Abb offers with various types of mv instrument transformers and sensors. They are available in various models and they are:
1 ansi current transformers - they are available in voltage classes ranging from 0.6 kv to 34.5 kv and are offered in a variety of insulation materials including thermoplastic rubber, plastic case, polyurethane, and hydrophobic cycloaliphatic epoxy [hcep].
2 ansi voltage transformers - they are available in voltage classes ranging from 0.6 kv to 34.5 kv and are offered in a variety of insulation materials including thermoplastic rubber, polyurethane, and hydrophobic cycloaliphatic epoxy [hcep].
3 iec voltage transformers - the transformers can be installed in any position within a cubicle-type or cellular-type mv switchboard. Transformers can be equipped with fuse, introduced in the primary winding, or without fuse.
4 ansi specialty application transformer products - specialty combination cts and pts for metering and control power are available in voltage classes ranging from 0.6 kv to 34.5 kv. The transformers can be used in various metering packages for switchgear and utility applications.
5 iec current transformers - the basic construction part of the transformer is the epoxy body, the primary winding, secondary winding and the magnetic circuit. The transformers may be installed in any position inside the switchboard.
6 sensors - new solution for measuring currents and voltages needed for protection and monitoring in medium voltage power systems.
