Why PQube 3?

  • PQube 3’s equipped with cellular modems.
  • Automatic reporting
  • Data ready to view (gif files)

– Even non-technical individuals can understand the graphics.

  • No site visit required to gather recorded data
  • Daily / weekly / monthly trend information easily understood
  • Event detail as it occurs
  • PQube 3 can be reconfigured remotely

  • L-L voltage no

amplitude change

  • L-N voltage variations
  • N-E voltage variations

follow L-N variations

  • N-E voltage

adds/subtracts from L-N voltage amplitude

  • No corresponding

current changes

Lonie’s Laws of PQ Problem Solving

  • (1 of 2)

1. Do the simple things first. 2. There is always more than one problem. There are always more than one or two problems, keep looking and you will find them. 3. The problem investigation is like peeling the layers of an

  • nion. When you peel away the last layer the onion is

gone…and so is the problem. 4. Fix the problems as you find them…if you can. 5. The customer (aka client) NEVER tells you the whole

  • story. Every time you talk with them you learn another nugget
  • f knowledge.

6. Never believe someone else's measurements or test

  • results. Worst case, you verify the readings and test results

are correct.

Lonie’s Laws of PQ Problem Solving

  • (2 of 2)

7. Be nice to everyone, you never know who will provide you with an important clue. 8. If it is happening in the electrical environment you can figure

  • ut a way to measure it.

9. Substitute technology (multiple monitors) for time…it speeds up the investigative process and provides more and better quality data for analysis. Labor (time) is the most expensive cost component of an investigation, equipment (technology) is relatively inexpensive. Use equipment with remote communications capabilities to save labor.

  • 10. You are NOT allowed to repeal any of the basic laws of

physics.

  • 11. Ohm’s Law and Kirchhoff’s Law solve most problems...use

them wisely.
