Hi, I have a customer who has airband going to one house currently, and wants to split it to another house at the same site (its a farm with 2 cottages) Is there any reason why I cant do what is shown in the drawing attached? Basically the airband dish and power supply is currently at the barn...

Thank you for all the replys. I have now ordered some parts, funnily enough pretty much as Harry Bloomfield suggested. Was having a blonde moment, and couldnt work it out before!!

Thanks, what is the FSD? The ammeter I linked to has no mention of FSD? Are you able to pick one on RS which would work? Basically the application is for monitoring the current draw on a 3 phase motor, (only one phase needs to be monitored), hence why i want to use a CT rather than a direct...

I want to set up a ammeter to monitor current on a circuit, using a CT. Current should be around 25A (240V). I can't get my head around which ammeter and CT should work. Looking at a couple on RS, can someone guide me as to how to choose two which are compatable? Thanks...

Sorry for the delay in updating you all. So I went there on Friday morning to have a look. It turns out that they have increased the amount of product being put onto the belt. So instead of say 200kg being on it at any one time, there is probably double that now. If only all this information was...

True about the thermal overload, I left it in as the manual says too. It is the Invertek E3 invertor. You can set the type of load, there is fan and pump, or standard. As this is a conveyor, I have left it on standard. I had them monitor the current drawn this evening, (on the display) and it...

On supply to invertor .

I have just fitted a 4kW invertor to a 3Kw three phase motor which runs a conveyer. All settings are as it always use to be when it was DOL with a running speed at 50hZ. All was fine for half a day, and now the invertor is tripping out on overload about once an hour. The conveyer only runs for...

Why would an electronic ballast go faulty when removing a tube?

UPDATE - today one of the fittings had both old tubes lit. I removed one tube, and as I did I heard a pop, and the fitting died. It was live at the time of removing. I have never had a ballast die on removal of a tube, let alone 6 fittings in total (differnet ages too) all do this. Seems very...

There is 6. Makes it difficult to check the motor windings properly as the connections are within the motor. But yes, I could check there isn't a short between the two sets of three.

This is something I will look into for sure. Thanks.

I believe it trips on both speeds. Its a motor which lifts the blade up and down, I believe on a worm screw type of set up. There is no way to test the windings, as the actual winding star point is inside the motor.

Customer has a saw which has a small motor which from looks of it has two sets of windings/poles for two speeds. It can be operated manually or as part of a program using the PLC. However it is operated it is the same thermal overload and contactors which operate. It is tripping the thermal...

Only some tubes were still working - I was going to relamp the whole building at the same time.

Cheers Rocky. The fittings were live when changing the tubes, but I also powered off and tried re-starting to no avail. The fittings don't look that old, possibly 5 years or so, but they are on all day 6 days a week, so could just be the ballast are at the end of their life. Just frustrating...

I fitted some 6ft Philips TL-D Super 80 tubes to some fittings, which had Osram Quiktronic QT-Fit8 electronic ballasts. On fitting the tube the ballast popped and that was the end of it. Tried putting the old tubes back in (which were working before removing) and they were also dead. I tried...

All good ideas Ken. Thank you
