The SDRM201 is intended to use for both static and dynamic resistance measurements (SRM and DRM) on high voltage circuit breakers or other low resistive devices. Used together with EGIL the current and also the voltage-drop across the circuit breaker contacts are measured. The measuring unit can thus calculate the resistance as a function of time.

A system consists of an SDRM201 unit with current cables and an SDRM Cable The SDRM Cable is a small box with integrated cables for connection to the SDRM201 and to EGIL.

Features:

Enables resistance measurement on circuit breakers
Small and light weight
A number of operations can be run with short waiting intervals
