High Impedance Differential protection system versus Low Impedance Differential protection system

2015 68th Annual Conference for Protective Relay Engineers, 2015
High Impedance Differential (HID) is a classical busbar protection system that has provided a high degree of reliability in worldwide use over the past six decades. During the past five years, however, there has been a growing movement to replace HID with state-of-the-art numerical Low Impedance Differential (LID) protection systems.

Differential Protection for Converter Transformers

12th IET International Conference on Developments in Power System Protection (DPSP 2014), 2014
This paper will present differential protection schemes used for special Converter Transformers. These transformers are typically used to feed MV drives, power electronic or FACTS devises. Converter transformers are industrial power transformers which may have phase angle shift different from standard 30o or a multiple of 30o.

On protection and vertical product differentiation

Regional Science and Urban Economics, 2000
Abstract This paper analyzes the effects of trade barriers on the degree of vertical product differentiation in a model of spatial competition with two interdependent markets. It is shown that with specific trade barriers, firms produce the same product variety, always provided that the level of protection is sufficiently high. When there is trade in
