CONTENTS

A. Phase SequencePhase sequence of these generators are U→V→W regardless of rotating direction ofprime mover.Please connect all cables as shown in below figure 1.

Generator Side

※ MSBD : Main Switch Board

B. Manual SynchronizingPlease be careful at synchronizing of each generator during on board test or normaloperating as follows.

1) Check that incoming generator voltage level and frequency in its no-load condition is correct.2) After rotating the synchronizing switch to the "ON" position, please check the condition of the synchroscope pointer, and adjust the speed of the incoming Engine/Generator until it is rotating slowly to clockwise direction (no more than 1 revolution / 20 seconds).3) The incoming generator breaker should be closed as close to the 12 o'clock position as possible.

WarningIf generator breaker is closed at conditions other than the above, thegenerator excitation system (Diodes, Varistors, Transformer… ) & rotoror stator can be damaged by transient reactive current.

1 TemperatureRise Test

The generator will be operated withrated current until the temperature of eachsection are saturated according toIEEE115.Temperature rise of each winding will bemeasured by resistance method.

Stator : ＜107℃Rotor : ＜112℃(Based on water inlet temp.: 38℃)

Type Test

2 Over currentTest

The generator will have to withstand50% excess of rated current for 30seconds after temperature rise test.

Without damagevisually Type Test

3 Over speed Test

Over speed test will be carried outfor 120 seconds with 1.2 times therated speed under no excitationcondition.

Without damagevisually

4 DielectricStrength Test

The test voltage with commercialfrequency will be applied to eachwinding for 60 seconds.

Stator : 14,200 VRotor : 1,500 V
