Insulation transformer unit UT type

拡大

 

UT10P66 type
This device is installed on the service wires of carrier transmission system substation remote monitoring equipment and communication breakers, etc., to protect people and equipment from ground potential rise that may occur in the event of a substation accident, etc., or irregular voltage such as lightning surges, that may have been induced along link lines, as well as to prevent damage to line insulation.

UT10S11 type
This device is used to protect people and equipment from irregular voltage caused, for example, by potential rise in the event of a feed circuit earth fault, or by lightning surges induced into the transmission circuits between ATS-P device code processing equipment, or other signal transmission circuits.
