Description
The SDRM202 is intended to be used for both static and dynamic resistance measurements (SRM and DRM) on high-voltage circuit breakers or other low-resistive devices. Used together with TM1800 and TM1700 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.
An SDRM202 unit includes current cables and an SDRM Cable which comes in three versions, for TM1800 TM1700, and EGIL respectively. The SDRM Cable is a small box with integrated cables for connection to the SDRM202 and to TM1800, TM1700, or EGIL.
