Kilovolt meter KV4080

Kilovolt meter KV4080

КV4080 is digital measuring, fully programmable device from series 4080, designed on basis of microcontrollers. The device is used to measure middle/high voltage in electrical substations and power plants. It measures the secondary voltage of a voltage transformer with nominal secondary voltage 100VAC (or other voltage in range of 60-220VAC) and shows the primary voltage in kilovolts. KV4080 is powered by the measured voltage. The unit is designed to be mounted on boards in control rooms of electrical substations.

user manual

KV4080 is offered in following variety*:

- basic option, without any relay contacts, user menu is not code-protected
R there are three relay contacts that provide remote signalization, acting when certain programmed voltage levels are reached
C code-protected user menu
X user is not allowed to change device settings
* - Every option can be ordered in any combination with other options, excluding versions “C” and “X”.
