Just interested where I could hire/buy a surge monitor/recorder, A friend of mine may be having supply voltage fluctuations (see my other post in tell us your faults.) Any help or advice, or suggestions. Thanks.

i wouldnt waste money hiring one,you can get a decent 287/289 off ebay for £200 ish,or a new one for around £400,just connect up and leave for upto a week ive got a 287, quality meter..

Thank you for your replies. I shall be checking all the connections etc. if the problem is not solved, I will be looking into purchasing a Fluke 289 which alarm man suggested. Cheers all.

Surely this unit is more suited to a TV or electronic repairman than an electrician!! most of it's features from what i can see, an average electrician just wouldn't be interested in!! Plus this is a single phase unit, or the equivalent of. I'd be wanting apart from current and voltage, KVA, KW, KWh, PF single/3 phase etc, etc from a power analyser,and these Fluke 287 and 289's are not going to give you that....

Before the leccy boards were reformed & began calling themselves DNOs I had a problem with the supply at a recording studio that I worked in.
The (then) North Easter Electricity board hooked-up a recorder/monitor to the incoming supply & let it record on a paper chart for a week or so. At the end of it all, they had a paper chart that showed all the fluctuations & the times that they occurred. Then, the fitted a box full of capacitors as a temporary measure to smooth it out until they found the cause of the problem.
In the end, it was me who found the problem - it was an electrically powered tower crane that was working on a building site a bit further along the road.

Hi... Yes I see what your saying, if the problem still exists after full examination, I will see if I can borrow a monitor from some guys who work for West Mid electric. I know a few of the engineers. If I bought a monitor, chances are I'd never use it again.

its a multimeter,just a good one,the recording of measurements is a big feature,granted its more suitable for service engineers and fault finding but still a good allround multimeter ,and would be ideal for the op,s problem

I think you'll be surprised how often you would utilise one of these analysers. Just think of the amount of times you need to ascertain maximum demand current of an installation, even more so when dealing with a 3 phase installation, apart from anything else. Connect one of these jobbies up, and you will have an accurate printable read out taken over say 24 hr period, to a number of days.
Obviously you wouldn't get all the of the parameters you would get from an all singing all dancing analyser, but then they cost upwards of 2000 quid. The unit i suggested is a basic set-up that records single/3 phase current, single phase voltage, and PF, but for a total of 300 quid, ....a real bargain!!! ...lol!!!

It Turned out not to be surge voltage problems, I inspected the installation yesterday. (Copy and pasted from "Tell us about your faults" thread) But thanks for all your suggestions.
Just to say. "I found the fault", I took note of the suggestions from this forum and yesterday I found the fault in about 20 seconds, The two incoming tails, system used to be a tt, but I had the DNO change it to TNCS with a PME. Firstly I checked all of their connections, all ok. But when I moved the Incoming live it crackled, on further Inspection I found that it was actually the cut out fuse holders male, on the suppliers side was actually loose in the carrier socket, which was actually heating up and had started to melt the tail insulation at the termination. All rectified now with a new cut out with a PME connection within the unit. Not one thats been added seperately. I can't honestly point the finger at anyone, because I had pulled the cut out fuse out at one time and put it back, so had the DNO engineer, but it's all safe now. Thanks.

Good one!
I wonder just who would / could shoulder the blame. You were naughty or the DNO negligent.
Good that you sorted it though.
