Product Literature

The TTC-1000 is an advanced microprocessor based transformer temperature monitor for oil-filled power transformers that contains a full compliment of programmable features. It is suitable for both retrofit and new transformers

Four independent temperature set points per temperature probe with settable pickup and drop out temperatures for hysteresis and under temperature operation

Patented Load Pickup Cooling™ set points for transformer pre-cooling

Up to a total of nine CT inputs for: Up to Three Winding or individual phase winding temperatures and up to six CTs for true three-phase motor monitoring. Split core CT provided

Built-in LTC condition monitoring. Settable time delay on pickup improves sensitivity and reduces false alarms. Also includes rate of rise feature for detecting rapid temperature increases in the LTC tank. Mag mount probe available. Use three probe units for monitoring transforms with two separate LTC tanks

Optional LTC position monitoring assists in diagnosing LTC problems

Built-in fan bank alternate feature

Three independent time set points for fan exercising. Programmable counter enables selection of daily, weekly, or monthly exercising

Programmable scheme logic with up to six programmable form C relay outputs

Dedicated form B Device Alarm Relay with built-in self check

Minimum and maximum temperature display time stamped with date and time

Data logging feature permits recording of time-stamped temperature and load data

Flash memory permits firmware upgrades through a remote PC

Optional DNP3.0 Level 1 or MODBUS RTU Communiations, read all binary and analog outputs nad command cooling remotely. Available with multi-mode fiber interface

Up to four analog outputs programmable to 0 to 1 or 4 to 20 mA (optional)

Up to 14 optically-isolated multi-purpose AC /DC inputs mapped into programmable logic or for reporting SCADA points through DNP3.0 or MODBUS (optional)

Operates over a wide voltage range of 38 to 160 VDC or 120 VAC

Mounting available in either a 304 Stainless Steel NEMA 4X enclosure, heater option available, or metal enclosed panel mounting enclosure

Substation hardened to ANSI Fast Transient and Surge Withstand of C37.90.1 and RFI/EMI requirements of C37.90.2
