Power Quality Industrial Electronics (VFD’s and PLC’s)
|
Powertronic, Inc. has numerous power analyzers readily available for scheduled or emergency service calls. We don't rent our equipment, we own all of our equipment. This ensures that we are experienced with the equipment we use and it is well maintained and routinely serviced and calibrated.
Troubleshooting, Analysis and Surveys The term "Power Quality" has really been bandied about over the last few years, and with good reason. The tremendous expansion of the computer industry and the common use of variable speed drives have contributed to power quality problems. The introduction of IEEE 519 is the first step in establishing acceptable standards of power quality. What is poor power quality? Harmonic Distortion or Electrical Noise caused by variable speed drives or electronic devices. Sags (undervoltage) and Swells (overvoltage) in excess of 10% of nominal system voltage. Transients, voltage spikes of high magnitude and short duration. These may be several hundred or thousands of volts above nominal system voltage. Outages (complete loss of power) in excess of several seconds If these symptoms are present, the possibility for problems exists. Computer lockups, burned up motors or circuit breakers and over heated neutral conductors are just a few of the problems than can develop. Powertronic, Inc. can provide assistance with these problems in two ways: one reactive and one proactive.
Troubleshooting Power Quality is something that can be measured and monitored. A survey may help identify impending problems but if you are already experiencing equipment trouble, the power monitoring equipment can be used as a troubleshooting tool. If your electrical system is exhibiting a problem and causing downtime or losses we will come to your facility and ascertain the impact on your facility or process. An assessment will be done with some data gathering and if necessary a Power Analyzer, such as the Dranetz PX5, Powerguide 4400 or 4300 Power Platform, can be temporarily installed. Monitoring may be done over days or weeks depending on the problem. Information is recorded and a report generated with two software programs including data, graphs and analysis. A complete report is prepared and in conjunction with your staff a list of solutions is developed and implemented.
The survey is taken to establish a baseline of the power quality or usage of your facility. A Power Analyzer or Power Monitor is installed for a brief period, a week or two, and a report generated detailing electrical usage and potential problem areas. This report will include typical load throughout the monitoring period as well as specific harmonic data. As your facility expands or changes, subsequent surveys can be completed and compared with the baseline information. This type of baseline information will be very important as the problems with the electrical system develop or you contemplate expansion of your facility. You only
need to provide clear access to the equipment to be monitored and the
ability to secure the monitoring equipment.
