Criteria

Under the ZC,ZY standard to test the marine generator in the rated power, and overloading power.

Item

The generator Idle speed runnning 10m under rated power, then change the overloading power, every period to record the power, frequency, current etc.

Parameters.

Conclusion

During the three times of testing, under 1500rpm, 50HZ, rated

power, there is no leaking, the system is qualified for performance.

Sea water pump.

Full documents: operation manual, qualified card, parts catalog, packing list, nameplate for engine and alternator.

Generator surface inspect

before test

The seeing inspection includes: nameplate datas, welding quality pipe no leaking,

starting system and connecting wire is correct.

Generator --Alternator insulation resistance

Testing the insulation resistance between each separate electrical return circuit to earth and all return circuits, all is tested by mega-gauge, during the test, all the semi-conductor device and capacitors had been dismounted, each switch is open

situation. All the datas results are recorded correctly when the mega-gauge stable.

Generator starting performance test

Under the environment no less than 5℃, cooling water and lubricant no pre-heating,

the generator could start smoothly, 6 times starts, all the 6 starts are qualified, each starts time no more than 1minute.

Generator running testing

After the engine starting, adding speed up to the rated speed 1500rpm gradually, no un-normal noise, alternator bearing temp. Is normal, engine no leaking, alternator,

engine working all in normal case.

Remote control monitor

Checked all the datas in the regulated range.

Checking no-loading voltage

setting range

In the rated power factor, rated frequency, during the automatic and manual operation

case, tested the voltage is in the normal range.

Generator protection device testing

Starting the generator set,adjust the speed to rated speed 1500rpm under

no-loading, after it is steady, up to the speed slowly to the alarm value, then speed alarm works; the same test for water temp.sensor, Oil temp. Sensor, And oil press sensor, they all make alarm working.

Generator sudden add/unloading test

The voltage, frequency and steady time all in the normal range, during do the test sudden adding then sudden unloading, the voltage and frequency the curve changed

according, then recover.

Generator Transient state voltage changing rates and

steady time

Generator Transient state voltage changing rates and steady time all in the field standard. Because marine generator capacity is small, when loading changing, it will

makes the end voltage changed largely, it should be make sure a stable voltage.

Generator loading test

To test the Generator operating under rated working cases, after 10 minutes running under no-loading, change the loading, every period recorded datas fpr power,

frequency, current all in the requirements range.
