Since 1886, when Mr A.C Reyrolle established a small work shop in London, the Reyrolle brand has been prominent at all stages of the power supply chain from generation to large end-users. We design and manufacture relays for the world wide protection and control market. We are committed to high technology development and manufacture with full use of the latest software at all stages of product development, manufacture and testing. This can be seen in the latest digital products that Reyrolle offer. With over 100 years of proven innovative technology and many industry firsts, we are very...

Devices and Fields of Application 1.1.1.1 7SR10 Non-Directional Overcurrent Protection Relay 81 THD Total Harmonic Distortion Supervision Control 79 Auto Reclose Features Cold Load Settings Two Settings Groups Password Protection - 2 levels User Programmable Logic Self Monitoring Circuit Breaker Trip and Maintenance Counter Trip Timers The 7SR10 overcurrent and earth fault relay is developed by using the latest generation of hardware technology and is available in multiple variants depending on power supply, Binary input/binary output configuration and data communication facility. 7SR10 is...

Fault Records Waveform Records Measurands Commands Time Synchronism Viewing and Changing Settings 49 Thermal Overload The thermal algorithm calculates the thermal states from the measured currents and can be applied to lines, cables and transformers. Alarm outputs are given for thermal overload and thermal capacity. Application The 7SR10 overcurrent and earth fault relay is a numerical overcurrent protection relay intended for use in the distribution and industrial networks. It provides a highly comprehensive functional software package with a range of integral application functions aimed...

74T/CCS Trip and Close Circuit Supervision The trip or close circuit(s) can be monitored via binary inputs. Trip circuit failure raises an HMI alarm and output(s). 81HBL2 Inrush Restraint Where second harmonic current is detected (i.e. during transformer energisation) user selectable elements can be blocked and an alarm given. 81THD Total Harmonic Distortion Supervision Total harmonic distortion is the percentage of harmonics present in fundamental frequency current. THD calculates the 2nd to 15th harmonic currents presents inline current and displayed in the ‘Harmonic Meter’ window as a...

The function provides independent phase fault and earth fault/sensitive earth fault sequences of up to 5 trip i.e. 4 reclose attempts before lockout. An auto-reclose sequence can be user set to be initiated from internal protection operation or via binary input from an external protection. Data Acquisition Via Communication Interface RS485 Screened twisted pair Rear terminals RS485 Screened twisted pair Ext Wire loop to Include line terminating Res Rear terminals Fig 4. Typical RS485 connection Sequence of Event Records Up to 1000 events are stored and time tagged to 1 ms resolution. Fault...

User Interface Technical Data Fig 5. User Interface The operator interface is designed to provide a user friendly method of controlling, viewing menus, entering settings, and retrieving data from the relay. Five buttons are provided for navigation around the menu structure. Two dedicated push buttons are provided on the HMI to execute the CB manual close and open operations. LCD A 4 line by 20 character liquid crystal display with power save operation indicates the relay identifier, settings, instrumentation, fault data and control commands. Up to 6 user programmable general alarms can be...
