Instrument transformer
Series MT
Instrument transformer
Voltage measuring transformers to reduce the high value of the voltage to be measured to a small, safe value that is easy to handle for relays, analysers and measuring equipment.
The accuracy class indicates the maximum voltage error in the transformation ratio.
Class 0.5: error <0.5% at the indicated power.
Class 1: error <1% at the indicated power
Features
- Enclosure made of self-extinguishing V0 technical polyamide, halogen and phosphor free.
- To isolate and separate circuits and measuring equipment from high-voltage lines.
- Screw connection and pre-inserted thrust washer.
- Highly accurate transformer ratio even with voltage and current transients.
- Protects the user from access to dangerous contact parts of the winding.
