ZERA - devices and systems for producing, measuring, testing and calibrating electrical quantities

Stationary and mobile Instrument Transformer Testing Systems

Our Instrument Transformer Test Systems (ITTS) are suitable for CT/VT testing according to IEC standards. The system can be operated manually and automatically. If required a mobile use is possible.

Sources

Basically the kind of generation and the required frequency is the decisive factor to choose the suitable source.
