Mobile Transformer Substations 154 kV
Eva-Mobile-154 series are HV / MV mobile substations that convert the energy coming from the electrical transmission network from high voltage into the medium voltage by means of the step down transformers as these transformer step down the transmission lines high voltage from (110 – 132 – 154 – 245) kV to (6.3 – 10.5 – 17.5 – 20 – 34.5 – 40.5) kV which fall under the medium voltage distribution network. Mobile Transformer Substations are manufactured on a mobile platform with a capacity of up to 60 MVA for the purpose of temporarily feeding various facilities as well as to meeting emergency needs and other various requirements.
These reduced voltage stations are installed over two trailers consisting of four main parts. These parts are high voltage protection and conversion equipment, high voltage to medium voltage transformer (power transformer), medium voltage cells (GIS / METAL CLAD), protection and control panels, which fall under low voltage.
These stations consist of the following parts:
High Voltage Switching Compartment 110- 132- 154- 245 (kV);
-Line disconnector and grounding switch
-Voltage and current transformers
-High voltage power transformer (HV- MV)
-Low voltage distribution transformer (medium voltage- low voltage)
Medium Voltage Switchgears Compartment (6.3- 10.5- 17.5- 20- 34.5- 40.5) kV;
-Air or Gas Insulated Medium Voltage Switchgears (GIS) or METAL CLAD units.
Protection and Control Compartment;
-DC power supply
