Medium or High Voltage power generation is typically used where the power rating causes current at Low VoltageLV to exceed practical limits. In a practical sense, this occurs when the system capacity exceeds 4000 amps or more.It may also be desirable when power must be distributed to points at a significant distance from the generator set.Single generator rated at above 2.5 MVA and paralleling generators rated at above 2 MVA are good exaples of equipment that is commonly considered for MV applications.MV alternators are not economically pratical at less than a proximately 1000 kW. At levels less than 1000kw, it is probably desirable to consider the use of a low woltage machine with a step up transformer.When designing an MV or HV installation, consideration must be given to the training and qualification of the personnel operating the system owing to the higher level of safety precautions requried with these systems.
In the generator systems where the medium voltage alternator is used;
- Conduction losses and voltage drop are reduced,
- The productivity of the distribution system is increased,
- Installation and maintenance costs are reduced.
- Since there is no need for bulky cabling, both the image is intact and the safety is increased.
In Arken Generator, such technical infrastructure and engineering projects are taken seriously and after the detailed analysis and evaluations are made, project planning phase is started. As an example of Medium Voltage Generators, prime 8000 Kva 1000 Volt synchronous diesel generator sets with autonomous working and sound proofed cabin can be given as a backup power source to the network energy used in Anatolian Side Justice Complex in Istanbul which works perfectly.
