Power Quality

The following listing is intended to give an overview of the variety of projects accomplished by Quadrelec Engineering. It is by no means comprehensive.

Investigate Motor Failures

Owner:    Tinker AFB, OK
Description:    Determined cause of failure for six 100-hp blower motor failures powered through a solid-state starter. Problem resolved through improvement in motor winding construction and proper adjustment of starters.


Investigate DC Drive Problems

Owner:    Wolverine Tube Plant, Shawnee, OK
Description:    Determined cause for inadequate drive performance for a 400-hp DC drive. Problems resolved by system voltage adjustments within the plant. Implementation of recommendations in the report resulting from a companion load flow study improved machine operations plant wide. Throughput on some critical heating and extrusion processes increased 5-15% within the plant resulting in measurable overall productivity increase.
