Primary & Backup Protection
The main protection or primary protection is the first line protection which provides quick-acting and selective clearing of a fault within the boundary of the circuit section or element it protects. The backup protection provides the back up to the main protection whenever it fails in operation or is cut out for repairs.

Protection schemes and zones | PPT | Free Download
The power system is protected through a zone protection scheme where the system is divided into sections, with each zone having one or more protective relays coordinated with the overall protection system. The zones are arranged to overlap so that no part of the system remains unprotected, and circuit breakers are located in the overlapped regions.

What is Primary and Back-up Protection in Power System?
Primary or Main Protection : The power system is divided into various zones of protection. For each zone, there is a particular protective scheme. If any fault occurs in a protected zone, it is the duty of the primary or main relays to act and isolate the faulty element. The principles of operation of both primary and backup protection are

6 FAQs about [Primary and backup protection in power system ppt]
What are the main and back-up protections provided at different stations?
The main and back-up protections provided at different stations and are completely independent. The system having central control can be provided with centrally controlled back-up. Central control continuously supervises the load flow and frequency in the system. The information about load flow and frequency are assessed continuously.
What is primary protection & addition protection?
Primary protection (Main protection) is the essential protection provided for protecting an equivalent/machine or a part of the power system. As a precautionary measure, addition protection is generally provided and is called Backup Protection.
What are the methods of back-up protection?
The methods of back-up protection can be classified as follows : Same breaker is used by both main and back-up protection, but the protective systems are different. Separate trip coils may be provided for the same breaker. Different breakers are provided for main and back-up protection, both the breakers being in the same station
Why is back-up protection provided?
Back-up protection is provided for the following reasons If due to some reason, the Main protection fails, the Back-up protection serves the purpose of protection. Main protection can fail due to failure of one of the components in the protective system such as a relay, auxiliary relay Current Transformer, PT, trip circuit, circuit-breaker, etc.
What is a primary protection system?
cuit element, that the zone is required to protect.Primary Protection as a rule is prov ded for each section of an electrical ins allation. However, the primary prot ction may fail. The primary cause of failure o thePrimary Protection system is enume name given to a protection which backs the prima yprotection whenever the
What is the difference between main protection and back-up protection?
When main protection is made inoperative for the purpose of maintenance, testing, etc. the Back-up protection acts like main protection. As a measure of the economy, Back-up protection is given against short-circuit protection and generally not for other abnormal conditions.
