Current Transformer Comparator
Supports CTs, ECTs, and Digital CTs
Compatible with Existing CT/VT Test Systems
The current measuring comparator WM3000I is a high-precision device for comparing secondary outputs from a current transformer under test (or digital output of Electronic CTs or Digital CTs) with a reference signal supplied by a standard transformer primary. The resulting error value will be displayed as ratio error and phase error on the screen. The operation of the comparator will be performed via an integrated 10.1” capacitive touch screen or controlled by PC software. The WM3000I is compatible with existing systems, like Knopp, and exports a data output for active database systems.
Multifunctional Measuring Bridge WM3000I
The current/voltage measuring bridge WM3000I is a high-precision comparator unit for comparing secondary signal from transformer under test (or digital information of non-conventional transformers) with a reference signal supplied by a standard device. The resulting error value will be displayed as ratio error and phase displacement on the screen. In general, the operation of the measuring bridges will be performed via integrated 10.1” capacitive touch screen. Optionally control and read-out of the measuring values can be performed via integrated interfaces and PC.
