  • Page 55 2. INTRODUCTION 2.1 INTRODUCTION The generator is of brushless rotating eld design, available up to 660V at 50Hz or 60Hz. The design, build and text procedures meet a range of British, European and international stan- dards including, BS 5000, BS EN 60034 and ISO 60034, Where applicable. The generators are tted with the PMG Pilot exciter system and an automatic voltage regulator (AVR).
  • Page 56 3. PRINCIPLE OPERATION 3.1 EXCITED-AVR CONTROLLED GENERATORS The main stator provides power for excitation of the exciter eld via the SX440 AVR which is the controlling device governing the level of excitation provided to the exciter eld. The AVR responds to a voltage sensing signal derived from the main stator winding By controlling the low power of the exciter eld, control of the high power requirement of the main eld is achie- ved through the recti ed output of the armature.
  • Page 57 The generators have been designed for use in a maximum ambient temperature of 40°C, and altitude less than 1000 metres above sea level in accordance with Bs5000. Ambient in excess of 40°C, and altitudes above 1000 metres can be tolerated with reduced ratings-refer to the factory.
  • Page 58 generator intake, particularly where the radiator cooling fan is required to draw air into the canopy. In addition the generator air intake to the canopy should be designed such that the ingress of moisture is prohibited. Preferably by use of a two stage lter. The air intake/outlet must be suitable for the air ow given in the following table with additional pressure drops less than or equal to those given in table 1 below: The generators may be tted with air f ilters.
  • Page 59 Warning! No earth connections are made on the generator and reference to site regulations for earthing must be made. In correc tearthing or protection arrangements can result in personal injury or death. Fault current curves (decrement curves), together with generator reactance data, are available on request to assist the system designer to select circuit breakers.
  • Page 60 1. Consult the genset builder. The genset builder should address the genset design to reduce the vibration levels as much as possibie. 2. Discuss, with 3. The impact of not meeting the above levels on both bearing and generator life expectancy. IMPORTANT! Important, refers to hazard or unsafe method or practice which can result in product damage or related equipment damage.
  • Page 61 5. INSTALLATION-PART 1 5.1 LIFTING Warning! Incorrect lifting or inadequate lifting capacity can result In severe personal injury or equipment damage MINIMUM LIFTING CAPACITY REQUIRED IS AS INDICA TED ON THE LIFTING LABEL. Generator lifting lugs should not be used for lifting the complete Two lifting lugs are provided for use with a shackle and pin type lifting aid, A spreader with chains, to ensure that the lift is vertical, of suitable length and lifting capacity must be used.
  • Page 62 Location dowel pins are tted to the engine ywheel. The coupling can then slide into nal location on the engine ywheel recess. The dowels must be removed and replaced by coupling bolts before the nal bolt tightening sequence. While tting and tightening the coupling bolts it will be necessary to rotate the engine cranks- haft - Generator rotor assembly.
  • Page 63 CAUTION! Care should be taken not to allow any cleaning agent to come into prolonged contact with skin. Alignment of single bearing generators is critical. If necessary shim the generator feet to ensure alignment of the machined surfaces. The sequence of assembly to the engine should generally be as follows: 1.
  • Page 64 5.4.1 INSULATION CHECK Insulation tests should be carried out before running the generator set, both after assembly and after installation on site. (see Section 7.1) IMPORTANT! The windings have been H.V. Tested during manufacture and further H.V. Testing may degrade the in sulation with consequent reduction in operating life.

  • Page 66 5.5.1 TEST METERING/CABLING Connect any instrument wiring and cabling requited for initial test purposes with permanent or spring-clip type connectors Minimum instrumentation for testing should be line to line or line to neutral voltmeter, Hz meter, load current meteting and kW meter. If reactive load is used a power factor meter is desitable.
  • Page 67 1. Run the generating set on no-load and check that speed is correct and stable. 2. Turn the STABILITY control potentiometer clockwise, then turn slowly anti-clockwise until the generator voltage starts to become unstable. The correct setting is slightly clockwise from this position ( i. E. Where the machine volts are stable but close to the unstable region).
  • Page 68 The UFRO control potentiometer sets the "knee Point". Symptoms of incorrect setting are a) the light emitting diode (LED) indicator, just above the UFRO control potentiometer, being permanently lit when the generator is on load, and b) poor voltage regulation on load, i.e. ope- ration on the sloping part of the characteristic Clockwise adjustment lowers the frequency (speed) setting of the "knee point"...
  • Page 69 The terminal box is arranged for glanding on the right hand side (or if speci cally ordered on the left-hand side) viewed from the end. Both panels are removable for drilling/punching to suit glands/or glanding boxes. If single core cables are taken through the terminal box side panel an insulated or non-magnetic gland plate should be tted.
  • Page 70 CAUTION! Reference to local electricity regulations or safety rules should be made go ensure correct earthing procedures h ave been followed. 6.5 PROTECTION It is the responsibility of the end user and his contractors/subcontractors to ensure that the overall system protection meets the needs of any inspectorate, local electricity authority of safety rules, pertaining to the site and it's location.
  • Page 71 When the remote voltage adjust potentiometer is used the link across terminals 1 & 2 must be removed. On SX440 the link 1&2 is on an adjacent terminal block. 7.2 PARALLEL OPERATION IMPORTANT! Failure to meet conditio ns 1, 2 and 3 when closing the circuit breaker, will generate excessive mechan ical a nd el ectrical stresses, resulting in equipment damage.
  • Page 72 The diagrams below indicate the effect of droop in a simple two generator system: Generally 5% droop at full load current zero power factor is suf cient to ensure KVAr sharing. If the droop accessory has been supplied with the generator it will have been tested to ensure correct polarity and set to a nominal leve of droop.
  • Page 73 generator. Adj ust 'DROOP' control potentiometer to give droop in line with above table. cloc- kwise rotation increases amount or droop. Refer to Fig. 5a of 5b for potentiometer locations. Note 1) Reverse polarity of the C. T. will raise the generator voltage with load. The polarities S1&S2 shown on the wiring diagrams are correct for clockwise rotation of the generator looking at the drive end.
  • Page 74 Danger! Service and fault nding procedures present hazards that can result in severe personal injury or death. Only personnel quali ed to perform electrical and me chanical service should carry out these procedures. Ensure engine start circuits are disabled before commencing service or maintenance procedures. Isolate any anti-condensation heater supply.
  • Page 75 The condition of the windings can be assessed by measurement of insulation resistance [IR] between phase to phase, and phase to earth. Measurement of winding insulation should be carried out:- 1. As part of a periodic maintenance plan. 2. After prolong periods of shutdown. 3.
  • Page 76 Blown Air Drying Remove the covers from all apertures to allow the escape of the water-laden air. During drying, air must be able to ow freely through the generator in order to carry off the moisture. Direct hot air from two electrical fan heaters of around 1-3 KW into the generator air inlet aper- tures.
  • Page 77 Once the insulation Resistance is raised to an acceptable level minimum value 10MΩ - the de supply may be removed and the exciter eld leads "X" and "XX" re-connected to their terminals on the AVR. Rebuild the genset, replace all covers and re-commission as appropriate. If the set is not to be run immediately ensure that the anticondensation heaters are energised, and retest the generator prior to running.
  • Page 78 If the minimum value of 1.0MΩ is not obtained, drying out must be continued and the test repeated. If the minimum value of 1.0MΩ for all components cannot be achieved rewinding or refurbish- ment of the generator will be necessary. The generator must not be put into service until the minimum value, Of 1.0MΩ...
