3 Overview
Transformer load box is a multi-measurement values during calibration transformers, analog load to be corrected transformer
appliance. Load boxes usually have impedance and impedance transform two structural types.
Impedance load box consists of resistive and inductive components, principle circuit shown in Figure 1. Current transformer load box by the impedance
Cells in series, shown in Figure 1 (a); voltage transformer load box consists of parallel admittance unit, shown in Figure 1 (b).
