How to Interpret Harmonics Data – A Case Study

Power system harmonics are commonly created by Variable Frequency Drives (VFD’s), Uninterruptible Power Supplies (UPS), computer power supplies, and LED/fluorescent lighting. These devices draw distorted current which in turn distorts to overall voltage waveform.

How to Program an SEL-351 Digital Relay


Background

The highest levels of arc flash energy are typically found at the secondaries of step-down transformers. This usually means the 480V main breakers, like the one shown above, will be over 40 cal/cm2. One method of mitigating this hazard is to install a manual reset recloser and digital relay on the primary side of the transformer.
