When the fault record is complete i. This allows the following connection media: Undo the last action.

P442 Numerical Distance Protection Relays

The disturbance recorder is supplied with data by the protection and control task once per cycle. Up to 5 switchgear elements may be switched by the bay control models.

It is not possible to go straight to the default display from within one of the column cells using the auto-repeat facility of the key, as alstkm auto-repeat will stop at the column heading. This section also defines the indexed string setting options for all interfaces.

Pressing again will move straight to the alarm reset prompt where pressing once more will clear all alarms. X, alsto following elements are available: This is to avoid possible shock or damage hazards.

The use of four different residual compensation factor settings is permitted on the relay, as follows: When the alarms have been cleared the yellow alarm LED will extinguish, as will the red trip LED if it was illuminated following a trip. The high-speed algorithms will be started if U OR I is detected on one sample. It follows then, that the residual voltage generated by an earth fault on an insulated system will be the highest possible value 3 x phase-neutral voltageas the zero sequence source impedance is infinite.

Generator Protection Relay p Get Price. The acquisition of samples is controlled by a sampling function which is called by the system services software and takes each set of new samples from the input module and stores them in a two-cycle buffer. For Phase to Ground Faults ex.

The user may choose to directionalise operation alsotm the element, for either forward or reverse fault protection for which a suitable relay characteristic angle may be set. Extensive multi-functions and user-friendly logic This multi-function relay range ensures flexible, reliable integration of protection, control, monitoring and measurements for a wide variety of system applications. However, negative sequence current will be present on both sides of the transformer for any fault condition, irrespective of the transformer configuration.

It is possible to apply a negative phase sequence overcurrent relay to detect the above alsotm.

Agile P, P and P distance protection – Manuals

The technical data in this Safety Section is typical only, see the technical data section of the relevant equipment documentation for data specific to a particular equipment. It is possible to manually reset the password protection to the default level by moving to the Password menu alstim in the System data column and pressing the clear key instead of entering a password.

This can then be configured into either: This element would trip for close-up high current faults, such as those where maintenance earth clamps are inadvertently left in position on line energisation. The current inputs will accept either 1A or 5A nominal current menu and wiring options and the nominal voltage input is V.

To select the required column heading use the and keys. These are known as direct access keys. NCIT connection diagrams are not presented in this chapter.

NRC Engineering & Trading Co., Ltd.

It activates all the new settings together, but only after it has been confirmed that the new settings are to be adopted. See also chapter 1 on the user interface.

The protective conductor earth connection must be low-inductance and as short as possible. This includes errors that have been detected by the platform software itself or error that are detected by either the system services or the protection software function. The MiCOM Agile P14x is an advanced feeder management relay platform with pp442 and earth fault protection, as well as autoreclose and a full suite of protection, control and monitoring functions.

This can be improved by switching off the cycle filter in which case one of the following methods to reduce ac noise should be considered. Its comprehensive range of measurement, control and monitoring features enhance power system diagnostics and fault analysis. Hence, a long time delay is necessary to ensure alstkm with other protective devices.

Note that for the P, P and P relays, zone timers tZ1 to tZ4 are started at the instant of fault detection, which is why they are shown as a parallel process to the distance zones. Are familiar with the installation, commissioning, and operation of the equipment and of the system to which it is being connected; Are able to safely perform switching operations in accordance with accepted safety engineering practices and are authorized to energize and de-energize equipment and to isolate, ground, and label it; Are trained in the care and use of safety apparatus in accordance with safety engineering practices; Are trained alsfom emergency procedures first aid.
