    Inspection and Testing questions

    I'm a bit late to this but for question 1, the Zs result is meaningless as you are testing through the output (isolated) stage of the UPS. Either put the UPS into bypass or check with the manufacturer as systems usually have inbuilt fault protection and will disconnect in around 100ms as per EN...

    Overhead tns

    Overhead TN-S. More common than you might imagine. Just tested a school on the Scottish border with one but a fallen tree had severed the earth on the overhead. DNO were out within the hour with a rather cool vehicle and 2 hours later, we had a Ze of 0.21 Ohms. By the look of the fallen tree...

    Total Harmonic Distortion Qualification.

    Liightning Protection System Testing

    Will you just 'give it a try' then? 2 million UK lightning strikes per year-this work should be carried out by an experienced engineer.

    NICEIC Certification Scheme NICEIC Partner with Rated People!

    Fair play to NICEIC for the response but I'm still amazed at how out of touch they are with us contractors that they ever thought this was a good move. Maybe some consultation on forums etc. might have been a good move before making the decision-maybe some good might come from this. Maybe ;)
