The Intelligent Electronic Device (IED) is used for the protection,

control and monitoring of overhead lines and cables in solidly,

impedance earthed or isolated networks. The IED can be used

up to the high voltage levels. It is suitable for the protection of

protection of power lines with high sensitivity and low

requirement on remote end communication. The six zones have

fully independent measuring and setting which gives high

flexibility for all types of lines. Load encroachment and adaptive

reach compensation are included.

The modern technical solution offers fast operating time of

typically less than one cycle.

The IED also includes an alternative for use on impedance

earthed or isolated networks. It includes phase preference logic

to select and trip only one line at cross-country faults.

High set instantaneous phase and earth overcurrent, four step

directional or non-directional delayed phase and earth

overcurrent, sensitive earth fault for not direct earthed systems,

thermal overload and two step under and overvoltage

protection are examples of the available functions allowing the

user to fulfill any application requirement.

The distance phase and earth fault protection, and the

directional earth overcurrent protection can communicate with

remote end in any teleprotection communication scheme. With

the included remote communication, following the IEEE C37.94

up control.

Out of Step function is available to separate power system

sections close to electrical centre at occurring out of step.

The IED can be used in applications with IEC/UCA

61850-9-2LE process bus with up to eight merging units (MU)

depending on other functionality included in the IED. Each MU

has eight analogue channels, normally four currents and four

voltages. Conventional and Merging Unit channels can be

mixed freely in the application.

Logic is prepared with a graphical tool. The advanced logic

capability allows special applications such as automatic

opening of disconnectors in multi-breaker arrangements,

closing of breaker rings, load transfer logics and so on. The

IEDs. Basically it means that all binary inputs and outputs on the

IED I/O modules (BOM, BIM, IOM & SOM) can be forced to

arbitrary values.

Central Account Management is an authentication

infrastructure that offers a secure solution for enforcing access

control to IEDs and other systems within a substation. This

incorporates management of user accounts, roles and

certificates and the distribution of such, a procedure completely

transparent to the user.

Flexible Product Naming allows the customer to use an IED-

Communication via optical connections ensures immunity

against disturbances.

Four packages have been defined for the following

applications:

• Single breaker, 1/3 phase tripping, isolated or high

impedance earthed systems (A41)

• Single breaker, 1/3 phase tripping (A42)

• Multi breaker, 1/3 phase tripping (B42)

• Single breaker, 1/3 phase tripping, with PMU (D42)

Figure 6. The multi breaker packages for single- and three phase tripping typical arrangement for one protection sub-system is shown here.

The basic delivery includes one binary input module and one

binary output module, which is sufficient for the default

configured IO to trip and close circuit breaker. All IEDs can be

reconfigured with the help of the application configuration tool

in PCM600. The IED can be adapted to special applications and

special logic can be developed, such as logic for automatic
