HF High Frequency Integrator

The HF is a High Frequency Rogowski coil integrator housed in a compact shield aluminium alloy enclosure. It provides precise measurement for various waveforms such as 3/5μs, 8/20μs, and 10/350μs across a frequency range of 100kHz to 1MHz. It is designed for direct connection to oscilloscopes for real-time analysis.

What does the Integrator do?

Amplify & Convert: Converts weak mV signals from Rogowski coils into standard signals readable by multimeters and scopes.
Signal Equalization: Ensures a linear response over a wide frequency range, compensating for the frequency-proportional output of the coil.
Phase Shifting: Essential for shifting the output signal by 90° to accurately reflect the measured current.

Key Features

Compatible with Y-FCT, NRC, MRC, and SRC Rogowski coils.
Available output values: 0-12V peak.
Highly flexible system for high power load analysis.
Ideal for impulsive current monitoring and DC ripple measurement.
