Problems we solve

Identifying and finding solutions to power systems problems are one of our specialties. Here are a few examples.

Power outage root cause failure investigation with recommendations, including analysis of sequence of events, event recorders, historians, and other data.

Identifying causes for blackouts, then resolving the root cause for the outages, which are frequently caused by protection relay mis-operation.

Finding solutions to voltage quality issues causing equipment or production losses such as VFDs tripping, motors stalling, capacitors failing, or other issues.

Helping clients to meet utility requirements for harmonics, such as IEEE 519.

Performing power system analysis for connecting new equipment (such as large motors, transformers, or generators) to ensure no issues are discovered during commissioning and start-up.

Performing arc flash hazard assessments to meet NFPA, IEEE, and CSA requirements.
