 I have attended the EMI/EMC Training session Organized by L&T.
 Attended signal Integrity Training.
HARDWARE TESTING
 Environmental Testing
 Debugging of the Development card
INNOVATIVE IDEAS:
Participated in TECH-PANORAMA Competition, presented innovative ideas and got appreciation
with-in L&T Organization.
Project Experience:
Title of Project : ENVIRONMENTAL MONITORING SYSTEM(EMS)
Project Summary : EMS System monitors the SERVER/INDUSTRY Room , senses
Environment conditions and then sends information to the user.
The information can be passed through WIFI, Ethernet, GSM
communication protocol. It can communicate on LAN , mobile SIM
Operator, internet access etc so that if user is not in local area
Network then also it can get information at remote site . It can also
operate the devices from remote locations.
Role : Design and development of EMS device
Technical contributions : POC(Proof of concept), Schematic design in ORCAD , PCB design in
PADS layout,BOM, Testing of prototype.
Technology Used :
1) High performance ARM cortex M4 32-bit RISC core-- STM32f427
2) Memory Devices used :- SDRAM, NANDFLASH , DATA FLASH,
EEPROM etc
3) GSM, WIFI, RS3232, ETHERNET, RS485(HALF & FULL DUPLEX),
SPI,I2C etc
4) TEMPERATURE SENSOR , HUMIDITY & TEMPERATURE SENSOR,
SMOKE
SENSOR & FIRE SENSOR, PIR SENSOR etc

Title of Project : LOW VOLTAGE CUTT-OFF DEVICE(LVCD)
Project Summary : LVCD Device is actually monitoring the voltage level of battery and
will
automatically turn-off the load connected to the battery if
voltage falls
to below specified limit. One can destroy a lead-Acid battery is
to
discharge it below its manufacturers specified discharge voltage
limit
(depth-of-discharge (DoD)), and leave it at such low voltage for
a few
hours. This situation results from the irreversible hardening of
the
discharge generated lead sulphate (PbSO4) on both the positive
and
negative plates of the battery. To avoid this, all battery usage
systems
should be incorporated with discharge monitor/cut-out
systems
Role : Design and development of LVCD device
Technical contributions : POC(Proof of concept), Schematic design in ORCAD , PCB design in
PADS layout,BOM, Testing of prototype and stabilization of the
device
for different load current.
Title of Project : LOW COST AC to DC CONVERTOR
Project Summary : Purpose of this device is to provide load current upto 150mA at low
cost.
Title of Project : Feeder Protection Relay
Team size : 2
Project Summary
• The project Feeder Protection System provides feeder protection, monitoring and

metering in an integrated, economical, and compact package.
• As part of the Universal Relay (UR) Family, this FPR features high performance
protection, expandable I/O options, integrated monitoring and metering, high-speed
communications
Role : Design Engineer
To design Analog input/output module (AIO) card
• Requirement gathering, Presentation of concepts for the design,
• QFD analysis of critical components selection like CPLD, ADC etc.
• Analysis, simulation of circuits & design as per requirement
• Board level power distribution and power conversion
Project: Three Phase Versa-Tech Re-closer
Team Size: 3
Role : Designing/Testing/Debugging
Client: HUBBELL POWER SYSTEMS
Project Summary
• Three Phase Versa-Tech Re-closer provide Three phase High Voltage Line protection,
Metering, run protection algorithms, detects the faulty condition and issues trip
command to the vacuum interrupter through RF and breaks the power line.
• It has mechanism that can automatically close the breaker after it has been opened
due to a fault.
• If the fault is a permanent fault (downed wires, tree branches lying on the wires, etc.)
the Recloser will exhaust its pre-programmed attempts to re-energize the line and
remain tripped off until manually commanded to try again.
Technology Used :
1) Intelligent MIU by having 32bit high performance DSP Technology
2) 900 MHz RF communication
3) Synchronization with GPS timing
4) Battery SOC monitoring and cell balancing

Project: CAPACITOR MODULE DESIGN.
Team Size: 3
Role: Design engineer
Client: ROCKWELL AUTOMATION
Description:
• Capacitor module is developed for Energy Storage with advanced features for current
protection and Voltage Monitoring circuit.
• 1640uF Capacitance are used in external capacitor module
• The purpose of the Midrange External Capacitor Module is to provide a means of adding extra
bulk capacitance to the DC Bus of the Midrange Drive system.
• It could either be connected to a Midrange Drive in standalone mode, or to a system of drives
connected in a shared DC Bus configuration (shared AC/DC or common bus).
• It monitors DC Voltage with use of DC Bus Sensing Circuit. Signal conditioning block processes
these signals for inputs to ADC of 32-bit TMS320F28030 Controller.
Technical Contribution:
• Requirement gathering and Presentation of Concepts for the Capacitor Module
• Design of signal conditioning circuit & Capacitor Selection.
