Ti Grounding System
Smart solutions overview of street light system in TI grounding system
There are many of electrical equipment which can be accessed by the public; however, some of them cannot be physically controlled by the operator. One of them is street light system which needs to be protected in order to prevent shock hazards under the fault conditions. Generally, street lighting systems are distributed in a large area including urban and sub urban. If fault happens, the metal case of these systems might raise a potential hazard which could lead to expose people to shock hazards. The typical protections are bonding and grounding to reduce the risk to an acceptable level. This technical literature review will be based on an IEEE paper titled “Electrical Safety of Street Light Systems” by G. Parise, L. Martirano, and M. Mitolo (2011) [1]. This will be demonstrated firstly by explaining the terms and content involved, secondly by discussing the work in the paper and finally presenting the contribution of the paper and the key learning point. In this article, the authors organize the content in eight sections. In the first five sections, the authors present the street lightning system in general, the protections used, and variation of street lighting system according to the grounding systems applied. In section six, the authors describe an example in US. The main content is in section seven where the authors explain about proposed solutions which mainly regarding to improve TI system. Finally, the authors put the conclusion and suggesting the future area of research.
Street lighting systems are a common case of distributed low-voltage load in wide areas. It usually protected by the same devices. Electrical utilities are commonly owned and operate this system. IEC 60364 [2] has set the standard of Class II to be used in street lighting systems. The purpose is to protect the systems against indirect contact. The term of Class II in here include the wiring systems, the light
