EN 60524:1993/A2:1997

Overview

EN 60524:1993/A2:1997, issued by the CLC (European Committee for Electrotechnical Standardization), is an important amendment to the original EN 60524:1993 standard focusing on direct-current resistive volt ratio boxes. This standard aligns with international requirements described in IEC 60524:1975/A2:1997 and provides specific guidelines related to the design, construction, and performance of resistive volt ratio boxes used in direct current (DC) applications.

Resistive volt ratio boxes are precision instruments used to measure voltage ratios in electrical circuits, essential for calibration, testing, and verification in both industrial and laboratory environments. The amendment A2 from 1997 ensures improved accuracy, safety, and standardization for these devices across Europe.
