Following are the products which are about to launch soon.
Automatic Voltage Regulating Relay FE-2205
- Automatic Voltage Regulating Relay ( AVR ) is a device which is placed in control cubical panel for controlling voltage at secondary side of transformer.
- As the load changes at distribution end, line voltage changes accordingly. To keep utility voltage within limits AVR will generate control signal in the form of control pulses. ( Raise and Lower )
- The AVR delivers control signal to OLTC, which changes the tap accordingly.
- This AVR will be equipped with in built Tap Position Display and the Live Time Delay Display ( used when voltage exceeds preset limits, from 10s to 120s ).
Winding Temperature Transmitter ( WTT ) and Oil Temperature Transmitter ( OTT )
- WTT and OTT are a type of CCU ( Current Control Unit ) which transmits the temperature of respective winding or oil of transformer, in the form of a 4-20 mA current loop.
- This current is then measured at remote terminal unit ( RTU ) and respective temperature is displayed.
- This devices will be equipped with two separate pairs of current outputs and PT-100 and CT sec. inputs for measuring temperature. Also for calibration zero, span and gradient settings will be user trimmable.
