Generator connection

[Dylboy]

@Dylboy. Yes, not vov for sure. I've checked if vov then the voltage is split 50/50 whether there is a load or not.

Also, I cannot see 3 thick leads coming from the stator. Only 2, live and neutral. On vov wound, there are 3 thick leads coming from the stator with one of them (centre tap ) connected to earth.

Gonna do more tests on Monday.

Gonna connect it to installation and see if earth leakage works as it should.

Peace out .. Derek

Ah brilliant! well hope will all be alright once installed! Keep us posted if you can please on the outcome.

Will try find out more why you got those reading on no load as well

Tested a generator this morning. The specific model ...... Ryobi rg 6900K.

Results as follows:

No load ..... L - N 235V ; L - E 160V ; E-N 75V

With load .... L - N 235V ; L - E 235V ; E-N 0V

Is there anyone who can explain this. I'm wracking what's left of my brain cells but cannot understand it.

Peace out .. Derek

A multi meter has a High Impedance and will tend to pick up " stray " voltages - If you used a meter with low impedance ( duspol tester) you would find the reading would give the same as on load readings

Thank you GCE.

I'm going to dig out my Manox from appy days and check it again on Monday.

Enjoy the rest of the weekend.

Peace out .. Derek.

Hmmm. Now you've inspired me to dig out my Avo Meter. I actually found a battery for it, must buy that.

Derlyn ... please plug in your ELCB socket and polarity tester (the one with 3 led lights) let us know what see.

An important note.

@Ian
Gonna do some more testing tomorrow.
That was on my list of things to do.
Far from finished playing around with gennys. Too much that I still do not understand.

Vov is easy.

Disconnect the centre tap and connect the neutral to earth. Sorted.

These new gennys are not vov wound. They only have 2 thick wires from stator, namely live and neutral. There are about 6 or 7 thinner wires also coming out from stator. At this stage I don't know exactly where they connected or if they are connected to the stator, but I'm gonna carry on until I find out. Must have something to do with regulating the speed and voltage output.

Will keep you posted.

I just saw the email with the original post. Check to see if the generator N and E are bridged.

Ok, some feedback.

Generator no load, only 2 lights on plug tester.

Opened generator and found the earth is floating. Hit in earth spike and earthed genny .... problem solved. 3 lights and earth leakage trips.

Disconnected earth spike, back to 2 lights on plug tester.

Opened genny and bridged neutral and earth. Connected to installation and tested. 3 lights, earth leakage tripped with tester as normal.

It seems safe to say that if the genny is NOT VOV then bridging the neutral and earth on genny is the answer, but first make sure that its not vov wound.

Interesting little exersize.

Will post some photos this evening.

Peace out .. Derek
