Hi. It is brushless.The battery voltage is 6V.I measured the voltage across the exiter coil(4,1V) and then at the terminals where the exiter voltage goes into the AVR(1,4V)

Hi ,I need to check on that.thanks

I need help please.I am stuck with a 3,3MW Hydro generator that wont exite when exitation is selected after the machine reached operating speed,I tested the rotating diodes,exiter and auxilary exiter windings .Even external exitation with a 6v battery didnt help.When I test the exitation...

We have to re-route a 33KV XLPE cable.Can anybody tell me what the required depth must be for the cable to cross under a road.

Hi. The insurance company want us to built Blast/Firewalls between our gensets and transformers.Can anybody give me some advice regarding regulations or standards.

Hi Laundry. Thanks . None taken.When I megger between phases ,should it also be on 10000V scale

I need to megger a 6,6KV motor.I will be using a 5000/10000 Volt megger.What scale shoud I use and what must be the minimum ohm value be.Thanks

Thanks I will.

Hi. Hope somebody can help me.We use a Sulzer Sicos 1200 control system on our Hydro gensets.I need spares but Sulzer Brothers in Winterthur Switserland has closed or moved.I need contact numbers please.

I am trying to log data voltage,frequency etc.I measure 110v from the VT.In the meter's menu you can select several ratios and the one I need is not there,they have a 100/1 ,I need 110/1 .It is on a 6.6KV system.Can anybody perhaps help?.

We have a hydro generation station comprising of 3 generators generating 3Mw each.We ensure that the kvars(leading or lagging) generated is always less than half of the kva generated to ensure a powerfactor close to unity.We supply our own process plant with an average load of 7,5Mw.The...
