Universal Relays P3U10, P3U20 and P3U30

2. Product introduction

2. Product introduction

2.1. Warranty

This product has a standard warranty of 10 years.

2.2. Product overview

The relay communicates with other systems using common protocols, such as the Modbus RTU, ModbusTCP, IEC 60870-5-103, IEC 60870-5-101, IEC 61850, SPA bus, and DNP 3.0.

User interface

The relay can be controlled in three ways:

•Locally with the push-buttons on the relay front panel

•Locally using a PC connected to the USB port on the front

•Via remote control over the optional remote control port on the relay rear panel.

Easergy P3U10, P3U20 and P3U30 include all the essential protection functions needed to protect feeders and motors in distribution networks of utilities, industry and power plants for all level of voltage below 132 kV. Further, the relay includes several programmable functions, such as trip circuit supervision and circuit breaker protection and communication protocols for various protection and communication situations.

Protection functions

•Universal, adaptive protection functions for user-configurable applications like feeder, motor and voltage protection from basic non-directional to directional overcurrent protection, thermal overload, and auto-recloser

•Neutral overvoltage, overvoltage and frequency protection including synchronism check for two breakers

•Single-line diagram, measurements and alarms in the user-machine interface (UMI)

•User-configurable interlocking for primary object control

•Optional arc flash detection utilizing point sensors and a fiber loop that can provide system wide arc flash detection.

Virtual injection

•Current and voltage injection by manipulating the database of the product by setting tool disturbance recorder file playback through the product's database

Robust hardware

•User-selectable Ethernet, RS485 or RS232 -based communication interfaces

•Designed for demanding industrial conditions with conformal-coated printed circuit boards

•Standard USB connection (type B) for Easergy P3 setting software

2. Product introduction

Universal Relays P3U10, P3U20 and P3U30

Common technology for cost efficiency

•Powerful CPU supporting IEC 61850

•Thanks to four setting groups, adaptation to various protection schemes is convenient

User-machine interface (UMI)

•Clear LCD display for alarms and events

•Single-line diagram mimic with control, indication and live measurements

•Programmable function keys and LEDs

•Circuit breaker ON/OFF control

•Common firmware platform with other Easergy P3 range protection relays

NOTE: If the device has been powered off for more than about one week, the UMI language after starting is IEC but after about two minutes, it is automatically updated to ANSI.

2.3.Product selection guide

The selection guide provides information on the Easergy P3 platform to aid in the relay selection. It suggests Easergy P3 types suitable for your protection requirements, based on your application characteristics. The most typical applications are presented along with the associated Easergy P3 type.

2.4.4. Password management

NOTICE

CYBERSECURITY HAZARD

To improve cybersecurity:

•Change all passwords from their default values when taking the protection device into use.

•Change all passwords regularly.

Failure to follow these instructions can increase the risk of unauthorized access.

You can change the password for the operator or configurator user accounts in the General > Device info setting view in Easergy Pro.

The password can contain letters, digits or any other UTF-8 characters (total 1–32 characters). However, the new password cannot be any of the default passwords (digits 0–4 or 9999).

NOTE: To log on via the front panel, you need a password that consists of digits only.

2.4.5. Changing passwords for administrator and configurator accounts via PuTTY

Change the password for the administrator and configurator user accounts to reach an optimal cybersecurity level. To log on as the administrator user, you need to use either a serial terminal software or a Telnet client software. This instruction describes how to change the passwords using PuTTY which is freely available at https://www.putty.org/.

1.Download and install PuTTY.

2.Connect the Easergy P3 device to your PC via the USB port in the device's front panel.

3.Find the COM port number for the device (for example, with Easergy Pro).

4.Connect to the device’s COM port via PuTTY.

a.Open PuTTY.

The PuTTY Configuration dialog box opens.
