The utility model relates to an existing field test system of interval merging cells power factor angle uniformity belongs to the intelligent substation equipment checking field. 0.02 source merging cells tester was taken to the level analog voltage output, current output terminal link to each other with 0.05 grade of standard FT3 generating device and interval merging cells's the analog input end of awaiting measuring respectively, 0.05 the standard FT3 generating device's of level FT3 output and the interval merging cells's that awaits measuring FT3 receiving terminal links to each other, the interval merging cells's that awaits measuring ether grid side mouth with 0.02 the level takes the ether grid side mouth of source merging cells tester to link to each other. The advantage is novel structure, has realized just can testing cascaded interval merging cells's the synchronous precision of sampling not changing the field connection, has solved on -the -spot generating line merging cells and has cascaded the
