Flexible Rogowski Coil for AC Current Measurement

Jiangyin Spark manufactures flexible Rogowski coils for AC current measurement in energy metering, power monitoring, power distribution, industrial equipment and renewable energy systems.

A flexible Rogowski coil can be opened and installed around an existing conductor without disconnecting the cable. Its flexible design makes installation easier around large cables, busbars and conductors in locations where conventional current transformers may be difficult to install.

Available Output Options

Jiangyin Spark offers flexible Rogowski coil solutions with different output signals to match meters, monitoring equipment and control systems:

• Voltage Output: 100mV, 333mV, 0.5V, 1V and customized outputs

• Current Output: 1A and 5A

• DC Output: 0–5V and 4–20mA with signal conditioning

• With Integrator: for equipment requiring a standard voltage or current signal

• Without Integrator: for devices with their own integration or signal-processing circuit

Current range, coil size, lead wire length and output signal can be customized according to the customer's equipment and application.

Typical Applications

Flexible Rogowski coils are commonly used for:

• Energy meters and submeters

• Power monitoring systems

• Energy management systems

• Fault Passage Indicators (FPI)

• Power distribution equipment

• Solar and renewable energy systems

• Industrial current monitoring

• High-current measurement

How to Select a Flexible Rogowski Coil

The main factors to consider when selecting a Rogowski coil are the current range, required output, conductor size, coil diameter, frequency, accuracy and whether an integrator is required.

For equipment with its own signal-processing circuit, a Rogowski coil without an external integrator may be suitable. For meters and monitoring equipment requiring standard signals such as 333mV, 1A, 5A, 0–5V or 4–20mA, an appropriate integrator or signal-conditioning circuit can be selected.
