LumaSMART®User Manual Introduction •13
2Introduction
This chapter introduces the LumaSMART®system and describes the system’s technology along with the major
features and benefits.
2.1 System Overview
LumaSMART is a fiber optic temperature sensing and control system specifically designed for direct winding
temperature measurement and cooling control in high-voltage power transformers. Building on years of successful
field-proven performance of the industry-standard
LumaSense WTS-22 and ThermAsset systems, the LumaSMART system incorporates new features that improve
ease of use, add capability, and reduce the cost of ownership.
LumaSMART System Overview
The LumaSMART controller provides direct measurement of the transformer winding temperature with high
accuracy and real-time response. Programmable temperature alarm setpoints and relays are available to directly
control transformer backup cooling equipment.
Note: Setpoint is defined as a temperature, or function of multiple temperature readings, at which
an alarm or relay is energized or deenergized.
Analog outputs and a digital serial interface are available to communicate with Supervisory Control and Data
Acquisition (SCADA) and other data-logging systems. Modbus, DNP3, and IEC61850 are also supported.

LumaSMART®User Manual Introduction •14
2.1.1 System Organization
The figure below shows the LumaSMART controller organization. The optical components, microprocessor, and a
Digital Signal Processor (DSP) are contained in the Fiber Optic Thermometer (FOT) module, which sends output
(temperature data and several status signals) to the CPU and sets analog output levels. The CPU then displays data
on the LCD display, controls the relay outputs, and sends the data through the communication ports.
LumaSMART Controller Organization
2.2 Theory of Operation
LumaSMART uses LumaSense Technologies’ patented Fluoroptic®technology, which is based on a temperature-
sensitive phosphorescent sensor attached to the end of an optical fiber. Pulses of light transmitted down the fiber
optic probe excite the sensor and causes it to phosphoresce. The
Digital-Signal-Processor (DSP)-based electronics detect and calculate the decay time of this phosphorescence after
each pulse. This decay time varies precisely with the sensor temperature, providing the basis for accurate
temperature measurement. The LumaSMART controller achieves ± 2.0 °C when using the LumaSense DipTip
RuggedProbe and QualityProbe sensors.
2.2.1 Temperature Sensor
LumaSMART temperature measurement is based on the phosphorescence decay time of a special phosphor
sensor, located at the end of a fiber optic cable. This specific sensor is basic to the LumaSMART function. The figure
below illustrates temperature sensor construction.
Probe Design
Light generated by an excitation LED is routed through a probe extension and connectors, where it falls on the
phosphor material at the probe tip. When stimulated with red light, the phosphor emits radiation over a broad

LumaSMART®User Manual Introduction •15
spectrum in the near infrared region. The time required for the phosphorescence to decay is dependent upon the
phosphor temperature.
After the LED is turned off, the decaying phosphorescent signal continues to transmit through the fiber to the
instrument, where it is focused onto a detector. After the LED is turned off, the return signal is amplified and
sampled. The measured decay time is then converted to temperature, using the built-in DSP.
2.2.2 Extracting Temperature from Phosphorescent Decay Time
The figure below illustrates the method used to extract the phosphor sensor phosphorescent decay time constant
(). A mathematical curve fit correlates individual data points with stored values of (). The measured value of ()
is then conditioned using the values in an internal calibration table to determine temperature.
Plot Representation of Method for Extracting Decay Time
2.3 System Components
2.3.1 LumaSMART®Controller
LumaSMART’s flexible design enables sophisticated temperature control of the transformer without the need for
additional instruments. One of the primary design features of the LumaSMART controller is reliability. The system
utilizes all solid-state light sources, an LCD display, and a touch screen designed to withstand years of use. In
addition, the controller can be wall or panel mounted or in a NEMA 4X enclosure.

LumaSMART®User Manual Introduction •16
Internal Components
Access to the inside of the LumaSMART controller is rarely needed since all connections to the LumaSMART
controller are made along the exterior surface.
LumaSMART Controller Internal Components (Front Facing Upwards)
Display
The LCD is a VGA TFT display with integrated touch panel which allows both data display and data entry. The
display has an LED backlight with user programmable intensity and time to wait before it dims.
SBC and Comm Board
The SBC is an industrial Windows Embedded PC in a PC104+ form factor. The COMM Boards is a PC104 board that
adds four RS232c ports to the SBC.
Power Supply
The power supply is a universal input power supply capable of operating from 100 to 240 VAC, 50/60 Hz or 127–
370 VDC.
Fiber Optic Thermometer Module
The fiber optic thermometer modules each contain up to four standard optical ST connectors (channels) that
accept connections from the temperature probes through fiber optic extensions cables. The other ends of the
extension cables are connected to the tank wall penetrator terminals.
FOT Module (Internal Components)

LumaSMART®User Manual Introduction •17
Relay Module
The relay module has eight Form-C relays on its main board. It has the external connectors for the eight relays on a
daughter board.
Relay Module (Internal Components)
Interconnect Board
The interconnect board provides the electrical interconnection between the extra module and the base unit. It also
provides the external connections for power and communications.
Analog Output
The LumaSMART controller has an analog output for each temperature channel on the external connectors for
each FOT module.
Each analog output is associated with a corresponding measurement channel (temperature probes). Analog
outputs are labeled 1 to 16, where Analog Output 1 is associated with Channel 1; Analog Output 2 is associated
with Channel 2, and so forth.
The analog outputs are designed with current drivers that produce a minimum output of 4 mA and maximum
output of 20 mA during normal operation, or alternatively, 0 to 1 mA. During Probe Error and Measurement
generation failure, analog output is a 20 mA.
The analog drivers convert the selected temperature range of each temperature channel to a specified current
range. That is, the analog drivers can be thought of as four blocks with a single input and single output each. The
input of each block is its temperature channel measurement in degrees Celsius (°C) and the output of each block is
a current value (milliamps).
Analog Driver Blocks

LumaSMART®User Manual Introduction •18
All channels convert a -30 to +200 °C temperature range to a 4 to 20 mA current range, where 4 mA corresponds
to -30 °C and 20 mA corresponds to +200 °C.
Analog Driver Output (Temperature versus Current)
Front Features
Under normal operating conditions, the LumaSMART controller case never needs to be opened. The front panel
displays the temperatures being monitored, relay activation status, and system status.
LumaSMART Controller Front View
The figure below illustrates the components accessible from the LumaSMART controller’s front panel. Table 1
describes the function of each front panel component.

The number of connections a user will need to make will depend on the unit’s configuration (See Configuration
Options later on in this section for more information on configuration options).
