Understand Electrical Equipment Failures Efficient Plant

Mar 19, 2018Most electrical system failures are current or voltage driven events that can lead to substantial business losses in plants, including loss of production, significant equipment damage, even personnel injury or death. Two of the most common causes of electrical equipment failure involve bad connections and deteriorated insulation.

Determining Electric Motor Load and Efficiency

Determining Electric Motor Load and Efficiency

Most electric motors are designed to run at 50% to 100% of rated load. Maximum efficiency is usually near 75% of rated load. Thus, a 10 horsepower (hp) motor has an acceptable load range of 5 to 10 hp; peak efficiency is at 7.5 hp. A motor s efficiency tends to decrease dramatically below about 50% load.
