HIGH-VOLTAGE MEASUREMENT DEVICE

摘要

A high-voltage divider can be used as a portable or an in-situ device for measuring high voltages under live line conditions, the divider consisting of a high-voltage resistance (42) with a first end (46) connectable to the voltage to be tested or measured and a second end opposite the first end; a low voltage resistance (44) having a first end connected in series with the second end of a high-voltage resistance, and a second end (47) connectable to earth; and a controlling means (43) for controlling the electrical stress within the divider; the controlling means may also mitigate the effect of capacitive coupling.
