Page 24 Introduction Front Fascia The fascia Light Emitting Diodes (LEDs) and Liquid Crystal Display (LCD) provide information on the device function and report events, states, and measured values. The fascia keypad enables on-site operation of the device without the need for the Reydisp software tool. Device information such as setting parameters, operating and fault indications or measured values can be displayed, and setting parameters changed.
Page 25 Introduction Binary input and binary output functionality is fully programmable. These can be used for a number purposes. Voltage operated binary inputs allow the device to receive external information from the system or from other devices. The binary output relays are used to initiate primary plant switching and provide indications for remote signaling of important events and states.

Page 28: Introduction
Basic Structure of the Device Functionality 2.1 Introduction Introduction The device includes protection, supervision, control, data communications and real time clock functions. The protection, control and supervision functions that can be included in the device are dependent on the 7SR5 device type and it’s hardware configuration. The functionality available to a user is included in the device Function Template.

Basic Structure of the Device Functionality 2.2 Analogue Inputs Analogue Inputs The device functionality is dependent on the analogue input configuration. Overcurrent devices have 4 CT inputs and directional overcurrent devices have both 4 CT inputs and 4 VT inputs.

Basic Structure of the Device Functionality 2.3 Function Groups and Function Elements Function Groups and Function Elements The default overcurrent application template includes functions that are typically used in this type of device. The appropriate analogue inputs are provided in the 7SR5110 overcurrent/earth fault relay and 7SR5111 direc- tional overcurrent/earth fault relays.

Default RM2 function templates are offered for selection automatically when a new device is created in RM2.

Page 34: Device Startup
Basic Structure of the Device Functionality 2.4 Device Startup Device Startup 7SR5 devices can be started in any 1 of 3 modes: • Auxiliary Power On = Device is switched on by applying the auxiliary supply voltage. • Expected = User initiated start e.g. after a change to the device user configuration or firmware upgrade. •...
Page 35 Basic Structure of the Device Functionality 2.4 Device Startup The device also provides user alerts to provide indication of the devices configuration: • The Device Not Configured message shall flash up on the LCD after a short duration if the user has not changed any parameter in the device.
Page 36: Real Time Clock
Basic Structure of the Device Functionality 2.5 Real Time Clock Real Time Clock In order to allow the correct time recording of events synchronously, devices need a time synchronization. The device clock function is used to time tag the stored data i.e. demand/data logs, waveform records, fault records and event records.
Page 37 Basic Structure of the Device Functionality 2.5 Real Time Clock • Failure to receive a periodic time synch from the backup clock will result in a backup clock lost event/ alarm (if configured). The period before raising the alarm is the user setting Backup Time Sync Lost Delay.
Page 38 Basic Structure of the Device Functionality 2.5 Real Time Clock The device wil interrogate both NTP servers cyclically every minute. It normally synchronizes itself on the first parameterized, the primary NTP server. If the first NTP server doesn't respond to a query twice successively within the 1 minute’s polling interval, the time synchronization switchovers to the secondary, second server.
Page 39 Basic Structure of the Device Functionality 2.5 Real Time Clock [sc_7SR5_TimeZone, 1, --_--] NOTE The offset time zone for time synchronization is with reference to UTC and not the relays local time. NOTE If a time zone for time synchronization is already preset for the communication protocol, for example, DNP3 or IEC 60870-5-103, the time zone of the time source must be identical.

Page 421: 79 Automatic Reclosing
Control Functions 7.3 79 Automatic Reclosing 79 Automatic Reclosing Overview of Functions 7.3.1 The cause of a high proportion of faults on an overhead line (OHL) network is transient in nature. The arc is then sustained by energy supplied from an otherwise healthy power network. These faults can be cleared by any circuit‑breaker trip and the network restored by reclose of the circuit‑breaker after the line has been dead for a short time to allow the fault current arc to fully extinguish.
Page 422 Control Functions 7.3 79 Automatic Reclosing The autoreclose function can provide a number of reclosing attempts (shots). The function has a number of configuration settings which are used for all fault types. The autoreclose sequence is defined by settings for the number of shots and deadtimes for different fault types: phase fault (50, 51), earth fault (50G, 50N, 51G, 51N) or sensitive earth fault (50GS, 51GS) and external fault (via binary input configured as 79 Ext Trip).
Page 423 Control Functions 7.3 79 Automatic Reclosing The menus, allow the user to set independent protection and autoreclose sequences for each type of fault i.e. phase fault (P/F), calculated/measured earth fault, sensitive earth fault or external protections. Each autoreclose sequence can be user set to up to 4-shots i.e.5 trips + 4 reclose sequence, with independ- ently configurable types of Protection Trip.

The relay will go to Lockout on the last HighSet trip. This function can be used to limit the duration and number of high current trips that the circuit‑breaker is required to perform.
Page 430 Control Functions 7.3 79 Automatic Reclosing • Close Inhibit At the end of the deadtime the autoreclose progresses to Close Inhibit. The line and bus voltage levels are checked for close conditions in devices with check syncronizing. DLC/DBC time delays and check sync parameters are applied depending on voltage level and phase and the applicable Check Sync, System Sync or Close on Zero settings.
Page 431 Control Functions 7.3 79 Automatic Reclosing • Lockout This state can be reached following a complete autoreclose sequence where the fault has persisted to the final shot. Typically this is because the protection has operated during the final reclaim time or the circuit‑breaker is open at the end of the final reclaim time.
