How do I assess the extent of the problem caused by Harmonic Distortion?
If you have equipment such as those described in FAQ5. below, then harmonics will be present in the network to some degree or other. Signs indicating a serious harmonic problem include the premature failing of electric motors and transformers, cables overheating, spurious tripping of protection devices, and loss or corruption of computer data. (See FAQ1. for the more comprehensive list). To identify the full extent of the problem would require measurements to be taken at various locations close to the harmonic generators. These measurements can be taken using equipment such as those identified in FAQ3. or by bringing in a specialist to perform a site survey. The specialist will usually prepare a report which will identify the extent of the problem and will usually offer some suggestions to recover from the problem. AIM Europe offer this site survey service, please contact us for details.
