Network Management Solutions We provide mission-critical solutions to manage electrical transmission and distribution grids, including telecoms and energy trading management. Key Benefits Cost-effective, flexible protection and control for medium voltage motors Field-proven algorithms and reliable protection to avoid unwanted trips or under-protection Ease of integration and standardization with universal CT inputs and multiple case sizes Time stamped event reports and waveform capture, simplifying post-event analysis Powerful security and hierarchical password control for centralized management Advanced power system and alxtom diagnostics Application flexibility with user programmable motor overload curve, comprehensive start sequence and re-acceleration scheme Drawout design simplifies testing, commissioning and maintenance for increased process uptime Redundant communications with multiple ports and protocols allowing seamless integration with SCADA and DCS systems Ease of use with intuitive device configuration software and user-friendly logic configuration tool.

To measure the distance and apparent resistance of a fault, the following equation is solved on the loop with a fault: The P24xM series delivers reliable protection for pumps, conveyors, fans, and compressors to ensure maximum process uptime.

Enter or clear Pressing will result in the new settings being adopted, pressing will cause the relay to discard the newly entered values. This chapter includes a description of common power system applications of the relay, calculation of suitable settings, some typical worked examples, and how to apply the settings to the relay. It is possible to manually reset the password protection to the default level by moving to the Password menu cell in the System data column and pressing the clear key instead of entering a password.

When a common signalling channel is employed, the distance and DEF must share alstoom common scheme. The execution of the PSL akstom is event driven; the logic is processed whenever any of its inputs change, for example as a result of a change in one of the digital input signals or a trip output from a protection element.

The DFT used in this way extracts the power frequency fundamental component from the signal and produces the magnitude and phase angle of the fundamental in rectangular component format. All of the relay settings are stored in a database within the relay which provides direct compatibility with Courier communications.

If there is unlocked access to the rear alstm the equipment, care should be taken by all personnel to avoid electric shock or energy hazards. To do this, when all required changes have been entered, return to the column heading level and press the key.

In addition, the primary star point of the VT must be earthed. Residual power generated by the fault The following chart shows slstom adjustment menu for the zero-sequence residual overcurrent protection, the adjustment ranges and the default in-factory adjustments. The settings are arranged so that each column contains related settings, for example all of the p4442 recorder settings are contained within the same column.

With Kbus or ModBus comms, the relay attempts to limit the demands on memory space by saving the analogue data in compressed format whenever possible.

For all other interfaces i. Figure 3 section 0 – The unblocking function if enabled, carries out a function similar to Carrier receive logic. It will be extinguished if the relays self-test facilities indicate that there is an error with the relays hardware or software. The recording time is user selectable up to a maximum of 10 seconds. The protocol provided by the relay is indicated in the relay menu in the Communications column.

This numeric index is used to select a signal for the commissioning monitor port. Sums on one-phase and two-phase loops are performed. Underground cables are vulnerable to mechanical damage, such as disturbance by construction work or ground subsidence.

Alternatively, zone 1 can have an optional time delay of 0 to 10s. This setting should be set equal to the phase angle of the negative sequence current with respect to the inverted negative sequence voltage – V2in order to be at the centre of the directional characteristic.

Application aalstom overhead lines, underground cables, busbars, breakers, transformers, reactors and distributed generation is supported, right from distribution as primary protection to transmission voltage levels as back-up. Move down the Communications column from the column heading to the first cell down which indicates the communication protocol: Inputs to Trigger ITT exceed the number of inputs.

Redo the previously undone action. Thus, backup protection is an important feature of any protection scheme. It should also be verified that the remote source is not sufficiently strong to cause element pickup for a close-up reverse fault.

The fully programmable nature of relays make them an extremely versatile and cost effective solution for all switchgear applications with varied protection requirements.

Using the side flanges of the transparent cover, pull the bottom edge away from the relay front panel until it is clear of the seal tab. Time delays should be sufficient to override any transient dips in frequency, as well as to provide time for the frequency controls in the system to respond. The operating system is also responsible in part for controlling the communication between the software tasks through the use of operating system messages.

All power supply voltages including the 0V earth line are distributed around the relay via the way ribbon cable. Any device that is interested in the information subscribes i. The password is confirmed by pressing the enter key. If the load shedding stage is too small compared to the prevailing generation deficiency, then the improvement in frequency may be non-existent.
