Product Description

The Y-FCT is an Ø8 flexible current transducer based on the Rogowski principle, specifically designed for measurement in combination with portable devices. These coils are available in various sizes and can be tailored to specific design requirements, making them ideal for applications where traditional transducers are unsuitable due to size or weight constraints.

✔

High Linearity: Accurate measurement from 1A to 100kA.

✔

Flexible Design: Ideal for awkward shaped conductors or limited access areas.

✔

Safe Operation: No danger from open-circuited secondaries or large overloads.

✔

Non-Intrusive: Draws no power from the main circuit.

Application & Packaging

Frequently Asked Questions

Q: What are the main benefits of using a Rogowski coil over a traditional CT?

A: Rogowski coils are flexible, lightweight, and non-intrusive. They do not have a magnetic core, which means they don't saturate and can measure very high currents (up to 100kA) with high linearity.

Q: Can the Y-FCT sensor measure DC current?

A: No, Rogowski coils only measure AC current. However, they can measure the AC component accurately even when a large DC component is present.

Q: Is this current sensor waterproof?

A: Yes, the Y-FCT features an IP67 rating (with some versions up to IP68), making it suitable for harsh environments and outdoor applications.

Q: Does it require an external integrator?

A: The coil outputs a voltage proportional to the rate of change of current (di/dt). It needs to be connected to an electronic integrator or a compatible meter that can handle the phase shift and signal processing.

Q: What is the standard lead cable length?

A: The standard lead cable length is 2 meters, but customization options for different lengths and coil sizes are available.

Q: What is the operating temperature range?

A: The device operates reliably between -30ºC and 80ºC, with a storage temperature range of -40ºC to 90ºC.
