Rogowski Coil Current Sensors

Flexible, air-core sensing for current measurement, protection and power quality.

The HVEX Rogowski coil uses a non-ferromagnetic core to provide high linearity and a wide operating range without magnetic saturation. Its compact, flexible construction fits around existing conductors, making it suitable for retrofit projects, electrical panels and installations with limited space.

Why it matters

• Non-saturating measurement for monitoring and overcurrent applications.

• Magnetic-field shielding supports stable readings near other conductors.

• Lightweight, flexible construction simplifies handling and installation.

• Suitable for utilities, industrial systems and system integrators.

Technical specifications

• Rated-current versions: 1,000 A and 5,000 A.

• Window size: 100 mm for 1,000 A; 200 mm for 5,000 A.

• Signal cable: 2 m.

• Coil cross-section: 12 mm.

• Measurement accuracy: ±0.5%.

• Phase error: ≤0.5° at 50 or 60 Hz and rated current, with a measuring instrument whose phase error is lower than the sensor's.

Standards

EMC: EN 61326-1. Electrical safety: EN 61010-1.

Applications

Current monitoring, overcurrent protection, power-quality measurement and retrofit instrumentation in electrical panels.
