Fault Level Measurement
- If you need to verify fault levels provided by the DNO or need to confirm site specific fault levels because the DNO has not provided this data we can measure the fault levels for your site.
- A logger meter is connected to the electrical system via current and voltage transformers for a un-intrusive measurement.
Temporary Metering
- G5/4 Harmonic Surveys
- Power quality Issues
- Determining the load profile for your site or specific circuits within your site.
Firm Frequency Response (FFR) Testing
- Confirmation testing to National Grid requirements
- Results report in format specified by National Grid
