Ohm's law (P=I2R) describes the relationship between current, electrical resistance, and the power or heat energy generated. We use high electrical resistance for positive results like heat in a toaster or light in a light bulb. However sometimes unwanted heat is generated that result in costly damage. Under-sized conductors, loose connections or excessive current flow may cause abnormally high unwanted heating that result in dangerously hot electrical circuits. Components can literally become hot enough to melt.

Infrared Solutions cameras enable us to see the heat signatures associated with high electrical resistance long before the circuit becomes hot enough to cause an outage or explosion. Be aware of two basic thermal patterns associated with electrical failure:

1) a high resistance caused by poor surface contact and 2) an over loaded circuit or multi-phase imbalance problem.

Commonly inspected components

Typical reasons for temperature hotspots or deviations

•       Unbalanced loads

•       Harmonics (3rd harmonic current in Neutral)

•       Overloaded systems/excessive current

•       Loose or corroded connections increased resistance in the circuit

         (typically one side of components heats up)

•       Underspecified components (like fuses) would heat up on both side of the fuse

•       Wiring mistakes

•       Component failure

•       Insulation failure
