How we deliver your survey

Harmonic Site Surveys

To correctly ascertain your requirements a Site Survey to establishing the present levels of Harmonic Distortion needs to be carried out.

This survey works like this

Assessment of your site conditions
To conduct a Harmonic Survey it is necessary to establish the present site conditions. This has to include investigation of the supply transformers; establishment of the Point of Common Coupling (PCC); assessment of the single line distribution including pertinent ancillary equipment such as Power Factor Correction equipment on site and the method of connection of the monitoring equipment

Monitoring Equipment Connection
We go to site and connect the Monitoring Equipment. This is hooked up for one week to record site conditions.

Collection Of Equipment
Site visit to disconnect monitoring equipment after a pre-determined monitoring period, usually a week.

Harmonic Report
This detailed report will include all information required under G5/4, an associated computer program would be used to interpret current site results and predicted harmonic levels will confirm a customer solution to ensure current legislation compliance can be achieved. We conclude with our recommendations for action.
