Overloaded Service
Published by Dranetz Technologies, Inc., Case Study A busy trading floor was experiencing difficulties with their six air handling units, which were fed from a single 480V, 400-amp service. The units were malfunctioning, stalling and at times were unable to start, causing the temperature in the control room to rise to unacceptable levels. A Dranetz Power PlatformContinue reading “Overloaded Service”
Comparison of Compact Fluorescent to Incandescent Bulbs
Published by Dranetz Technologies, Inc., Case Study With the proliferation of Compact Florescent (CF) lighting, we thought it would be interesting to do a side by side comparison to an incandescent bulb using our new Energy Platform EP1. Not only is it a great demonstration of the capabilities of the EP1 but it’s also an opportunity toContinue reading “Comparison of Compact Fluorescent to Incandescent Bulbs”
