Description
Make the BEST use of the power that is coming into your facility. Get your money’s worth!
- Increase uptime.
- Avoid line shut down due to electrical spikes, damage to equipment.
- Lengthen the life of your equipment.
- Determine why motors, wires, conductors and machinery are overheating.
-
Increase productivity.
Prevent your employees from working with computers that keep losing memory, dim computer screens and dim lighting in general.
You will learn
1 How to use a Power Quality Analyzer FLUKE® 43 to take voltage, current power, harmonic, transient and power factor measurements.
2 How to measure voltage sags and swells over time.
3 The difference between a true power, apparent power and reactive power measurement.
4 The difference between a power factor and displacement power factor measurement.
5 The effects that poor power quality will have on equipment and distribution systems.
6 The different parts (transformers, power panels, etc.) of a power distribution system and common points for taking measurements.
7 The different types (Wye, Delta, etc.) of power distribution systems.
