  • Abstract
    S/DRM testing methods usually use long, heavy cables to connect high current source from ground to the circuit breaker. Alternative is to move current source close to the circuit breaker by using heavy batteries, transformers, dc/dc etc. In this proposed method batteries are replaced with ultra capacitors and constant current charger, resulting in a few hundred grams of powerful current source, capable to generate few hundred amperes into the breaker contacts, or any other power contacts. Measuring voltage drop across the circuit breaker and the current through it continuously monitors discharging of ultra capacitors, giving a high accurate resistance value of the measured object.
