BS EN 61237-1:1995 is a British and European standard titled "Insulators for overhead lines with a nominal voltage above 1000 V - Part 1: Ceramic or glass insulator units for a.c. systems - Definitions, test methods and acceptance criteria."
This standard specifies the definitions, test methods, and acceptance criteria for ceramic or glass insulator units used in overhead power lines with a nominal voltage above 1000 V. It applies to insulators used in AC (alternating current) systems.
Here are some key points covered by BS EN 61237-1:1995:
Definitions: The standard provides definitions and terminology related to ceramic or glass insulator units used in overhead power lines.
Test Methods: It specifies the test methods to evaluate the performance of insulator units, including mechanical tests, electrical tests, and environmental tests. These tests assess factors such as mechanical strength, electrical withstand capability, and resistance to environmental conditions like temperature, humidity, and pollution.
Acceptance Criteria: The standard establishes the acceptance criteria based on the test results. Insulator units must meet these criteria to ensure their suitability for use in overhead power lines.
Marking: BS EN 61237-1:1995 also addresses the marking requirements for insulator units, including information that should be provided on the insulators to identify their characteristics and compliance with the standard.
It's worth noting that standards are periodically updated, and there may be newer versions or revisions available. Therefore, it's advisable to consult the latest version or any subsequent amendments to ensure compliance with current standards and regulations.
