OUR 3 pHASE KATOLIGHT GENERATOR KLM3-55-540 Serial #LM355261 is not working properly. The three lights that tell you when you have reached the correct RPM are not working. What do we do.?

Gas, Diesel, Propane or Natural Gas. Make sure it has fuel, make sure it has compression, make sure it has ignition. Here is the link to the distributor for local service. These things always fail when you need them the most.

id guess you need to connect with the makers for that stuff. its an unknown brand in the usa https://www.google.com/search?q=PARTS+FOR+KATOLIGHT+MODEL+L45FPG4&rlz=1C1CHBF_enUS757US757&oq=PARTS+FOR+KATOLIGHT+MODEL+L45FPG4&aqs=chrome..69i57j33i160.495j0j4&sourceid=chrome&ie=UTF-8

Have you tried google as there are lots of manuals available online if you search for them

When there is only one ammeter in the three-phase circuit and the three-phase current needs to be monitored, a start switch is needed to achieve this function. For example, three-phase switch, at least three knobs move position, switch panel marked which line name, if you want to monitor which line, you can dial the knob to the corresponding name, the ammeter will show the corresponding line current.

Hi Bill
I may be wrong here......
But I've been around Electricity for a long time.
Have Never seen a device that does phase conversion.
A Building site or home will either have Three Phase or Single Phase Power Available
BUT...A portable (Hired) generator could be "three phase" and you could use any one of those phases individually or all three phases.

I have 3 Phase supply to my house!
But I use 230 volt Single Phase for appliances.
My Bore Pump uses a 3 Phase Motor,
(so with a voltmeter it would read about 440 vAC to the pump motor).
Some Further Info:
A GENERATOR is basically a motor used the opposite way. Rotate a motor and it Generates.
The Phases refer to the THREE Windings in the supplying generator in your suburb.
A Large Magnet passes each winding in sequence giving you the three ripples in the supply.
Our houses can choose to have 1 Phase or Three Phases from the street when you set up your electric supply.
So... to confirm, look at the wires on the supply poles to the premises. Usually three in our area (Oz)
Most people are not aware that a car Alternator is actually three phase. The Rotor is the magnet that rotates.
The only difference with an Alternator is that each "Phase" is connected to 2 Diodes (6 total) to convert the three phase to DC to charge the vehicle.
The Regulator controls the voltage to the Rotor, thereby controlling the output.
So.... An Alternator could in theory supply 3 Phase in a mobile generator. Custom Made. Constant speed would determine the frequency of 50Hz or 60Hz.
Not sure what country you are in

Hope this Helps or gives you food for thought!


Three phase electric power

If you are measuring unbalanced voltage when the unit is running but unloaded, the problem most likely is in the generator windings. One of the windings could possibly be shorted or failing.

Miller welders are great. I've been around them a long time as an electrician in the mines years ago. They make a 3 phase model and a motor gen type too. They are both good welders in my opinion.

You need a e 3 phase generator to run a 3 phase pump first of all. Check to see that the generator is three phase. Most are not.

Does your generator is single phase generator set or three phase four wire generator? Why your generator set is 110V at full load, it should be 220V or 240V to generator electricity. If it is used for industrial equipment, it should be 380V, 400V, 440V, etc.
