PV System Protection

All electrical systems require that forms of circuit protection be applied wherever necessary and when it is best practice to do so. Properly designed circuit protection safeguards electrical equipment and people against a fault, for example when carrying out any work on the system, such as troubleshooting. Relevant local and international standards, local service rules and the network operator’s regulations should provide the basis for the system’s overall protection design.

This course will teach you how to:

• Calculate the DC overcurrent protection sizing requirements
• Select appropriate DC disconnection devices
• Determine the AC overcurrent and disconnection devices required 
• Identify system earthing, lightning protection, and RCD requirements to protect equipment
