INTRODUCTION

The TTC-1000, 3 Probe Transformer Temperature Controller is a mission
specific programmable controller that measures up to three different probe
temperatures and one calculated winding temperature. The user can program
four (4) or six (6) independent hardware outputs based on the state of pre-
programmed temperature set points, time set points, load set points or the
outputs themselves. The controller can measure any of the three probes to an
accuracy of ± 1 ºC and does not require calibration. Calculated winding
temperature is based on the methods of ANSI C57.91 and uses measured top oil
temperature and load current.
The outputs can be used to:
 Control cooling fans and pumps.
 Provide high temperature, LTC condition, and cooling system performance
alarms.
 Provide a trip output.
 Send temperature, load and status to a master via DNP3.0 or MODBUS
The TTC-1000 is substation hardened and designed to operate over a wide
temperature range of –50 to 85 ºC suitable for installation in outdoor cabinets.
The TTC-1000 contains many features including:
 Measures temperature from -35 to 160 ºC.
 Does not require calibration.
 Up to three optional 0-1 or 4 - 20 mA analog outputs.
 Up to three temperature probes.
 Optional aux CT input for calculated winding temperatures.
 Patented Load Pickup Cooling™ set points for early activation of cooling
based on sudden increases in load.
 Comprehensive Patented Dual Algorithm LTC Condition Monitoring™ for the
detection of both slowly and quickly evolving problems.
 Universal probe kit includes thermo well fitting adapters and probe sleeves.
 Optional magnetic mount temperature probe (for when a thermo well is not
available).
 Reports Min and Max Temperatures, time stamped with date and time.
