Adaptation to different applications

The IED has a pre-defined configuration and can be used in a wide range of applications. This
is done by means of choice of functionality from the comprehensive function library in the IED.
The IED can be used in a wide range of applications. This is done by selecting from the
comprehensive function library in the IED. A selection of common applications are described
below.
• Application 1: Two-winding HV/MV, Y/Δ-transformer; HV:solidly earthed, MV:high
impedance earthed
• Application 2: Two-winding HV/MV, Y/Y-transformer; HV:solidly earthed, MV:high
impedance earthed
• Application 3: Three-winding HV/MV1/MV2, Y/Y/Δ- transformer; HV:solidly earthed,
MV1:solidly earthed, MV2:high impedance earthed
• Application 4: Three-winding HV/MV1/MV2, Y/Y/Δ-transformer; HV:solidly earthed,
MV1:solidly earthed, MV2:solidly earthed
