2. Agenda
2
 About Me
 Purdue University EE
 Overview of selected activities
 Reconciliation of DCS & SIS cabinet IO
 Thermowell study
 Wrap Up

3.  Programmed Motor Protection Relays in BU-521 (Propak)
 This Relay monitors the performance of the motor control starter,
determines if it goes outside acceptable parameters, and trips it
 Wrote a procedure for the relays, which is now in the validation process
 Worked with Rockwell and Eaton
 Work with my supervisor on the instrument air compressor to troubleshoot
the problems using special equipment such as the Fluke 1736 Power Logger ,
and read and learn about this device
 Assisted in use of the Fluke 1736 as it was used to measure voltage and
current of the 3 phases at the same time when energized and tracks it
 The electrical contactor needed to be replaced

Overview

4.  Cataloged the DCS and SIS cabinets: these are the control systems that run the plant and
keep it safe
 Loop sheet is a drafted drawing of the IO module, which show how
the plant was originally designed and modified over time
 DOC 4000 is a recently added software utility that surveys the control
systems to tell what channels are used
 A third resource is the actual field termination strip in the IO cabinet

8. Area 100, 239 spares
Area 200, 168 spares
Area 300, 202 spares
Area 500, 115 spares
Area 900, 100 spares
Over 400+ IO modules in the plant checked as well as terminal strips
Hire a contractor to update and redline loopsheets due to high
percentage of inconsistencies found when comparing loopsheets with
the field and DOC4000

Findings & Recommendations

9.  A thermowell is made for holding a temperature element within the pipe; it is
exposed to the process flow and has to withstand process conditions
 Calculate whether a thermowell needs to be replaced, or passes per the most
recent standards
 Many Dimensional and Process data are input to thermowell design
calculation
9
Thermowell Study

10.  New ASME PTC 19.3 standard (2010) requires more conservative design
 Why are we doing this study? To confirm the thermowells meet new
standard
 Process data for some wells needs to be collected to perform further
calculations, but so far those completed look good

Findings & Recommendations
outside the pipe inside the pipe
typical break point

11. What I enjoyed
 “if your not learning something new everyday your doing
something wrong” John Brubaker
What I didn’t enjoy
 The 3 hours round trip drive which has been some days up
to 5 hrs
Suggestions
 Improve set up with designated engineer and technician as
a mentors
Fall
 Back to school at Purdue
Wrap Up
