Description of Functionality With reference to figure 2 ‘Function Diagrams’. 27/59 Under/Over Voltage Each element has settings for pickup level, drop-off level and Definite Time Lag (DTL) delay. Operates when voltage exceeds setting for the duration of delay. 47 Negative Phase Sequence Voltage Each element has settings for pickup level and Definite Time Lag (DTL) delays. Operates when NPS voltage exceeds setting for the duration of delay. 59N Neutral Overvoltage Neutral overvoltage can be used to detect earth faults in high impedance earthed or isolated systems. Operates when neutral voltage...

Data Acquisition Via Communication Interface Sequence of event records Up to 1000 events are stored and time tagged to 1ms resolution. Fault Records The last 10 fault records are displayed on the relay fascia and are also available through the communication interface, with time and date of trip, measured quantities and type of fault. Waveform recorder The waveform recorder stores analogue data for all poles and the states of protection functions, binary inputs, LEDs and binary outputs with user settable pre & post trigger data. A record can be triggered from protection function, binary input...

Reydisp Evolution Communications Editor To facilitate interfacing to a substation the relay default Protocol configuration may be modified using the communication editor software tool. The communication editor is a PC based software package provided within the Reydisp software suite which allows modification of the IEC60870-5-103, DNP 3.0 and MODBUS Protocols. kJpM. H«*. W~to.

User Interface The relay is housed in a 4U high size E4 or E6 case with a removable clear plastic fascia cover. The plastic fascia cover can be ordered with or without two push buttons to allow the user to view the settings and instruments without removing the cover. Two plastic handles are provided to allow the relay to be withdrawn from its case, contacts in the case ensure that the normally closed contacts remain short circuited when the relay is withdrawn. The rear terminal blocks comprise M4 female terminals for ring crimp wire connections, to provide a secure and reliable termination. Fig.11...
