Network protection relays

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.

Make everyday operations easier with digital tools

The Easergy P5’s industry leading protection features are complemented by a comprehensive set of tools available on mobile devices such as smartphones or tablets, and desktop computers. This means you get simpler installation, conﬁguration, and maintenance, enabling you to save time and money. Nearby control and monitoring allows users to fully operate the device via wireless communication, from a safer distance.

Digital tools for the Easergy P5 include:

EcoStruxure Power Build – Medium Voltage online ordering tool enables quicker and easier ordering eSetup Easergy Pro software with virtual injection testing

Embedded web server, allowing easy and fast setting changes from a web browser

EcoStruxure™ Power Device app for simpler and safer operation and maintenance mySchneider app, a simple way to access support and product data by ﬂashing the QR code

on the device

As an EcoStruxure-ready solution, the Easergy P5’s digital beneﬁts can be taken even further with best-in-class monitoring of substation equipment health. For example, when paired with EcoStruxure Asset Advisor, users get data for predictive maintenance, which helps them reduce OpEx, speed up processes, and boost efﬁciency.

The arc-ﬂash sensor for zone 3.2 is connected to Device 2 and operates the same way.

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.

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.

Functions Settings

Motor speed setting range 10 – 160% Ωn

Deﬁnite time delay 1 s to 300 s

Motor underspeed - ANSI 14

Functions and description

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.

Functions Settings

Motor speed setting range 10 – 100% Ωn

Deﬁnite time delay 1 s to 300 s

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.

Functions Settings

Rotor stop detection mode Zero speed, Zero speed switch, Motor stopped

Deﬁnite time delay 1 s to 7 200 s

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.

Neutral admittance - ANSI 21YN

The neutral admittance protection function can be applied in high resistance earthed, unearthed or compensated power systems to detect earth fault with increased sensitivity. The neutral admittance Yn is calculated based on the zero-sequence current I0 and the zero-sequence voltage U0.

• Two independent stages with deﬁnite time delay.
