You asked: What is protection and control?

What is protection control and metering?

Installs, maintains, troubleshoots and repairs relay and control equipment in electrical sub-stations e.g. protective relays, instrument transformers, meters, recording instruments, controls (breakers, regulators, capacitors, etc.)

What do Protection and Control engineers do?

P&C Engineers are responsible for supporting or leading substation engineering project teams, with the development of protective relay design including relay selection, relay one line diagrams, schematics, SCADA design, etc.; transmission and distribution system modeling (ASPEN); and protective relay settings …

What is control and protection?

Protection & Controls (P&C) engineering is a division of electrical power engineering that deals with the protection of electric power systems for power generation, transmission, and distribution.

What is power system protection and control?

Power system protection is a branch of electrical power engineering that deals with the protection of electrical power systems from faults through the disconnection of faulted parts from the rest of the electrical network. … The devices that are used to protect the power systems from faults are called protection devices.

What is protection electrical?

Protection is provided by fuses or other suitable automatic circuit-interrupting devices for preventing damage to circuits, equipment, and personnel by abnormal conditions, such as overcurrent, high or low voltage, and single phasing.

Why is fault protection essential?

Grounding, bonding and ground fault protection are vital to decrease shock hazards to personnel during a ground fault such as when a current-carrying conductor’s insulation fails or inadvertently faults to ground.

What does a relay engineer do?

Relay Engineer Responsibilities

Implement utility network monitoring and alarming system which include outage notification and restoration. Used AutoCAD to design a transformer sensor box, recloser cabinet and to document current lab electrical layout.

What do you mean by switchgear?

What is switchgear? Electrical switchgear refers to a centralized collection of circuit breakers, fuses and switches (circuit protection devices) that function to protect, control and isolate electrical equipment.

What do you mean by system protection?

Protection refers to a mechanism which controls the access of programs, processes, or users to the resources defined by a computer system. We can take protection as a helper to multi programming operating system, so that many users might safely share a common logical name space such as directory or files.

What are the types of protection scheme?

Protection Schemes

  • Overcurrent Protection Scheme.
  • Differential Protection Scheme.
  • Distance Protection Scheme.
  • Directional Protection Scheme.

What are the two types of protection?

It is a usual practice to divide the Types of Protection scheme into two classes viz. primary protection and back-up protection.

What is primary 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 main protection is provided in each section of an electrical installation.

What is circuit breaker types?

There are three basic circuit breaker varieties: standard breakers (which include both single-pole and double-pole circuit breakers), ground fault circuit interrupter circuit breakers (GFCIs) and arc fault circuit interrupter circuit breakers (AFCIs).
