4. Work Flow Chart of Erection Sequence4.1. The installation of diesel generator distribution cabinets has been completed, the ground is reliable, meets the design requirements, the general contractor, supervisor and the owner have passed the acceptance. All conditions are met. Technicians can make statements before a single commissioning.6. Quality and Technology Standards6.1 Measuring the insulation resistance 6.1.1 The insulation resistance measurement should not be less than 1MΩ;6.2 of windings Measuring the DC resistance of 6.2.1 The DC resistance between the measuring lines should not differ by more than 1% of its minimum value;6.3 windings AC withstand voltage test of windings 6.3.1 When 500V megger is used to measure, the insulation resistance value should be greater than 1m Ω. The 1000V withstand voltage test to ground power frequency is only conducted for control circuit, lasting for 1 minute; when the insulation resistance of circuit is greater than 10m Ω, 2500V megger can be used to replace it, lasting for 1 minute. The withstand voltage test should not be conducted on the 24 V control circuit of diesel engine control panel.6.4. Measuring phase sequence6.4.1 Measure the phase sequence, the label of the motor outlet terminal should be consistent with the phase sequence;
