Mains Power Analysis
We carry out Mains Electrical Power Analysis surveys to all types of commercial buildings onto a specified electrical supply for a pre-arranged duration.

We currently undertake the surveys using a Dranetz 4400 Power Platform Analyser to a specified electrical supply for a pre-arranged duration of time.

      Once the Power Platform Analyser has been positioned on site, with split core current transformers and monitoring leads, various characteristics of the electrical supply being surveyed would be captured by the Analyser (See below).

Once the monitoring period is over the equipment would be removed from site and an engineering report would be prepared ready for issue to the client
