2.1 Features

The P253 is a dedicated motor protection relay desi gned to protect motors in industrial networks and
power plants. It offers essential protection f unct i ons for motors deployed in installations from LV t o M V
voltage levels. The P253 relay performs an important rol e i n m any industrial processes with its
diagnostic features improving asset health monitoring.

The principal protection functions in the relay include thermal overload, negative sequence
overcurrent, loss of load, prolonged start, locke d rot or (starting/normal running), restricted earth fault,
excessive no. of starts and speed switch input for stall rotor detection. Additional versatility is provided
thanks to the inclusion of backup overcurrent and earth fault protection, with up to 3 independent
stages (IEC and IEEE curve types are provided for IDMT f unct i on), breaker fail and trip circuit
supervision functions. Multiple setting groups are included. The hardware capability is broadened by a
sensitive earth fault CT option, and a universal auxiliary power supply range to permit standardisation
in procurement and inventories.

The user can assign any of the logical/physical statuses to binary inputs, binary outputs and
programmable LEDs. This provides flexibility to program the relay as per the application requirements.
All the output contacts are changeover type for ease of i m pl ementing the desired wiring schematic.

The P253 offers supervision functions including measurement, monitoring and recording. The P 253
records the starting current which is very helpful in m onitoring motor performance during the critical
starting period. Industry and utility protocols such as MODBUS, IEC 60870-5-103 and DNP3.0 are
available for transmitting relay data to a supervisory control system via communication networks. The
intuitive operator interface facilitates easy reading of measured values and simple configuration of t he
relay.

2.1 Overview of Hardware Design

The P253 hardware design overview is explained with the help of the schematic diagram. The P253
hardware consists of three sets of internal Current Transformers (CTs). These internal CTs are
designed to cater to protection & metering requirements. Dedicated CT is available for the earth fault
protection requirements. The relay also has provision for the built-in SMPS unit which accepts power
supply input of 24-230 V AC/DC from external source and outputs 12 V and 24 V DC for internal
circuitry. The current signals acquired as analogue inputs get pr ocessed through operational amplifier,
filter circuit, multiplexer, ADC (Analog to digital converter) and finally fed to CPU.

The CPU design is a hybrid of the digital signal process or (DSP) and high speed microcontroller which
runs complex algorithm for deriving the fundamental & harmonic component from the input current
signals. The digital inputs and outputs modules are designed to interface the monitoring, control and
protection signals through optically isolated circuit as per the field requirements. The other peripherals
modules like 16x2 LCD display, feather touch keys, USB and RS485 communication interfaces,
battery backup for RTC and built in memory circuits are int egrated as per the schematic diagram and
enclosed in the IP-52 enclosure.

2.2 Microcontroller with DSP Module

The hardware is designed around 32 bit controller housed in small 100 pin SMD package. It is a high
speed fix point controller having MIPS’s M4K® 32-bit core with 5-stage pipeline capable of operating
up to 80 MHz.This controller is referred to as MCU (Microcontroller unit).

2.2.1 Microcontroller Module (processor board) Features

• 512K Flash memory (plus an additional 12 KB of Boot Flash)

• 128K on chip SRAM memory

• Multiple interrupt vectors with individually programmable priority

• Fail-Safe Clock Monitor mode

• Configurable Watchdog Timer with on-chip Low-Po wer RC oscillator for reliable operation

• Internal 8 MHz and 32 kHz oscillators

• Six UART modules with:

• RS-232, RS-485, USB and LIN support

• Four SPI modules

• Five I2C™ modules

• Hardware Real-Time Clock and Calendar (RTCC)

• Five 16-bit Timers/Counters

2.3 Microcontroller and Analog Measurement

P253 hardware supports 4 analog inputs. The relay hardware uses an external 16 bit ADC converter
with capability to sample 8 signals simultaneously to avoid any phase angle error and achieve higher
accuracy. In P253, only 4 channels of ADC converter are used. This external ADC can measure input
in a range of – 10 V to +10 V. The ADC interface uses a SPI serial interface to avoid any software
delays. The MCU continuously monitors different analog signals like line and E/F currents through
CTs, multiplexer and ADC.

The relay is designed for 5 amp and 1 amp CT secondary cu rr ent signal. These inputs are further
scaled down to low voltage signal by using an internal cur rent and transformer. The internal current
transformer converts nominal current signal to 3.3 mA. These analog signals are then passed through
protection circuit, anti aliasing filter and amplifier which scales analogue signal to required ADC range.
This anti aliasing filter blocks all high frequency components and surges to avoid measurement error.
The sample and hold (S/H) circuit and multiplexer sample all analog signals at same instant to avoid
and phase angle error and give maximum accuracy.

3 Hardware Design

P50 Agile P253253

3-8

P253/EN M/C

The MCU acquires analog values at the rate of 16 sam pl es per cycle. Digital signal processing (DSP)
performs powerful numerical algorithms which converts this signal in to equivalent vectors. Once the
signal is converted into vectors, number of parameters are derived from it such as phase currents (Ia,
Ib, Ic), positive sequence current (I1) and negative sequence current (I2). The MCU also calculates
harmonic contents of the current signals (actual harmonics depend upon type of relay). All
measurements are tuned to fundamental frequency i.e. 50 Hz or 60 Hz, so that the relay will remain

stable during distorted waveform generated by modern electronics load.
The typical frequency response of tuned filter for 50 Hz is shown in figure 4.

V00278

Figure 4: Frequency response of tuned filter for 50 Hz

The measurement is totally immune to all higher harm onics which makes relay operation reliable. All
these measured values are then used for different prot ect i on functions such as over current/Earth
Fault and negative phase sequences. The actual prot ection function depends on type of relay and
described in the rest of the document.

2.4 Digital Input/Output Module

This module supports 6 numbers of Digital input DI and 6 number s of Digital output DO channels for
acquiring filed signals or controlling field devices respectively. The DIs are isolated f rom other circuits
by using Opto isolators. The threshold voltage at which Opt o coupler turns ON is controlled by
comparator based on the voltage range selected duri ng device ordering.

2.5 Power Supply Module

The power supply module is a designed using modern PWM based switching mode technique. It
converts input supply to the 12 V and 24 Vdc low voltage su ppl y for relay electronics and control
circuit. It also provides necessary isolation from input power supply. The normal operating voltage
range is 24 V – 230 VAC/DC.

2.6 Communication Module

The P253 supports 2 numbers of isolated ports for communication.

• (a) USB port provided on front of the relay

• (b) RS 485 (2 wired) port provided on the rear side of relay.

The relay can be accessed using the P50 Agile Configurator. Rear port supports open protocols like
IEC60870-5-103/MODBUS or DNP3.0 (ordering option) and is used for external communication.

2.1.4 RS 485 Port

The RS485 port is provided at the rear of relay (near to terminal block) for permanent SCADA
connectivity. The separate 5 Pin connector is used to avoid accidental connection of power wiring to
communication input. The RS485 port can be used to download Settings, Fault data, Live Event and
Disturbance Records.

2.1.5 USB Port

The USB port is situated on the front panel in the bottom right hand corner, and can be accessed by
opening the flap on the front of the relay. This port is used to communicate with a locally connected
PC.

It has three main purposes:

• Transferring settings information to/from the P C from/to the device.

• Downloading firmware updates.

• Downloading relay data for analysis.

The port is intended for temporary connection during testing, installation and commissioning. It is not
intended to be used for permanent SCADA communicati ons.

You can connect the unit to a PC with a USB cable up to 15 m in l engt h.
The USB port includes a USB full-speed function controller, USB transceiver, oscillator, EEPROM, and

synchronous serial data bus (UART). No other extern al US B components are required.
For configuration/setting the appropriate ‘config port’ has to be selected from the SYSTEM DATA

menu.

2 CONFIGURATION

Each product has different configuration parameter s according to the functions it has been
designed to perform. There is, however, a common m ethodology used across the entire product
to set these parameters.

This chapter describes an overview of this common methodology, as well as providing concise
instructions of how to configure the device.

Using the HMI you can:

• Display and modify settings

• View the digital I/O signal status

• Display measurements

• Display fault records

• Reset fault and alarm indications

The keypad provides full access to the device functionality by means of a range of menu options.
Information is displayed on the LCD.
