Emergency Situation
Case 2
Sometimes our emergency services can even be scheduled. One of D & D’s customers operates six days a week, twenty hours a day. Their plant was operating on a natural gas compressor but didn’t have enough back up air, and their current unit was unreliable. The customer purchased a new compressor, but the specifications for the compressor was a large amp draw. Upon inspection, we discovered they didn’t have enough power: they had a 1200 amp 3 phase 480 volt but what they needed was a 2500 amp 3 phase 480 volt.
After inspection, we also realized that the CT cabinet was rated for 2500 amp and had enough power from the transformer, but the transformer as underrated and the breaker distribution was in violation. We quickly designed a new layout for existing distribution, a new compressor, and future expansion. We also went back to the manufacturer of the original equipment and were able to pull up the original order, which provided us with a detailed list and prints of the switchgear. From there, we designed distribution to adapt to the CT cabinet and eliminated the need to install a new one, which saved our client valuable time and money. With the help of local power authorities handling the upgrade of the transformer, this project was a manageable emergency situation. We were able to schedule a Friday afternoon shutdown and expected to deliver power back by Monday morning. Our customer was thrilled when the actual turnaround time took a total of 30 hours.
