The analysis of "Power Quality" evaluates the electrical energy
going to equipment in the form that will allow the system to operate properly,
efficiently and minimize long term risk to that equipment. The parameters
of Power Quality include voltage, frequency and waveshape most generally
in the form of a sine wave. Most computer equipment will operate within
a certain tolerance curves. This study will verify if specific equipment
tolerances, as specified by the manufacturer, and verify if the power
quality is adequate for the equipment to run properly.

Troubleshooting power quality problems can be accomplished in many ways.
One of the simplest methods is to start off by determining into which
of four major categories a potential problem falls. These areas are 1)
A grounding problem, 2) A transient problem, 3) A harmonics problem or
4) No power quality problem at all. Each of these studies, are listed
within.
We can diagnose any of these problems to help you control and monitor
these events. We can also design and install a permanent system that will
send all of the data to a central computer within the facility. We can
then provide consultation services when future problems arise.
SUGGESTED SERVICES FOR A POWER QUALITY AUDIT /
STUDY
- Temporary metering and monitoring of the electrical system to analyze
power system disturbances and interruptions that will decrease productivity,
reliability and efficiency. We can perform the tests for each floor
in a building to detect harmonic issues, power quality and determine
the load per floor. These tests can be done over time. It can be performed
in a few hours or up to a few weeks, depending on the level of data
detail required by the owner. Approximate meter cost is $2,500 per point
in the system to be metered. We will help to determine what is required
to get the most data.
- Evaluation to identify and diagnose electrical system and equipment
risks and procedures before they become costly problems.
POWER QUALITY MONITORING & ON SITE MEASUREMENTS
- Power quality studies, harmonic analysis and harmonic filter design.
- Power quality metering and monitoring and on site measurements.
- Temporary and permanent power quality monitoring to facilitate problem
solutions.
- Power monitors capture voltage and current harmonic distortion and
disturbances that can adversely impact electronic equipment.
- Documenting and trending system performance to increase system reliability.
