Instance When several occurrences of the same function are available
in the IED, they are referred to as instances of that function.
One instance of a function is identical to another of the same
kind but has a different number in the IED user interfaces.
The word "instance" is sometimes defined as an item of
information that is representative of a type. In the same way
an instance of a function in the IED is representative of a type
of function.
IP 1. Internet protocol. The network layer for the TCP/IP
protocol suite widely used on Ethernet networks. IP is a
connectionless, best-effort packet-switching protocol. It
provides packet routing, fragmentation and reassembly
through the data link layer.
2. Ingression protection, according to IEC 60529
IP 20 Ingression protection, according to IEC 60529, level
IP20- Protected against solid foreign objects of 12.5mm
diameter and greater.
IP 40 Ingression protection, according to IEC 60529, level IP40-
Protected against solid foreign objects of 1mm diameter and
greater.
