Smart Transformer for Smart Grid
The Smart transformer is one of EGYTRAFO’s new products. They are designed to monitor and manage the power supply during fluctuations and ensure getting optimum voltage when new demands are being added to the existing loads.
Smart transformers are intelligent enough to meet the requirements of upcoming power system, so they will be highly popular in the future. Moreover, they improve the reliability power quality and supply.

Smart Transformer Main Components
It consists of a distribution transformer that is manufactured according to the latest IEC standards and the Electrical Holding Company requirements. The transformer is made of the best quality materials that ensure the lowest losses and highest efficient performance. In addition to the following:
- On load tap changer compatible with the transformer size
- On load top changer intelligent controller provided with A.V.R device - Remote Terminal Unit (R.T.U)
- On load tap changer compatible with the transformer size
- On load top changer intelligent controller provided with A.V.R device - Remote Terminal Unit (R.T.U)
Smart Transformer Features
Controlling the transformer operation and performance
Protects the power system from load disturbance due to harmonicas, transient and voltage sage
Improves the power quality by summarizing load to get identical load current on each phase &Controls the o/p voltage of transformer by adjusting the tap position of the on-load tap changer using the built-in AVR
Monitoring transformer operation in service:-
Oil and winding temperature
Ambient temperature
Load currents and delivered load value
Pressure relay operation
Monitoring transformer operation in service:-
Smart Transformer Operation
The Smart Transformer can be operated manually, automatically and remotely using remote terminal unit (R.T-U)
