Unformatted text preview: r to solidify on a regular basis. Measure We tested our electricity savings hypothesis by measuring equipment power use data over the course of a week using the AEMC 8335 power quality analyzer. The week included three normal operating days, a holiday weekend when the machine was already scheduled to be completely shut down and the day following the shutdown. This allowed us to get an exact measurement on the amount of electricity required to remelt the solder. For example, Figure 5-4 shows the recorded power use of the equipment for the period of time when the equipment was being restarted after the holiday. Other measurements, provided by the equipment itself, included solder pot temperature during the remelting process which allowed us to measure how long it took to remelt the solder as well as normal self-diagnostic metrics on equipment functionality. Analyze Electricity cost savings would be achieved for a given period of time if less electricity was used to reheat the solder from room temperature to operating temperature than would be used to Figure 5-4: The average, minimum and maximum power usage in 1 second intervals of a wave solder machine between 12:30 AM and 6:50 AM on 7/6/2010, the period in which the solder remelted after shutdo...
