Thanks for your replies

I know been doing this - looking to automate and provide info out... running over 150 ips at present and looking for realtime analysis

Hi I hope that you can indulge me ! I am currently looking at a system and would like some advice - we have several remote items of equipment that we monitor through the net and as such I am looking at a way of monitoring the network that monitors our equipment. What I seek to do is have a...

If I told you then I would need to kill you......

Cheers for this information - The earth connection between the two points would be pretty much solid and not through electrode - bit unclear from the drawing. The metal of the busbar would be one path and Im sure that there would be other paths availiable through the installation between the...

First lesson - its a game second lesson - stop trying to win just play third lesson - rules are negotiable forth lesson - you can stop and go home when you want fifth lesson - the reward can be huge - but it comes at a price sixth lesson - some people hate playing games when they start to...

Now you know why its called a fluke - if you get it home and all the data is there then it will be a fluke - sorry to hear of your trials, usually find fluke to be pretty good equipment. With the price of laptops and tablets etc would it be a better idea to take and download any data off of the...

Find attached a quick drawing hope it makes it clearer... The shorted turn effectively shoring out the other CT's is what I had thought and only wanted to confirm this. Im also dubious about this in operation for any length of time having an effect on the CT's - maybe upset the balance...

Putting up a sketch now thats getting technical lol.... Transformer star connected three phase out along with neutral running through busbar to the main feeder board. The main feeder board having the incommer ACB. 4 CTs are located on the L1-L3 and N bars before the ACB. 4 CT's are located on...

Hi It is a 400 / 230 system - standard uk fare. Building is reasonably new and looks like the paneboard installers didnt talk to the transformer installers and the checker must have had a day off the day they connected it all up.... Didnt think on the neutral / earth making it trip at a lower...

This is something that Ive witnessed a long time ago and it is a nightmare fault as the generator current falls away very quickly. The whole set up of protection depends on a sizable current being provided to a fault to enable the protection to operate as intended. Having a utility supply...

Recently discovered an error that has been present for over 5 or 6 years now with a set up. We have identified that we have multiple neutral earth points inadvertently installed on a power distribution system. My question on this involves the CT set up - if we have been running with the neutral...

This sort of set up opens up a few things that you need to take into consideration. Maximum load step ! Working out in bosnia we had a kitchen feed breaker trip on the run up to feeding time. kitchen worker saw the switch panel open and saw the tripped breaker and put it back on. But by this...

http://www.ascom.co.uk/uk-en Try this - we use them to provide telephone contact and in addittion the system relays all alarms out to the pager so that we can see instantly what alarm has been recieved by the building management system (trend) A good way of keeping ontop of all that is going on...

Hey Shhhuuuuush about the tin wiskers - work in a data centre and mention tin wiskers and you can see all the facilities guys go a whiter shade of pale. Its still an issue and one that is causing headaches - a manufacturer of computer racks used tin plated metal work within the racking assembly...

Running a UPS in parallel with the supply is not a good move as this can cause issues with the UPS when there is a power failure the back feed can confuse the UPS as it sees a healthy supply which is being created from the UPS output. This can lead to a destabilised output that would wreck havoc...

The salt water rehostat is pretty funky - If you are playing with DC then you will get some hydrogen from one of the electrodes, and then if you were to create a spark, yep one almighty pop ! and a poop in your trousers.....

Its not that expensive to add in some undevoltage protection - voltage relay and some form of timer relay - Im sure that this could be added reasonably easily and give you the peace of mind that you are looking for. Also this has to be weighed against the effects of what a bolted short would...

Its not safe to have a generator that doesnt trip- but this type of set up you should have protection set into the system to pick up any faults. As said a bolted fault causes the voltage to decay a relay can pick this sort of change up and trip the incoming breaker to the motor. Looking at this...

Yep well put bad mamma jamma
