IEC 60422 Mineral Insulating Oils for Electrical Equipment - Inspection and Maintenance Manual

EUROLAB laboratory provides testing and compliance services within the scope of the IEC 60422 standard. IEC 60422 provides guidance on the inspection and maintenance of the quality of insulating oil in electrical equipment.

This International Standard is applicable to mineral insulating oils originally supplied in accordance with IEC 60296, found in transformers, switchgear and other electrical equipment where the oil sample is reasonably applicable and normal operating conditions as specified in the equipment specifications apply.

This International Standard is also intended to assist the power equipment operator in assessing the condition of the oil and maintaining it in a serviceable condition. It also provides a common basis for the preparation of more specific and complete local codes of practice.

The standard includes recommendations for testing and evaluation procedures and outlines methods for oil regeneration and recovery and for decontamination of oil contaminated with PCBs.

The main changes compared to the previous edition are as follows:

• This new edition represents a major revision of the third edition to align this standard with the latest oil condition monitoring development, which includes new limits for oil parameters, suggested corrective actions in the charts, and new test methods.
• The action limits for all oil tests have been revised and changes have been made where necessary to ensure that users use the current methodology and comply with requirements and regulations affecting safety and environmental issues.
• In addition, this standard contains changes to the relevant standards since the publication of the third edition.
