KVGC 202 AREVA

KVGC 202 AREVA,Voltage Regulating Control Relay, Ready Stock  !!!

The KVGC202 voltage regulating relay use numerical techniques to derive control functions. Six multiplexed analogue inputs are used, sampled eight times per power frequency cycle. The Fourier derived power frequency component returns the rms value of the measured quantity. To ensure optimum performance, frequency tracking is used. The channel that is tracked is chosen, in order, from Vbc (low accuracy), external TPI supply and IL. Eight output relays can be programmed to respond to any of the control functions and eight logic inputs can be allocated to control functions. The logic inputs are filtered to ensure that induced ac current in the external wiring to these inputs does not cause an incorrect response. Software masks further enable the user to customise the product for their own particular applications. They select/interconnect the various control elements and replace the interconnections that were previously used between the cases of relays that provided discrete control functions. An option is provided to allow testing of the output relays via the menu structure. The relay is powered from either a dc, or an ac, auxiliary which is transformed by a wide ranging dc/dc converter within the relay. This provides the electronic circuits with regulated and galvanically isolated supply rails. The power supply also provides a regulated and isolated field voltage to energise the logic inputs. An interface on the front of the relay allows the user to navigate through the menu to access data, change settings and reset flags etc. As an alternative the relay can be connected to a computer via the serial communication port and the menu accessed on-line. This provides a more friendly and intuitive method of setting the relay, as it allows a whole column of data to be displayed at one time instead of just a single menu cell. Computer programs are also available that enable setting files to be generated off-line and these files can then be down loaded to the relay via the serial communication port. In addition to control functions the relay can display all the values that are measured and many additional ones that are calculated. Useful time stamped data for post event analysis is stored in event records. This data is available via a serial communication port for access locally and/or remotely, with a computer. Remote control actions can also be made and to this end K Range relays have been integrated into SCADA systems. KVGC202 relay provide the user with the flexibility to customise the relay for their particular applications. They provide many additional features that would be expensive to produce on an individual basis and when the low installation costs are taken into account it will be seen to provide an economic solution for tap change control.

KAVR 130 ALSTOM

KAVR 130 ALSTOM - Ready Stock !!

KAVR Series
Compact, Multi-shot Auto-reclose Relay

It is a compact and simple solution for single or 3-phase reclosing as the first shot. Applicable to all power systems, these relays are user-friendly and enhanced with flexible operating logic.

End of life notice: The KAVR has been discontinued as from June 30th, 2016

Single or 3-phase auto-reclosing capacity

KAVR is a multi-shot auto-reclose relay with integral check synchronising for application to feeders switched by a single circuit breaker. Part of the K relay range, it can be integrated into an overall protection and control system via its integral serial communications facility.

The KAVR 130 can be applied for single or 3-phase reclosing, while the KAVR 100 is only for three-phase reclosing. Appropriate for all power systems from distribution to transmission voltages, KAVR relays can be simply configured for both automatic reclosing and manual reclosing interlock.

User-friendly, compact and flexible

Compact, numeric KAVR relays benefit from optimal design. They are equipped with a user-friendly interface and flexible operating logic.

Introduction
The K Range of overcurrent relaysprovides comprehensive protectionfor phase and earth faults, togetherwith measurements,communications, control andrecording facilities.Within the range, the KCGG relaysprovide non-directional overcurrentand earth fault protection, while theKCEG and KCEU relays allow eachstage of protection to be selectivelydirectionalised.The relays in the range aredesigned to operate with a widerange of ac or dc auxiliary powersupplies. If a secure supply is notavailable, the KCEG 242 andKCEU 242 models can be poweredfrom either an auxiliary supply (acor dc) or from the CT circuit. Thus inthe event of auxiliary supply failure,tripping functions will remainoperational.
