ТR-100М is microprocessor based device intended to measure and control temperature mode of dry-type transformer with four transducers connected by two or three wire circuit, with subsequently displaying the temperature on the display and sending alarms when any parameters are outside preset limits.
The product can also be used for protection of HV motors and generators.
The product has universal power supply of 24 to 265 V (AC or DC) and connection to network EIA/TIA-485 with MODBUS RTU / ASCII protocol.
The product can be applied with the following types of temperature transducers:
– PT100 – platinum transducer with rated resistance of 100 Ohm, at 0°С;
– PT1000 – platinum transducer with rated resistance of 1000 Ohm, at 0°С;
– PTС1000 (EKS111) – transducer with rated resistance of 990 Ohm, at 25°С;
– PTC (minika) – cold resistance of transducer of 20-250 Ohm.
The structure of ТR-100М is made in plastic housing designed for mounting on the front panel of the board (cabinet) or of the device; dimensions of the housing is 96 x 96 x 110 mm. The housing is made of shockproof, self-extinguishing material.
The product has four channels for temperature measurement, and four output load relays. Each load relay is designated for a particular control parameter (like On/Off cooling systems, Alarm, Tripping, Sensor fault).
The temperature transducers (sensors) of the first three channels measure the temperature of each transformer winding; and the fourth one measures temperature of the transformer yoke or ambient temperature.
In case of dangerous temperature rise of the transformer, the product first will enable alarm system and the cooling fans. If the temperature rise continues and the temperature exceeds the limit value, the product will perform emergency shutdown of the transformer.
In case of temperature sensor fault, TR-100M enables the alarm of the transducer fault.
