Frequently Asked Questions (FAQ)

Q1: What is the maximum current the D-SRC Rogowski coil can measure? A1: The D-SRC series is capable of measuring AC currents up to 100kA RMS.

Q2: Does this sensor require an external integrator? A2: While Rogowski coils typically require an electronic integrator for phase shift compensation, certain DIN-RAIL and panel meters can interface with them directly, eliminating the need for external boxes.

Q3: Can the D-SRC Rogowski coil be used in high-voltage environments? A3: Yes, it is designed with a voltage-resistant level of 36kV and complies with safety standards such as 1000V CATIII and 600V CATIV.

Q4: How does the flexible design benefit installation? A4: The flexible coil is lightweight and can be easily wrapped around large or awkwardly shaped conductors, making it ideal for places with limited access where rigid transducers won't fit.

Q5: What is the environmental protection rating of the coil? A5: The D-SRC coil features an IP65 protection rating, with some models offering up to IP67, making it suitable for demanding industrial conditions.

Q6: Does the conductor's position inside the coil affect the reading? A6: Thanks to precision winding techniques, the output is highly uniform. Typical position error is less than 0.5% near the center and less than 2% near the edges.
