Description

An LT CT Metering Panel is a critical component in electrical distribution systems, designed for accurate measurement of electrical energy consumption in low-tension (LT) applications where current levels exceed the direct measurement capabilities of standard meters. It utilizes Current Transformers (CTs) to step down high currents to a measurable range for the connected energy meter.
