Overview

The 2767 automatic current and voltage transformer test set is a modern, fully automatic instrument for fast, accurate measurement of instrument transformer errors. Increasingly severe quality control requirements call for a higher degree of operating comfort and absolute reliability of the measuring equipment employed. Based on the latest design technology, this instrument sets new standards of quality, reliability, convenient operation and simple maintenance. Its measurement ranges for current/voltage errors, phase displacement and current/ voltage excitation are fully up to international standard requirements. This measuring instrument has been tested by PTB (Physical Technical Federal Authority) in Germany. It fulfills all requirements according to the PTB test rules for measuring instrument transformers and is approved for calibration.

Features

• Current and voltage transformer measurements with a single instrument
• Fully automatic measurement and digital display of current/voltage ratio errors, phase displacement, test current and voltage
• Measurements are possible on instrument transformers of practically any primary and secondary current and voltage ratings
• Test & standard transformers may have different ratios
• Different transformers can be tested using one single standard transformer
• Different standard and test transformer ratios are matched without use of an external divider
