While Sinan Elias (my partner) and I were mainly working in the field as Power Testing Interns, we were assigned the task to design and build a device that would help other engineers train. The device would allow Power Testing Engineers practice 3 Phase power connections before going out to the field to liven or rewire high voltage transformers.
The device consisted of the following:
The purpose of the device was to ensure that the engineer was 100% sure of his or her 3 Phase knowledge prior to testing a transformer in the field. If a transformer were to be connected out of phase, his or her and others lives were at stake. Secondly, this transformer could be powering a hospital and if an outage were to occur, this hospital would have to run on it's back up generators, which is not ideal by any means. My partner and I wrote a procedure for how operate the device that is illustrated below. My partner and I also wrote a procedure for how to operate the device. The front of the device is illustrated below. Also illustrated below is our tri-fold poster that we presented to various executives at ComEd.
The device is powered by a Doble Power Supply and we used an Arbiter to measure RMS voltage and phase angles of each phase.
