Capacitive voltage sensor VSO 38

The sensor is a capacitive divider. High-voltage capacity consists of special electrodes embedded in epoxy casting material. Low voltage capacity is a capacity output cable. It comes in a length of 12 m (length can be customized, but it is necessary to realize the effect of the total cable length to nn capacity and output voltage). 

As acceptance secondary voltage 138 V was chosen to load 1MOhm. The voltage can be adjusted by additional capacity according to user requirements. Output cable is protected by a built-in switching spark gap 470V levels.
