SIST EN 61143-1:1999/A1:1999

Overview

SIST EN 61143-1:1999/A1:1999 is a Slovenian standard that aligns with the international standard IEC 61143-1 including its Amendment 1. This standard specifies the definitions and requirements for electrical measuring instruments, particularly X-t recorders. These devices are essential for capturing, recording, and analyzing electrical and magnetic quantities in various applications, ensuring that measurements are reliable and consistent across different industries. This standard supports harmonization and quality assurance in the field of electrical measurement.

Key Topics

The key topics addressed in SIST EN 61143-1:1999/A1:1999 include:

• Definitions: Precise terminology for X-t recorders used for electrical measurement
• General Requirements: Fundamental characteristics and conditions that X-t recorders must fulfill
• Performance Criteria: Standards for accuracy, reliability, and stability
• Markings and Labels: Requirements for clear identification and safe operation of devices
• Documentation: Essential information and data that manufacturers must provide
• Amendments to Tables and References: Updates such as the removal of certain references (e.g., IEC 60414) and changes in safety symbol tables

By establishing clear definitions and aligning requirements with international practices, the standard assists manufacturers, laboratories, and end-users in achieving accurate, repeatable, and safe measurement results.

Applications

X-t recorders are widely used in various sectors where electrical and magnetic quantity monitoring is crucial. Typical practical applications include:

• Power Generation and Distribution: Monitoring voltage, current, and frequency over time
• Electrical Equipment Testing and Evaluation: Validating the performance of devices and systems
• Laboratories and Research Institutes: Detailed time-based recording for analysis and reporting
• Industrial Automation: Process control and monitoring of machinery and equipment
• Quality Assurance: Documenting compliance with regulatory and safety standards

By following the guidance provided in SIST EN 61143-1:1999/A1:1999, organizations can ensure their measurement practices are robust, traceable, and compatible with international requirements.
