Instrument Transformers & Sensors

Current and voltage measurements from 0.6 kV to 48 kV for the protection and monitoring of medium voltage power systems.

The range of electric values in power supply systems is very extensive. This is why it is necessary to match the respective currents and voltages to the values appropriate to connected measuring, protection, and control instruments.

ABB manufactures medium voltage instrument transformers according to ANSI, IEC, GOST, GB, BS and DIN standards.
 

ANSI instrument transformers for indoor applications are available in voltage classes ranging from 0.6 kV to 35 kV.
ANSI instrument transformers for outdoor applications are available in voltage classes ranging from 0.6 kV to 34.5 kV
Current and voltage measurements for the protection and monitoring of low and medium voltage power systems
Current and voltage measurements from 15 kV to 34.5 kV for the protection and monitoring of medium voltage power systems
