15 Feb 2013 The manufacturer. ABB AB. Components. SE-771 80 LUDVIKA. Sweden. Hereby declares that. The products. On-load tap-changers, type UBB with motor-drive mechanisms, types BUE and BUL comply with the following requirements: By design, the machine, considered as component on a mineral oil filled
autotransformers and to phase-shifting transform- ers (PsT). where the tap winding and therefore the. OLTC is inserted in the windings (high-voltage or low- voltage side) depends on the transformer design and customer specifications. 4 . mr KnOwLedge Base.

Since MR is the first and the sole manufacturer of on-load tap-changers that has had the VV and VR on-load tap-changers certified in accordance with 94/9/EG. (ATEX) guidelines (in conformance with IEC and NEC 505 in North America). Advantage: Precise switching procedures even under the most extreme of conditions.

Abstract. This is a Master's thesis in Applied Physics. The primary topic of the thesis is to develop an accelerated life test for the moving contacts in on-load tap changers, simulating the wear of 30 years use regarding oxidation and coking. The secondary topic is to examine the surface structure of silver contacts to aid in
