Transformer Temperature Indicator

Transformer Temperature Indicator (WTI)is desiged for oil-immersed transformers, which can indirectly measure the winding temperature of transformers by thermal simulation method.
BWR series WTI covers with outside mounted current converter,but III model is with inside mounted current converter.

BWR series WTI main techinical data:
Working temperature:-40 a `~55a
Measuring range:0a ~150a or upon the customers' requirement
Accuracy:+/- 2%

Control capability:
1)Adjustable range:full span
2)Setting accuracy:+/- 2a
3)Switch differential:6a +/- 2a
4)Rated power:AC 250/15A
5)4 switches standard setting point:K1=55a K2=75a K3=90a K4=130a
Note:The switch quantity & setting point can be made according to the customers'requirement,and it comes with max.6 switches.

Out put signals:
1)without DC power 4-20mA
2)Pt100(model A)
3) with DC power 4-20mA(model D)
4)DC 0-5v(model E)
Bulb sensor dimension:dia14x115
connection:M27X2 or upon the customers' requirement
Protection class:IP55

Current converter main technical data:
working temperature:-40a ~55a
Input:0.6A~5A,Output:0.5A~1.75A
