Bushing insulators and accessories for power and distribution transformers
R.I.S.
R.I.S. (Integrated Safety detector)
R.I.S. (Integrated Safety detector) was conceived from the need to integrate the functions performed by a number of electric transformer accessories in a single, compact and reliable instrument. In fact it gathers in just one device the functions of controlling pressure, temperature, oil level, and gassing in oil insulated electric transformers. Please contact our Sales department in case you need further information and/or catalogues.
Summary of its functions
PRESSURE
Pressure switch: closes/opens a circuit on pressure ranging (from 100 up to 500mbar).
TEMPERATURE
Thermometer: visual representation of oil temperature and maximum temperature reached
"T2" Thermostat switch (alarm): closes/opens a circuit at a predetermined temperature level (from 30°C up to 120°C).
"T1" Thermostat switch (stop): closes/opens a circuit at a predetermined oil level (from 30°C up to 120°C).
OIL LEVEL
Indicator: visual detector of any slight variation in oil level
Detector: visual detector of any significant variation in oil level through closing/opening of an electric circuit.
GASSING
Detector: closes/opens a circuit when the maximum gas volume is reached (max. 170 cm3).
