Abstract:

Capacitor voltage transformer (CVT) is the most widely used type of voltage transformer in Shandong power grid. With the continuous expansion of power grid scale, higher requirements are put forward for the insulation performance and operation stability of CVT. At present, the dielectric loss tandelta is generally recognized as an important characteristic parameter to characterize the overall insulation status of CVT, but this traditional detection and evaluation method can not effectively evaluate the insulation status of CVT. To solve this problem, a CVT insulation state evaluation method based on active power loss is proposed in this paper, and the effectiveness of this method is verified by two examples. And this method can be used as a powerful complement to the conventional insulation detection parameter tandelta.
