It should alsyom be verified that the remote source is not sufficiently strong to cause element pickup for a close-up reverse fault. Related Products View All. This is vital to prevent unnecessary interruption of the supply resulting from inadvertent operation of this element. Sustained underfrequency has implications on the stability of the system, whereby any subsequent disturbance may lead to damage to frequency sensitive equipment and even blackouts, if the underfrequency condition is not corrected sufficiently fast.

These four elements are not distinguishable to the user, and are all processed by the same alshom board.

To use the rear port with IEC communication, the relays communication settings must be configured. Note that the timer hold aostom should not be used where high speed autoreclose with short dead times are set.

Substation Automation Solutions Alstom Grid Automation provides utilities and industry with the mission critical software systems and equipment needed to manage the flow of electricity in transmission and distribution grids, ensure grid stability and to protect and control substations. Reset of fault and alarm conditions. See also in 4.

The equipment documentation should be consulted before installing, commissioning, or servicing the equipment. The Blocked Zones function links are set to 1 to block zone tripping, or set to 0 to allow tripping as normal.

Micom P442 Numerical Distance Protection Relays

Using advanced numerical technology, MiCOM relays include devices designed for application to a wide range of power system plant such as motors, generators, feeders, overhead lines and cables. Out of service Yellow indicates that the relays protection is unavailable. The three options are shown in table 1 below. Enter Your Email ID. Voltage transformer supervision VTS. Published on Dec View 1. The protection and control software resumes execution when the number of unprocessed samples in the buffer reaches a certain number.


The relay should also not trip during loss of stability since there may be a utility strategy for controlled system break up during such an event. In addition, the MiCOM Agile P provides a wide range of measurement, monitoring, post fault analysis and self-diagnostic features.

The database of settings and measurements must be accessible from all of the relays user interfaces to allow read and modify operations. Alston new message is re-transmitted at user-configurable intervals until the maximum interval is reached, in order to overcome possible corruption due to interference, and collisions.

The equipment should be disposed of in a safe manner.

To use the rear port with Modbus communication, the relays communication settings must be configured. For the P distance protection relay, the protection task is executed twice per cycle, i.

Undo the last action. PSL features 7. There is alwtom fixed upper limit to the number of links in a scheme. This is done by detecting changes in the analogue input signals and compressing the recording of the waveform when it is in a steady-state condition.

However, typical settings for the element are as follows: They also provide an additional voltage input for the check sync function. Connections that are pre-wired, but not used, should preferably be grounded when binary inputs and output relays alsstom isolated.

RP2 Protocol Courier The next cell down indicates the status of the hardware, e. Read access to measurements 2. This includes all the relay aostom and measurements.


The majority of faults on overhead lines are transient or semi-permanent in nature, and multi-shot autoreclose cycles are commonly used in conjunction with instantaneous tripping elements to increase system availability.

Alatom the menu selected default display will be restored following the menu time-out elapsing. Modbus address 23 Up to 32 relays can be connected to one Modbus spur, lastom therefore it is necessary for each relay to have a unique address so that messages from the master control station are accepted by one relay only. The second stage includes IDMT curves.

Various warning messages may be displayed as a result of these checks. The default settings will initially be placed in the scratchpad and will only be used by the relay after they have been confirmed. Insertion and withdrawal of extender cards Extender pp442 are available for some equipment. This allows the following connection media: Instantaneous and time delayed neutral overcurrent protection.

Alternatively, the element may be set as non-directional.

P Areva Distance Relay

Industrial plants that are dependent on utilities to supply part of their loads will experience underfrequency conditions when the incoming lines are lost. This can be done as previously using the front port serial connection of the relay, or now optionally over the Ethernet connection if preferred.

Circuit breaker failure protection – Generally set to backtrip upstream circuit breakers, should the circuit breaker at the protected terminal fail p42 trip. All measurands are presented using the measurement Logical Nodes, in the Measurements Logical Device. This technique is employed to provide extra security, and so that several setting changes that are made within a group of protection settings will all take effect at the same time.
