Compare equipment nameplate data with drawings and specifications. Inspect physical and mechanical condition.
Inspect anchorage, alignment, grounding, and required area clearances. Verify the unit is clean and all shipping bracing, loose parts, and documentation shipped inside cubicles have been removed. Verify that fuse and circuit breaker sizes and types correspond to drawings and coordination study as well as to the circuit breaker s address for microprocessor-communication packages.
Verify that current and voltage transformer ratios correspond to drawings. Verify that wiring connections are tight and that wiring is secure to prevent damage during routine operation of moving parts. Inspect bolted electrical connections for high resistance using one or more of the following methods: 1.
Standard for Acceptance Testing Specifications for Electrical Power Equipment and Systems
Use of a low-resistance ohmmeter in accordance with Section Verify tightness of accessible bolted electrical connections by calibrated torque-wrench method in accordance with manufacturer s published data or Table Perform thermographic survey in accordance with Section Verify operation and sequencing of interlocking systems.
Verify appropriate lubrication on moving current-carrying parts and on moving and sliding surfaces. Inspect insulators for evidence of physical damage or contaminated surfaces. Verify correct barrier and shutter installation and operation. Test Values 3. Compare bolted connection resistance values to values of similar connections.
Investigate values which deviate from those of similar bolted connections by more than 50 percent of the lowest value. Bolt-torque levels shall be in accordance with manufacturer s published data.
In the absence of manufacturer s published data, use Table 3. Results of the thermographic survey shall be in accordance with Section 9. Insulation-resistance values of bus insulation shall be in accordance with manufacturer s published data.
In the absence of manufacturer s published data, use Table Values of insulation resistance less than this table or manufacturer s recommendations should be investigated.
Dielectric withstand voltage tests shall not proceed until insulation-resistance levels are raised above minimum values. If no evidence of distress or insulation failure is observed by the end of the total time of voltage application during the dielectric withstand test, the test specimen is considered to have passed the test. Minimum insulation-resistance values of control wiring shall not be less than two megohms.
Results of electrical tests on instrument transformers shall be in accordance with Section Results of ground-resistance tests shall be in accordance with Section Accuracy of meters shall be in accordance with Section Exercise all active components.
Inspect mechanical indicating devices for correct operation.
Verify that filters are in place and vents are clear. If the electrical test is item four, the expected result under the Test Values section is also item four. Inspect anchorage, alignment, and grounding.
Inspect air baffles, filter media, cooling fans, slip rings, brushes, and brush rigging. Use of low-resistance ohmmeter in accordance with Section Verify tightness of accessible bolted electrical connections by calibrated torque-wrench method in accordance with manufacturer s published data or Table Perform thermographic survey in accordance with Section 9.
Perform special tests such as air-gap spacing and machine alignment. Manually rotate the rotor and check for problems with the bearings or shaft. Rotate the shaft and measure and record the shaft extension runout. Verify the application of appropriate lubrication and lubrication systems. Verify that resistance temperature detector RTD circuits conform to drawings. Electrical Tests AC Induction 1.
Calculate polarization index. Machines horsepower kilowatts and less: Test duration shall be one minute. In the absence of manufacturer s published data, use Table 4.
Air-gap spacing and machine alignment shall be in accordance with manufacturer s published data. Investigate any values that deviate from similar bolted connections by more than 50 percent of the lowest value. The recommended minimum insulation resistance IR 1 min test results in megohms shall be in accordance with Table The polarization index value shall not be less than The dielectric absorption ratio shall not be less than If no evidence of distress or insulation failure is observed by the end of the total time of voltage application during the dielectric withstand test, the test specimen is considered to have passed the test.
Investigate phase-to-phase stator resistance values that deviate by more than five percent. Power-factor or dissipation-factor values shall be compared to manufacturer s published data. In the absence of manufacturer s published data these values will be compared with previous values of similar machines. Tip-up values shall indicate no significant increase in power factor.
If no evidence of distress, insulation failure, or lack of waveform nesting is observed by the end of the total time of voltage application during the surge comparison test, the test specimen is considered to have passed the test. Bearing insulation-resistance measurements shall be within manufacturer s published tolerances. In the absence of manufacturer s published tolerances, the comparison shall be made to similar machines.
Certain tests are assigned an optional classification.

The following considerations are used in determining the use of the optional classification: 1. Does another listed test provide similar information? How does the cost of the test compare to the cost of other tests providing similar information? How commonplace is the test procedure?
Is it new technology? Manufacturer s Instruction Manuals It is important to follow the recommendations contained in the manufacturer s published data. Many of the details of a complete and effective testing procedure can be obtained from this source.Most Related. Within those sections there are, typically, three main bodies of information: 1. In other cases, a number of the tests indicated as optional should be performed. What are the differences between a power ansi neta ats and a transformer?
