Bearing Temperature - Measure/Record
Bearing temperature detectors are optional on all SR4B generators. These detectors are 100 ohm resistance temperature detectors. Bearing temperature detectors are used with equipment that has been provided by the customer in order to measure the bearing temperature. Bearing temperature detectors may help to prevent premature bearing failure.
Power Factor Check
The power factor of a system can be determined by a power factor meter or by calculations. The power factor can be calculated by dividing kW by kVA. Power factor is expressed is expressed as a decimal.
Electrical Connections - Check
Check all exposed electrical connections for tightness.
Check the following devices for loose mounting or physical damage.
Check all lead wires and electrical connections for proper clearance.
Generator - Clean
When servicing or repairing electric power generation equipment:
Failure to do so could result in personal injury or death. Make sure residual voltage in the rotor, stator and the generator is charged.
Space Heater - Check
An SR4B generator is capable of operating in high humidity conditions without problems. However problems can occur when the generator is idle and the surrounding air is warmer than the generator. Moisture can form on the windings that will result in poor performance from the windings. Moisture can also result in damage to the windings. Whenever the generator is not active, ensure that the space heaters are in operation.
Walk Around Inspection
A visual inspection should be initially directed at the areas that are most prone to damage and deterioration. The most prone areas to damage and deterioration are listed below.
