What the Advantages of Power Quality Monitoring Mean for a Plant

What the Advantages of Power Quality Monitoring Mean for a Plant

Advantages of power quality monitoring: capture sags and harmonics, choose a campaign or continuous recorder, then buy the right plant correction.

How to Calculate Power Factor from kW, kVA, and Meter Readings

How to Calculate Power Factor from kW, kVA, and Meter Readings

Learn how to calculate power factor as kW divided by kVA, with single-phase and three-phase steps, worked examples, and caveats when cos theta is not enough.

What a Discharge Resistor for Capacitor Bank Does After Disconnect

What a Discharge Resistor for Capacitor Bank Does After Disconnect

A discharge resistor for capacitor bank bleeds residual voltage after disconnection; keep the two printed residual-voltage times separate on a plant cabinet.

What an Internally Fused Capacitor Bank Isolates Inside the Unit

What an Internally Fused Capacitor Bank Isolates Inside the Unit

An internally fused capacitor bank places a fuse with each element inside the sealed unit, isolating a failed element so remaining parts can stay in service.

How Power Factor and Power Factor Correction Work on Plant Buses

How Power Factor and Power Factor Correction Work on Plant Buses

Power factor and power factor correction on LV plant buses: what lagging PF means, how capacitor banks correct it, and when automatic stages fit.

What Capacitor Bank Unbalance Protection Watches on a Plant Bank

What Capacitor Bank Unbalance Protection Watches on a Plant Bank

Capacitor bank unbalance protection watches the unbalance after an element or unit fails, then alarms or trips before remaining units see a higher voltage.
