TBMHA1
Mains Harmonics Current Coupler
The TBMHA1 Mains Harmonics Current Coupler is a specialized device designed to measure harmonic currents on mains (AC power) conductors for EMC and power quality analysis. It provides a non-invasive coupling method that allows instruments such as spectrum analyzers, power meters, and harmonic analyzers to monitor and quantify harmonic content on power lines without breaking the circuit. This makes the TBMHA1 valuable for conducted emission testing, power quality diagnostics, and EMC investigations in industrial and laboratory environments.
