A real universal device for protection with LPITs (Low Power Instrument Transformers)! SIPROTEC 7SY82 is designed for the connection of LPITs. The new LPIT input design makes the SIPROTEC 7SY82 a universal protection device for almost all LPITs according to IEC 61869. Coupled with our Greenwood-Power LPIT sensors, HV Power offers a full range of products and expert advice.

LPIT sensors are typically a lower cost alternative to traditional CTs and VTs, taking less space and having better accuracy and range. For 11/22/36 kV RMU applications the use of LPIT's offers many advantages. Talk to us today to learn more.
