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 600mA at low
cost.
Title of Project : Feeder Protection Relay
Duration of Project : Jan-13 to Present
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
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
