Designed specifically as a replacement card for vertical hardware frames, this \u003cstrong\u003eCT\/VT Module\u003c\/strong\u003e handles precision simultaneous acquisition of both current and voltage metrics from major power system lines. The hardware is defined by a \u003cstrong\u003eStandard 4CT\/4VT with enhanced diagnostics\u003c\/strong\u003e layout, integrating four current transformer (CT) channels and four voltage transformer (VT) channels onto a unified circuit assembly. This enables the parent relay to continuously analyze three-phase power variables plus an additional auxiliary channel for neutral or zero-sequence parameter tracking. Engineered to cooperate directly with an \u003cstrong\u003eenhanced front panel with Chinese display and user-programmable pushbuttons\u003c\/strong\u003e, the \u003cstrong\u003eUR-8LV\u003c\/strong\u003e feeds vital electrical network samples to the CPU for localized protection logic execution, comprehensive power metering, true RMS evaluation, and active
