Successful SIL test under wet conditions for our 800kV RC Divider

This Low Power Voltage Transformer (LPVT), boasting an accuracy class of 0.1 - WB2 (as per IEC 61869-1 Ed2), accurately measures voltages across a bandwidth of o-20000 Hz, offering utilities a detailed picture of the harmonic content within their Extra High Voltage (EHV) grid.

The test took place at LCOE High Voltage Laboratory placed in Getafe (Spain) in an arrangement that emulates the final mechanical installation at the end user substation. The large dimensions of the DUT as well as the high stress it places on testing equipment were the major challenges of this phase of testing.
