PD-free, right from the start
“It is quoted in all of the international standards that partial discharge has to be below a given level, therefore it is a parameter we have to check to verify the insulation condition in bushings and windings.”
(Michael Jay, Chief of Test for Power Transformers, GE Grid Solutions)
GE Grid Solutions produces high-voltage conversion and generator transformers at its factory in Stafford (England). After final assembly, factory acceptance testing (FAT) is performed to check all transformer functions.
The company considers partial discharge (PD) measurement to be absolutely essential among the tests performed to identify quality issues that need to be dealt with before the transformers are shipped to customers.
Find out why GE Grid Solutions relies on our MPD 600 and PDL 650 to measure and localize PD in bushing and winding insulation during its factory acceptance tests.
