The MTCR Rogowski loops combine precision with ease of integration:
- Electrical: The MTCR-200-6000 Rogowski measuring loop measures a current range up to 6000A.
- Physical: Loop length 665 mm, opening Ø 200 mm. Mounting on busbar or cable using the supplied clamp or mounting accessories. 2 m wire outputs. IP68 protection.
- Accuracy: Class 0.5% over the entire range.
- Integration: Thanks to their opening core, installation of the current loops is possible without disconnecting power cables. Their flexibility allows easy installation in tight or hard-to-reach spaces.
- Safety: mV output, so no heating or risk of overcurrent.
- Associated products:
- MTCR-C transducers: The converters transform the mV loop signal into 0-1A or 0-5A, so the Rogowski loops can be used with a meter or a central unit with a 1A or 5A input.
- Central units and meters for Rogowski loops: Lettel offers measuring instruments to be directly associated with Rogowski current loops:
- MCX4-34V: three-phase modular meter
- MAE-96V: panel-mounted measuring central units.
The Rogowski measuring cores can be connected:
- Directly to modular electric meters MCX4-34V or to panel-mounted measuring central units MAE-96V
- To any meter or central unit with a 1A input using the converter MTCR-C-x-1
- To any meter or central unit with a 5A input using the converter MTCR-C-x-5
- Mounting accessories ensure optimal accuracy class:
- Mounting on cable: MTCR-S3
- On busbar or cable: MTCR-SV
- With voltage pickup cord: MTCR-CU
- Accessories:
- MTCR-S3: Triaxial mounting support for fixing the Rogowski loop on a round conductor (cable).
- MTCR-CU: Mounting support for fixing the Rogowski loop on a busbar.
- MTCR-SV: Voltage pickup cord to be used with the MTCR-CU mounting support.
