Hi Steve,
I did something quite similar I am a qualified electrician and then done my HNC at night school. I now work for my local DNO in the northwest and am authorised to work on equipment upto 132kV under supervision (only been here 2 years). Companies like Western power...
I have worked with a few US sparks and most of them said they never test an installation turn it on and hope for the best. Most had never heard of a zs before either! get ready to start sharing neutrals and earths on final circuits. One lad who I used to work with states that in las vegas (maybe...
I went down the HNC route and got a trainee engineering role in the HV industry. Alot of large engineering firms railways/utilities etc will look at sparks with HNC to train up. Good if you want off the tool but not ideal for evryone as I miss being busy haha
I disagree to a certain extent. I know a few lads who earn good money off my builder and provide them with alot of regular jobs. I had a page when I needed extra work and you do pay large amounts for REWIRES and I have had the same situation where the installtion was fine and the client was just...
Where I am working at the minute (DNO)they use massive well built unbrellas, best thing I have ever seen to work dry. Slam in the ground or strap to something great bit of kit. Shame I didnt have one a few years ago changing outside isolators up and down the country some days looking like I just...
Hey guys I've have to isolate a panel fed from a system4 old submain panel but cannot seem to get the isolator handle down to a fixed off position. It is on a spring which as soon as I realise it goes back to the on posistion. I have used all my strength but it seems am missing a trick...
Hi guys currently doing a hnc and I am stuck on a question regarding the lumen method of lighting design. Ill post the question underneath-
A workshop is 40mx50m to be illuminated with 1000w high pressure mercury vapour lumnaires providing an illuminance at working level of 283 lux. The lamps...
I have fitted a few shower pumps, when the shower is turned on the a signal is sent from the water sensor which in turn asks its control unit to start the pumping. Now this was a black sensor on the cold feed for the shower with 2 wires coming of it now maybe that has become faulty and needs...
This sounds like they must have new rules or just being stubborn. I live in the north west and about two years ago I had the same problem, rewired a house but was getting readings indicating a very poor earth, got onto the local DNO saying the house didnt have a proper earth and they needed them...
engineer54 I have always thought a tncs system worked your way but as i have never worked beyond an installation ie in the network so have not had any experience of working with to many differnt systems. When I started my new job working along side generators two sparks there explained to me...
Enginner54 I did not say that a earth was not required at the neutral star point of the genny. I know it is earthed to the can of the genny and then on to a ground rod. As my statment read i have just started working with generators and have been informed that on a tncs system a ground rod was...
In regards to an earth rod, ive just started working with generators especially tncs systems. I have found that an earth rod is used mainly as a lighting protector only and that any faults with the systems go to the star point on the transformer via the neutral. Meaning a rod is not always...
yes but also i hear reverse trigonometry is in here as well. Theres that many new math equations to learn its time consuming but in my collage the tutors are very helpful so its not as hard as it should be. Theres a engineering maths book which makes its easier to understand ill try and find the...
