GB/T 44378-2024 in English

The GB/T 44378-2024 standard, published by the Standardization Administration of China on August 23, 2024, and set to be implemented from March 1, 2025, introduces a comprehensive method for particle counting and size classification in insulating liquids. This standard is designed to provide precise guidelines for evaluating the purity and quality of insulating fluids used across various electrical equipment and systems.

Particle contamination can significantly affect the performance and lifespan of insulation systems, leading to potential failures if not properly managed. The GB/T 44378-2024 standard aims to address these issues by offering a standardized approach for quantifying particulate matter in insulating fluids through advanced analytical techniques.

The methodology outlined in this standard includes detailed procedures for collecting fluid samples, preparing them for analysis, and conducting particle count measurements. It also specifies the criteria for classifying particles based on their size, which is crucial for determining their potential impact on insulation integrity.

By adopting GB/T 44378-2024, manufacturers, testing laboratories, and maintenance organizations can ensure consistent quality control practices, thereby enhancing safety, reliability, and efficiency in the use of electrical equipment that relies on insulating fluids.
