Understanding Rogowski Coils

Rogowski coils are air-cored coils placed around conductors to measure AC current via the magnetic field induced voltage. The output is proportional to the rate of change of current, which is then integrated for accuracy.

★Wide Dynamic Range: Capable of measuring very low to very high currents.
★High Linearity: Consistent performance across the measurement spectrum.
★Non-Intrusive: Draws no power from the main circuit.
★Safe: No danger from open-circuited secondaries compared to traditional CTs.

Frequently Asked Questions

What is the main benefit of a 3-in-1 splitter?
It integrates three phases into a single output port (RJ45 or 8-pin), simplifying wiring and saving space in electrical cabinets.
What current range can this sensor handle?
The STP/MRC-24 supports a wide current range from 0.5A up to 100kA AC, depending on the specific configuration.
Does it require an external power supply?
Yes, the built-in integrator requires a DC power supply between 3.3V and 5V.
Is this sensor suitable for outdoor environments?
The current model has an IP20 rating, meaning it is designed for indoor use or should be placed within a protected enclosure.
How accurate is the measurement?
It features a typical accuracy of 0.5% at central position and 25℃, with high linearity across the range.
Can the output signal be customized?
Yes, we offer multiple selectable output voltages including 150mV, 333mV, 1V, and up to 3V AC.
