Megger SDRM202 Static / Dynamic Resistance Measurement Unit - TM1800/1700 or EGIL
Description
The Megger SDRM202 is a static and dynamic resistance measurement accessory for the TM1800, TM1700, and EGIL. For use with EGIL, the EGIL must be equipped with the SDRM option and CABA Win version R03A or higher.
Using the SDRM202 together with the TM1800, TM1700, or EGIL, enables you to measure the current and the voltage drop across the circuit breaker contacts. The measuring unit can thus calculate the resistance as a function of time.
A system consists of an SDRM202 unit with current cables and an SDRM Cable which comes in three versions for TM1800/1700, and EGIL respectively. The SDRM Cable is a small box with integrated cables for connection to the SDRM202 and to the TM1800, or EGIL.
A timing cable is included with the TM1800 timing module. Transducer cable is selected together with the type of transducer used.
