Need some help here..
Alternator windings have provision of Pt100 3 wire RTDs embedded in them for measurement of winding temperature.
I am using XTR105 as per Figure 3 of data sheet http://focus.ti.com/lit/ds/symlink/xtr105.pdf. Temperature Range is 0 to 200 degC and Rz, Rg, Rlin1, Rlin2 have been selected as per Table 1. Additional filtering is done as per figure 5, with values as shown in the said data sheet.
The connection from the RTD at the Alternator end to the XTR105 is through a shielded cable approximately 8m long, with the shield terminated to the chassis at the control panel end.
It is experienced that the current output of the XTR105 varies continuously, resulting in a fluctuating display of the order of 30 degC. This triggers false alarms of winding overheating, and also makes recording the temperature difficult for the panel operator.
Any suggestions, please ?
