Family of Arteche KA High Voltage Combined Instrument Transformers

Combined instrument transformers contain a current transformer and an inductive voltage transformer within the same body.

Thus they are used in the same applications as their respective independent transformers; they separate meters, counters, relays, etc., from the high voltage circuit, and provide a scaled replica of the current and voltage in the HV line.

Combined transformers are suitable for use in substations where space or installation costs make using independent Transformers difficult.

• Ideal for installation at metering points due to their very high accuracy class, both in current and voltage.
• Suitable for the discharge of high-voltage lines and capacitor banks. 
• Excellent frequency response; ideal for monitoring power quality and measuring harmonics.
