AC Equipment Grounding: Creating a Safe Fault Current Path to Ground

Learn about the merits of the equipment grounding to protect people in faulted AC power systems. Electrical equipment casings should be at earth potential under normal conditions. When a fault occurs in an ungrounded casing, it will remain energized, creating a threat to people's safety. If you are grounded and touch that housing, a dangerous … Read more

Combining Waveforms in a Power System to Cancel Harmonic Components

Harmonics can cause transformers to fail, motors to burn out, circuit breakers to trip (nuisance tripping), and neutral conductors and other parts of a power distribution system to overheat. Severe overheating leads to electrical fires. Harmonics are caused by nonlinear loads that draw current in pulses, resulting in a distorted waveform. Harmonics is a source … Read more
