Substation Relay Protection Comparison Table Diagram
Substations Volume XI Relaying
Depending on the fault characteristics of the line in question, the relay engineer may use any of the above relay protection schemes for the protection of phase and ground faults on a transmission line.
Power System Protective Relays: Principles & Practices
As the protected components of the electrical systems have changed in size, configuration and their critical roles in the power system supply, some protection aspects need to be revisited (i.e. the use of

Protection Relay Schematic Overview
It depicts multiple line differential protection relays, distance protection relays, transformer protection relays, bus differential protection relays, and other monitoring devices connected to control systems.
Substation Protection Overview
Provide current diferential protection for up to five windings with an adaptive-slope percentage restraint for transformers at power plants, transmission substations, distribution substations, and industrial
Protective Relay Basics
Traditionally, protective relays were electromechanical devices that utilized induction disk, coils, contacts, and solenoid elements to determine protective characteristics.
Chapter 12: Protection Schemes and Substation Design Diagrams
This chapter considers the combination of relays required to protect various items of power system equipment, plus a brief reference to the diagrams that are part of substation design work.
Distribution Automation Handbook
The selectivity diagram is a set of specific time/current curves which shows all the time/current curves, that is, the operating characteristics of the relays of the concerned chain of protection relays.
Protection and Substation Control
Combined feeder relays for protection, monitoring and control Mixed use of the different relay types is readily possible on account of the uniform operation and communication procedures.
