HARMONIC SURVEYS

The effect of electronic equipment installed on a Power Supply Network is to cause a deterioration in power quality. With the increase of electronic loads on the network power quality problems will continue to rise. Our experienced engineers can carry out pre and post harmonic surveys to G5/4-1. These surveys are particularly important when you install or add additional variable speed drives onto a power supply network.
A harmonic survey is carried out to establish the existing levels of Harmonic Distortion on the network and would include:
ASSESSMENT OF EXISTING SITE CONDITIONS
CONNECTION OF MONITORING EQUIPMENT
Site visit to connect the monitoring equipment
DISCONNECTION OF EQUIPMENT
Site visit to disconnect the monitoring equipment after a pre-determined monitoring period
HARMONIC REPORT
A report on the findings and recommendations on equipment selection, such as Siemens Power Quality Filters.
