Current Measurements

EHT integrators have been used for high current measurements in applications were current transformers saturate. The figures shows a 2.5 kA current pulse for 10 ms. The current transformer (green) saturates after a few milliseconds. The EHT integrator, paired with a Rogowski coil, was able to measure the whole pulse. The kink in the current…

Magnetic Field Measurements

EHT integrators measure both extremely small fields and extremely large fields with high precision. For example, if connected to a loop with a 0.1 m2¬†area (100 turns 3 cm in diameter) wound on ferrite with a relative permeability of 1000, the integrator would produce a 1 mV output when measuring a 100 pT field. When…
