CCUPT 203
Applications
The system is used to measure the oil /winding temperature of an oil-immersed Transformer, transmit the measured value to a remote point by dc current mode and provide two independent channels of dc current signal at the remote point. This system is electrically isolated from input power supply and hence is safe to use in computers for SCADA or other Data Acquisition purposes.
