Power Quality Analysis
To perform Power Quality Audits, McDonell Electric, Inc. uses advanced power logging instruments to analyze and record power data at a speed of over a thousand times per second. The data is used to provide a detailed, technical analysis of the internal electrical system.
Power audits allow us to identify voltage sags and swells, harmonic distortion, and other potentially harmful problems caused by, or affecting, today’s sophisticated high-speed electronic equipment.
Effects of Power Quality Issues
- Reduced Transformer Life
- Reduced Fundamental Frequency Systems
- Degraded Motor Performance
- Tripped Sensitive Loads
- Blown Fuses; Cycling UPS, Reduced UPS & Battery Life
- Telecommunications Interference
- Machines and/or Computers Resetting

Thermography/Infrared Scanning
Infrared thermography is the science of measuring and mapping surface temperatures. An infrared thermographic scanning system can measure and view temperature patterns based upon temperature differences as small as a few hundredths of a degree Celsius. Infrared electrical inspections find areas of excess heat caused by increased resistance as a result of defects in equipment connections and/or components. Increased heating is a sign of failure. Performing infrared inspections is the best way to find and prevent damage to your personnel, equipment, and facility.
Issues Detectable by an Infrared
- Loose/Deteriorated Connections
- Overloads
- Open Circuits
- Unbalanced Loads
- Inductive Heating
- Defective Equipment
- Corrosion/Chemical Reaction
Benefits of Infrared Inspection
- Reduced Down Time
- Increased Equipment Life
- Lower Repair Costs
- Prevent Catastrophic Failure
- Increased System Safety
