CTPT.1002F Current & Protection Transformer Analyser

The CTPT.1002F is a professional CT/PT analyser designed for both laboratory and field applications, offering comprehensive testing functions for current transformers (CTs) and potential transformers (PTs).
It features a powerful automatic V–I characteristic test engine, large-capacity memory, built-in micro-printer, and PC connectivity for generating complete IEC/IEEE-compliant reports.
Its ergonomic control panel and automated software reduce operator workload and enable single-operator testing in demanding environments.

Key Features
