How to Design System Grounding in Low Voltage Electrical Systems
This online engineering PDH course provides information on the selection, design and implementation of different grounding methods used in low voltage electrical networks.
In low voltage systems, the following are the most commonly used system grounding types: Exposed-conductive parts connected to neutral – TN, Grounded neutral – TT, Ungrounded (or impedance-grounded) neutral – IT. The objective of these three grounding systems is the same when it comes to the protection of people and equipment is the mastery of insulation fault effects.
The grounding systems are considered to be the same with respect to people’s safety against indirect contacts. Nevertheless, their usage is different depending on the low voltage electrical installation with respect to system availability and maintenance requirements. In fact, the control and monitoring equipment in buildings (electrical power distribution management systems) has an increasingly crucial role in management and dependability. These developments in dependability requirements impact the selection and design of system grounding.
This 5 PDH online course is applicable to electrical engineers who are interested in understanding the selection and operation principles behind grounding systems when designing grounding of the low voltage systems.
This continuing education course is intended to provide you with the following specific knowledge and skills:
- Familiarizing with insulation fault causes and the direct and indirect contact with live, energized elements
- Learning about the proper management of electrical hazards
- Understanding system grounding and protection of personnel
- Learning about IT, TT AND TN grounding systems and their respective implementation
- Gaining a general overview on MV-LV disruptive breakdowns inside the transformer
- Understanding neutral protection according to system grounding
- Learning about the methods for system grounding selection
