Protection and Control Device Numbers and Functions
The protection and control devices in electrical equipment can be referred to by numbers, with appropriate suffix letters when necessary, according to the functions they perform.
A quick guide for ANSI relay protection codes
In this article, I combined all the main IEEE/ANSI definitions for protection elements, possible extensions, and meanings behind them. Feel free to share and spread the knowledge.
illustrates that generated IED Capability Description
The differential protection relay (SEL487E) has dedicated harmonic restraint function which blocks the relay tripping during the transformer magnetizing inrush conditions.
Relay Symbols & Device Numbers: IEC & IEEE Standards
Technical document detailing relay symbols, device numbers, and functions based on IEC 617 and IEEE C37.2 standards for switchgear.
Table of ANSI IEEE Standard Device Numbers
In North America protective relays are generally referred to by standard device numbers. Letters are sometimes added to specify the application (IEEE Standard C37.2-2008).
Files used by IEC 61850 driver.
IED Capability Description (ICD) file: Contains the IED''s settings, with the definitions of Logical Devices, Logical Nodes, reports, datasets, etc. The ICD file is generated by the IED''s
Protection Relay
In the design of electrical power systems, the ANSI Standard Device Numbers denote what features a protective device supports (such as a relay or circuit breaker). These types of
Terminologies used in Protective Relaying
A unit protection is a protective system in which the protection zone is clearly defined by the CT boundaries. Such systems work for internal faults only, meaning it will only trip the breaker if
System Configuration Language and IEDs
Apparently, there is sometimes still some confusion. Today, there are three file types defined, that apply to an IED: ICD (IED capability description) IID (Instantiated IED description) and CID (IED
