Cheers for all your help don t know if it will get me anywhere. See the problem is I'm the company's only spark and no one else understands. We basically have periodic test every 4 years and what ever gets marked down I have to sort (with in reason) this compressor has been In about 12 years...
Hi people I'm back so my company have spoke to the test and inspect company and the are still saying max zs allowed is 0.18ohms because the table in the regs state this now. Now I know you can calculate this (just struggling doing it at the moment any help appreciated) Iv looked at Schneider...
Cheers for all your help that's what I thought but before going back to them and saying this is wrong the circuit is fine and complies. I didn't wanna make my self look like an idiot and I had missed something. I just wondered if something changed in 3rd amendments and I could find it. Thanks again
Sorry type error 0.21 ohms. So I'm right in thinking the circuit is fine and should be calculated at 5 sec disconnection not the 0.4sec they have reported and it is actually there report that is incorrect. On the report it say 0.4 disconnection and a max zs of 0.18ohms a give the report a c2
Hi all just a little bit of advice at the company i work has just had a condition report done and they have marked down excessive zs for a 63a type d breaker but they have put it at 0.4 disconnection time it is a permanent fixed compressor I thought this would have been 5 sec it also has a b.s...
Thats what im thinking as i have a mitsubishi plc but software for it is as expensive as a starter kit. Do you know if mitsubishi alpha 2 starter kit is any good as i can get a complete kit for around 200
We use Mitsubishi and Siemens s7. as I said I have a spare Mitsubishi fx series just need a cable and software really maybe that would be the best solution do you think the Mitsubishi is easy enough to learn with not naving much knowledge I can read electric drawing and I have knowledge on logic...
I am from Wolverhampton and cant seem to find any local I know Siemens do 1 at Manchester but its £1000s to do and to far to go after I finish work. and I only want to have a play around first see if its something I want to go into before paying £1000s on and spending hours on which I know you...
hi im very interested in plcs. I would like to learn them but there is not much out there as far as collage courses. I work in maintenance and we have plcs at work usual have a guy in who sorts them out if ever needed he said to try get a starter kit have a play around with them a try to self...
Yer theres no neutral at all. Iv not got the inverter yet just looking at the job and seeing what options i have got but think iv answered my own question. cheers
I get all that bit as iv done it before with 415v brake and brake rectifier but this is old and uses 230v which is tapped from the star side of the motor to act as the neutral. Like i said probably with running it separately is there is no neutral which is why said is the only way to run a...
Hi iv been asked to fit a 3 phase inverter to a motor with a 230v brake which is using the star side of the motor for the neutral. Now iv fitted inverters before with a brake i know they make them chatter so you put a contacter in to switch the brake separately. My problem is the neutral there...
