BS EN 60599:1999 使用中矿物油浸渍的电气设备.溶解和自由气体分析说明指南

This International Standard is a guide describing how the concentrations of dissolved gases or free gases may be interpreted to diagnose the condition of oil-filled electrical equipment in service and suggest future action. This guide is applicable to electrical equipment filled with mineral insulating oil and insulated with cellulosic paper or pressboard-based solid insulation. Information about specific types of equipment such as transformers (power, instrument, industrial, railways, distribution), reactors, bushings, switchgear and oil-filled cables is given only as an indication in the application notes (see annex A). The Guide may be applied only with caution to other liquid-solid insulating systems. In any case, the indications obtained should be viewed only as guidance and any resulting action should be undertaken only with proper engineering judgment.

IPC TM-650 5.5.1.3-1998 IPC-B-25 - 多用途测试板-1组和2组

This specification covers qualification and performance of rigid printed boards. The printed board may be single-sided, double-sided, with or without plated-through holes. The printed board may be multilayer with plated-through holes and with or without buried/blind vias. The printed board may be multilayer containing build up HDI layers conforming to IPC-6016. The printed board may contain active embedded passive circuitry with distributive capacitive planes, capacitive or resistive components. The printed board may contain a metal core or external metal heat frame, which may be active or nonactive. Revision level changes are described in 1.6.
