests in various settings, including substations and laboratories.

Q: What types of relays can be tested with these systems?

A: The SMRT1, SMRT 1D, and SMRT 1B are suitable for testing, calibrating, and maintaining a wide range of single-phase protection relays used in substations, industrial plants, and laboratories, thanks to their adjustable voltage and current outputs.

Q: Where can I use these relay test systems safely?

A: These systems are designed for use in environments such as electrical substations, industrial facilities, and laboratory settings. Their safety certifications, insulation box, and robust protective features ensure safe operation under normal atmospheric pressure and temperature conditions from 0C to +50C.

Q: When should I use the internal memory for data storage?

A: Internal memory is ideal for saving test results directly during fieldwork or in the lab, allowing you to securely store, review, and transfer data to a PC for further analysis or reporting without needing external storage devices.

Q: What are the main benefits of the shock and corrosion resistant design?

A: The high impact engineering plastic and metal chassis, along with forced air cooling, confer durability against shocks and chemical exposure. This increases the lifespan of the system and ensures reliable operation even in demanding industrial conditions.

Q: How is operator safety ensured during testing?

A: Safety is a top priority, with features including compliance with IEC 61010-1 standards, a high-grade insulation box, status LEDs for fault indication, and integrated electronic and thermal protection systems to prevent accidents and equipment damage.

Q: What is the process for connecting the system for testing?

A: To begin testing, connect the system's output terminals to your relay using the supplied test leads, select the appropriate output settings on the display, and start the test either from the local panel or remotely via PC. All connections and statuses are clearly shown on the large color screen for efficient operation.
