Technical Features and Field Applications of the Megger SMRT410
Understanding the technical specifications of the Megger SMRT410 is essential for evaluating its suitability for your testing requirements. The device features a high-definition TFT LCD touchscreen that displays critical meter values, including AC and DC amperes, AC and DC volts, and time in seconds or cycles. Depending on the test type, it can also show phase angle, frequency, ohms, watts, VA, and power factor. Below are the detailed specifications and their practical applications in the field.
- Input Power Requirements: The SMRT410 operates on 90 to 260 Volts (±10%) AC, single-phase, 50/60 Hz, with a power consumption of 1800 VA. This wide input voltage range makes the device highly adaptable to various power sources found in industrial sites globally.
- Phase Angle Ranges: The unit supports phase angle ranges from 0.00 to 359.99 degrees with counter-clockwise or clockwise rotation options. It also offers a range of 0.00 to ±180.00 degrees. With an accuracy of ±0.02° typical and ±0.25° max at 50/60 Hz, this precision is vital for testing directional relays and ensuring accurate phase synchronization.
- Frequency Output and Ranges: The output modules provide variable frequency output ranging from DC 0.001 to 1000.000 Hz. The resolution is 0.001 Hz, allowing for fine-tuned testing of frequency-sensitive relays.
- Transient Playback Capabilities: The output amplifiers can generate transient signals with a range of DC to 10 kHz for transient playback using COMTRADE files. This feature is crucial for simulating real-world fault conditions and validating the response of digital protective relays.
- Frequency Accuracy: The device boasts a frequency accuracy of 2.5 ppm typical and 25 ppm max from 0° to 50° C at 50/60 Hz. This high level of accuracy ensures reliable testing of under-frequency and over-frequency relays.
- AC Voltage Amplitude: The SMRT410 provides AC voltage outputs in ranges of 30, 150, and 300VAC. The accuracy is ±0.05% reading + 0.02% range typical, and ±0.15% reading + 0.05% range max, with a resolution of 0.01. Measurements are displayed as AC RMS, essential for testing voltage supervision relays.
- AC Current Amplitude: For current testing, the unit offers ranges of 32A and 60A with an accuracy of ±0.05% reading + 0.02% range typical. The resolution is 0.001 or 0.01, depending on the setting, providing the precision needed for overcurrent relay testing.
