IEEE - IEEE PC62.69 DRAFT - DRAFT STANDARD FOR THE SURGE PARAMETERS OF ISOLATING TRANSFORMERS USED IN NETWORKING DEVICES AND EQUIPMENT Organization: IEEE
Date: 2014-05-01
Description: This standard sets terms, test methods, test circuits, measurement procedures and preferred result values for the surge parameters of isolating transformers used in networking devices and equipment three types of isolating transformer are considered; mains low frequency power, high frequency power (switching mode power supplies) and signal (eg Ethernet data) the surge parameters of the isolating transformer insulation barrier covered by this standard are: - Rated impulse voltage - Input winding to output winding capacitance - insulation resistance Additional parameters for signal isolating transformers are: - Core saturation voltage-time product Purpose The main purpose of this standard is to define a series of transformer impulse withstand voltage ratings that are higher than those of IEEE Std 802.3TM [B6]1 with the intent to improve transformer insulation performance in uncontrolled environments.
