Spring-operated impact-test apparatus and its calibration

This document specifies the technical requirements and procedures for the design, construction, and calibration of testing equipment used to generate switching impulse waves. It defines the necessary characteristics for the power supply, control mechanisms, and measurement systems to ensure the accuracy and repeatability of high-voltage impulse tests. The standard outlines the methodology for calibrating the test circuit parameters, including wavefront time and tail time, to meet specified tolerances. It provides guidelines for safety and operational practices during the setup and execution of switching impulse tests on electrical components and systems. The calibration process ensures that the test device produces waveforms consistent with international testing protocols. This reference is essential for laboratories and manufacturers conducting high-voltage testing to verify the performance and reliability of equipment under transient overvoltage conditions.
