Manufacturing for this product has been discontinued.

The transformer tap changer controller DTR controls automatically the transformer on load tap changer, so that the power supply  voltage is practically constant, independently from the load. In order to achieve this, the DTR is able to increase and decrease the OLTC in the power transformer. 
 

• Control power transformer OLTCs to regulate voltage

• Automatic voltage regulator
• Automatic/manual operation
• Three setting tables
• Configurable inputs and outputs
• BCD format inputs to detect tap changer position

• I, V, P, Q, cos j, frequency measurement
• Transformer OLTC position
• Event recording
