Network protection relays
www.se.com/easergy
Note: Electrical power systems are dangerous, protection relays are defined and governed by international standards such as IEC 60255 “Measuring relays and protective equipment” and IEEE C37.97 “Protective relay applications to power systems buses”. Never attempt to install or operate protection relays or associated equipment without the necessary qualifications, training and tools. Exposure to electrical arc-flash incidents can be life threatening, no situation can ever be deemed fully safe. Standards such as NFPA 70E define important risk categorization and such standards identify both distance from, and energy of the arc incident to be important factors. In order to reduce the risk category and improve safety during arc-flash incidents, functionality is available in Easergy P5 protection relays to: i) to operate electrical panel from a safer distance via wireless communication, and ii) arcflash protection functionality to detect and limit the arc energy by tripping the connected circuit breaker faster than in a conventional protection scheme.

Enjoy a package of sought-after features in one device
The Easergy P5 presents a major step forward for protection relays, bringing a number of best-in-class features together in one device.
Built-in arc-flash protection functions
Arc-flashes will always exist when switching or during unexpected conditions. The protection function detects if an arc-flash exists, and take action within milliseconds to isolate the connected circuit breaker, meaning that
arc-flash energy should not grow and cause unexpected outages or risks.
Advanced cybersecurity
IEC 62443 compliant, the Easergy P5 has been designed with an optional cybersecurity package. This means reduced exposure to cyber threats and improved operational security. By default, the Easergy P5 includes important features such as password management, port hardening, and secured communication compliant to the latest international standards.
Intuitive withdrawable design
With a handle built in as part of the design, the P5 can be quickly disconnected or exchanged to speed up maintenance. Wiring, data, communication, and settings (including backup) can be stored with the panel and will be there when the relay is reconnected.
Improved recovery time
When maintenance or testing is required, Easergy P5 helps dramatically decrease your outage recovery time. The backup memory can automatically restore settings, you can continue your operations in as little as 10 minutes.*
*Result of mean time to repair (MTTR) calculation conducted by Schneider Electric
Greater connectivity
The protection relay features seven communication protocols. This includes compliance with IEC 61850 Edition 1 and Edition 2, Modbus (serial/TCP), IEC 60870-5-103, IEC 60870-5-101, Ethernet/IP, and DNP3 (serial/TCP). Easergy P5 can support up to 3 Ethernet protocols simultaneously, including offering dual redundancy with PRP/HSR and RSTP protocols. Moreover, all communication modules can be added at any time, including on-site, during the product life cycle to allow you to upgrade your device in line with future network evolutions.

In this application example, the arc-flash sensor for zone 3.1 is connected to Device 1. If the arc-flash sensor detects light
and simultaneously Device 3 detects and sends an overcurrent condition, the zone 3.1 is isolated by the outgoing feeder breaker.
The arc-flash sensor for zone 3.2 is connected to Device 2 and operates the same way.
The arc-flash sensors for zone 2 are connected to Device 1, 2, or 3. If a sensor detects a flash in zone 3, the light-only signal is transferred to Device 3, which then trips the main circuit breaker.
An eventual arc-flash fault in zone 1 does not necessarily activate the current element in Device 3. However, arc-flash detection can be achieved by using the light-only principle. If an arc-flash occurs in the cable termination of zone 1, an inter-trip signal is sent by Device 3 to the upstream circuit breaker.

Functions and description
Motor overspeed - ANSI 12
The function is based on the direct measurement of motor speed. The overspeed protection function detects racing when the motor is driven by the load, or a loss of synchronization for synchronous motors, or for process monitoring. This function picks up if the speed measured exceeds the speed setting and it will trip after a definite time delay.
•Two stages of overspeed protection with definite time delay
•The function is available when a 12 DI / 4 DO board is present and the motor speed detection function is enabled.

Motor speed setting range |

Definite time delay |

|
|
Motor underspeed - ANSI 14
The function is based on the direct measurement of motor speed. The underspeed protection function can detect the slow-down of motor speed after motor starting, possibly resulting from mechanical overloads or locked rotor. This protection is active after the motor speed has successfully achieved the speed setting. The function picks up if the speed measured drops below the speed setting after having first exceeded the set point by 5%. Under-speed protection is blocked when the motor speed drops below 5% of rated motor speed to avoid unwanted tripping when the motor is switched off.
•Two stages of underspeed protection with definite time delay
•The function is available when a 12 DI / 4 DO board is present and the motor speed detection function is enabled.

Motor anti-backspin (ABS)
For a motor with high inertia, once the CB/Contactor supplying power to the motor is switched off, the rotor may continue to turn for a considerable length of time. In that case, the motor terminal voltage is out of phase and the motor re-starting operation may result in catastrophic failure. In some other applications for example when a motor is on a down-hole pump, after the motor stops, the liquid may fall back down the pipe and spin the rotor backwards. It would be very undesirable to start the motor at this time. In these circumstances the anti-backspin function is used to detect when the rotor has completely stopped, to allow re-starting of the motor.
•One stage of anti-backspin protection with definite time delay
•This function is availaible when Motor Status function is enabled
•3 different criteria for rotor stop detection
•Depending on criteria selected, a 12 DI / 4 DO board and the motor speed detection function may be required.

Fault locator - ANSI 21FL
The function can be used to locate a short-circuit fault and an earth/ground fault in radially operated networks. The fault location is given as reactance (Ohms) and as distance in kilometers or miles. The fault value can then be exported, for example, with an event to a Distribution Management System (DMS). The system can then locate the fault. If a DMS is not available, the distance to the fault is displayed as kilometers and as a reactance value.

Cold Load Pick-up (CLP)
This function helps avoid unwanted tripping of overcurrent protecton elements (50/51, 50N/51N, 50G/51G and 67) during energisation after long periods of outage. Depending on installation characteristics such operations can generate inrush currents that can exceed the pick-up level of protection. These inrush currents may be caused by:
•Magnetizing currents of power transformers.
•Motor starting currents.
•Simultaneous re-energization of the entire facility load (air conditioning, heating...).
In principle the protection settings should be defined in order to avoid tripping on such inrush currents. However if the settings result in insufficient sensitivity levels or too long delays, the CLP function can be used to temporarily increase or inhibit thresholds after re-energization.
