In most cases the Profile Portable Energy Recorder will be used to monitor energy use on three phase or single phase, low voltage circuits. However, high voltage energy monitoring surveys are also possible with the Profile using the Two Wattmeter Method.
The guide below details how this can be done. Please note that this method is only possible with the Profile V monitor. The Profile IV can not be used to monitor high voltage circuits without manual alteration of survey data.
If you have a Profile IV Energy recorder and wish to perform high voltage energy monitoring surveys please contact NewFound Energy about upgrading your Profile.
What follows is intended as a brief guide only. Please see the Profile Installation Guide and the full Profile User Guide for more details as well as general installation and safety guidance.
It is assumed that the user is familiar with the basic operation of the Profile and that the Profile is set to automatic Current & Voltage ranging as will commonly be the case.
Throughout this guide where reference is made to cable phase colours, the new cable colouring is stated first with the old colour after it in italics.
Warning: Installing a Profile Portable Energy Recorder system can involve working near to exposed electricity carrying cables or bus bars and should therefore only be performed by a suitable person with the relevant electrical safety qualifications.
