TS 7032

TS 7032 is an electrotechnical terminology standard for instrument transformers, bringing together the terms and definitions used in this field. It focuses in particular on the common and general terms associated with current transformers and voltage transformers, helping to align meaning across measurement circuits, protection applications, and technical documentation.

Why instrument transformers form a distinct terminology area

In general technical context, instrument transformers are used to convert high current or high voltage into more manageable values for measuring instruments and protective equipment. Current transformers scale current, while voltage transformers scale voltage, allowing meters and relays to be used without direct connection to the primary power circuit. Clear terminology matters because it supports consistent measurement practice, correct interpretation of ratings, and unambiguous communication in power-system engineering.

Conceptual coverage in this standard

• General and common electrotechnical terms
• Terms related to current transformers
• Terms related to voltage transformers
• Definitions used within the instrument-transformer domain

Based on IEC 50-321:1986 and identified here as equivalent, TS 7032 is a vocabulary document rather than a product-performance or test-method standard. Its value lies in fixing what the terms mean, so specifications, catalogues, training material, and technical correspondence can use the same language. For engineers, technicians, and documentation teams working with instrument transformers, that shared vocabulary is often as important as the hardware itself.
