TECHNICAL SPECIFICATIONS

The T154 is an electronic microprocessor-based unit for the temperature monitoring and control of MV dry type and cast resin transformers. The unit ensures high levels of protection to elec-tromagnetic interferences and ease of use which have made it the standard for this application. It provides temperature control of 3 phase trans-former, and a fourth option for the core or the ambient temperature. Dry contact relay outputs, ALARM and TRIP, FAULT signal operation and start ventilation system (FAN).
