WM3000I

Multifunctional measuring bridge for current instrument transformers

The measuring bridge WM3000I is a multifunctional, high-precision comparator unit. It is used for comparing the secondary signal from the transformer under test (or digital information of non-conventional transformer) with a reference signal supplied by a standard transformer. It is suitable for testing conventional, electronic and non-conventional, digital current transformers.
The following standards are complied with:

• IEC 61869-1
• IEC 61869-2
• IEC 61869-8
• IEC 61869-10
• IEC 61869-14
• IEC 61850-9-2
• ANSI/IEEE C57.13
