Power Quality Studies

• Analyze power system disturbances and interruptions that decrease productivity and reliability
• Reduce cost effect of poor power quality
• Troubleshooting power system problems caused from utility voltage sags, lightning or from medium voltage capacitors switching

Harmonic Studies

• Identify excessive harmonic distortion and loading
• Properly size capacitors in the presence of harmonic generating loads
• Evaluate and identify harmonic mitigating saving opportunities
• Solve problem due to voltage notching cause by SCR firing in DC drives
• Optimize existing electrical distribution system and ensure proper operation of sensitive equipment
• IEEE 519 compliance

Short Circuit, Coordination and Arc Flash Analysis

• Identifies overdutied equipment due to high fault currents caused by system design additions or utility network changes
• Prevents nuisance tripping of protective devices and insures coordination with downstream devices
• Checks that feeder and branch conductors are adequately protected
• Generates updated AutoCAD one line diagram model of facility
• Addresses ground fault coordination and grounding concerns
• Identifies NEC code violations
• Determines proper Personal Protective Equipment (PPE) for workers who work on energized parts per NFPA 70E or IEEE 1584
• Provides arc flash tables to determine required labels for equipment
• Determines arc flash boundaries for non-qualified personnel

Additional Studies available

• Power factor correction
• Transient motor starting
• Load flow using portable metering or simulated with software
