Abstract:
Testing of MCBs involve sending a preset current
through the MCB under test until it trips or if not for a predefined
period of time. The operational state of the MCB should
be recorded for variable currents. Automation of the testing
process for household MCBs is presented in this paper.
This paper includes design of the testing process and
simulation of the controllable current source. Maximum current
which can be injected by the current source is 390 A for a short
time duration.
