    Measuring Circuit (Aaron Circuit)

    Hello, We have a 3 phase power supply for our Motor and we have installed measuring equipment to check our Energy demand when the motor is running. The problem is that we only have 2 transformers in-doors so we can only clip-on the measuring equipment on 2 of the 3 phases (phase 1 and phase 3)...

    Realising an Automatic Switch for Test Circuit

    How will we waste more energy ? The motor runs around 3 hours every day and the total time of all the tests summed up is around 15 minutes spread out over that interval. I have been looking at the power and current curves at the motor circuit and they both look the same i.e have the same shape.

    Realising an Automatic Switch for Test Circuit

    The motor is connected to the main grid and it drives the generator. The time period between each instance of a test (within a test series) is pretty short... around 30seconds perhaps. It takes the motor about 7minutes to accelerate the generator from 0 to 3000 RPM. The worker has to manually...

    Realising an Automatic Switch for Test Circuit

    In our testing laboratory we perform electrical tests on Circuit Breakers and other devices. We take the required electricity from a Generator that is powered by a Motor. The test circuit includes the load (electrical device to be tested) and other needed resistances and reactances with the...
