How to Design System Grounding in Low Voltage Electrical Systems
In How to Design System Grounding in Low Voltage Electrical Systems, you'll learn ...
- Theory and selection principles behind system grounding
- TN, TT, and IT grounding systems and their implementation
- Insulation fault causes
- Relevant safety standards and codes
Overview
Commonly used system grounding types in low voltage systems are exposed-conductive parts connected to neutral (TN), grounded neutral (TT), and ungrounded (or impedance-grounded) neutral (IT).
The objective of these three grounding systems is identical regarding the protection of people and equipment with regard to mastery of insulation fault effects. They are considered to be the same with respect to the safety of people against indirect contact. But the same is not necessarily true for the dependability of the low-voltage electrical installation with respect to system availability and maintenance requirements.
Electrical systems are subjected to increasingly exacting requirements in factories and buildings. Also, 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. It needs to be kept in mind that the issue with service continuity (keeping a sound network in public distribution by disconnecting consumers with insulation faults) played a role when system grounding first emerged.
This course is suitable for electrical engineers with a desire to understand theory and selection principles behind system grounding. Presented details cover issues related to the technical implementation of different grounding methods used in low-voltage electrical networks.
Upon successful completion, engineers will be able to address different grounding types used in low voltage networks, selection and operation practices, and important considerations that need to be addressed when designing grounding of low voltage systems.
