ASU-VEI Visit

On 2 November 2016, a series of tests of the UPO2-03.05.00-UHL1 facility the connecting device together with a 420 kV bushing (drawing 686354.603) successfully went in the volume of complete acceptance tests – one minute test voltage, full and chopped lightning impulse, switching impulses, prolonged subjection to alternating current - in the measuring circuit disconnection fault mode of the measuring tap of the high-voltage bushing.

Dmitry Ivanov, Head of Test Center managed the tests. Vladimir Ustinov, Deputy Quality Director, Pavel Kiryukhin, Deputy Chief Designer and Alexander Krayachich, ASU-VEI representative were present at the tests.

Connecting device UPO is a specialized contact device designed for delivering measuring tap leakage current to an external measuring device, also for grounding leakage current and built-in protection of the measuring tap of the high-voltage bushing in case of sudden disconnection fault after UPO and high-voltage pulse surges happening at lightning and switching loads. It can be applied with various systems of diagnostics.
