MCB (Miniature circuit breaker) is a re-settable device designed to protect a circuit from short circuits and overcurrents. Microsoft Excel - Advance Use With VBA; Understanding Resolution of Digital Instrument; IDMT: Discrimination by Current and Time of Operation Discrimination by Current and Time of Operation. thanks. From the Time/PSM curve of a typical relay shown below, it is seen that, if PSM is 10, the time of operation of the relay is 3 sec. Each of the two methods described so far has a fundamental disadvantage. Time-Current Curves Cables The Time-Current Curves for cables are also known as “Damage” curves. thanks. Close. Contactez-nous à : basefiable@gmail.com Abonnez-vous sur www.basefiable.com Inputs to be entered by the user to alter the result are the pick-up (It) and time multiplier (TM) setting. Dec 10, 2017. no, find it yourself . The relationship between the $$TMS$$ and the set time $$t$$ is linear $$TMS=\frac{t}{\beta}$$ where $$t$$ is expressed in seconds and $$\beta$$ depends on the curve type: The operating time is approximately inversely proportional to the fault current near pickup value and become substantially constant slightly above the pick up value of the relay. IDMT Relay Setting & Curves Calculation of Actual Plug (Relay Pick up) setting of Various IDMT Relay. Each of the two methods described so far has a fundamental disadvantage. i would like to used IDMT relay in a LT side is it possible.
