A current and load profile survey is basic survey that only monitors the current usage of an electrical installation. Monitoring the current allows you to see if you have spare capacity when looking to add additional load to an electrical installation or circuit. Flexible current transformers are used to connect around your phase conductors which means in most installations connection can be made without interfering with the power supply or arranging for a shutdown.
The survey is conducted over a 7 day / 1 week period and monitors the following electrical parameters
- A – Current
- THD I – Total Harmonic Distortion of Current
