Section 3 1MRK 502 048-UEN A Analog inputs Section 3 Analog inputs Introduction Analog input channels in the IED must be set properly in order to get correct measurement results and correct protection operations. For power measuring and all directional and differential functions the directions of the input currents must be defined in order to reflect the way the current transformers are installed/connected in the field ( primary and secondary connections ).

There is a BLOCK input signal, which will disable the operation of the function, in the same way the setting Operation: On/Off does. That means that, upon activation of the BLOCK input, all 32 CMDBITxx outputs will be set to 0.

IEEE 1686 Standard for Substation Intelligent Electronic Devices (IEDs) Cyber Security Capabilities Intelligent electronic device I-GIS Intelligent gas-insulated switchgear Instance When several occurrences of the same function are available in the IED, they are referred to as instances of that function.
Page 723 Section 22 1MRK 502 048-UEN A Glossary OLTC On-load tap changer OTEV Disturbance data recording initiated by other event than start/pick-up Over-voltage Overreach A term used to describe how the relay behaves during a fault condition. For example, a distance relay is overreaching when the impedance presented to it is smaller than the apparent impedance to the fault applied to the balance point, that is, the set reach.

Signal matrix tool within PCM600 Station monitoring system SNTP Simple network time protocol – is used to synchronize computer clocks on local area networks. This reduces the requirement to have accurate hardware clocks in every embedded system in a network.
