Medium or high voltage power generation is
often used where the power ratio causes the low voltage current to exceed
practical limits. In practical terms, this happens when the system capacity is
4000 amps or more. It may also be desirable to distribute power to points at
significant distances from the generator set. A good application of equipment
commonly considered for Medium Voltage application is single generator rated
above 2.5 MVA and parallel generators rated above 2 MVA.
Medium voltage alternators are not economically practical at a ratio less than 1000 kW approximately. It is desirable to consider the use of a low voltage machine of levels less than 1000 kW and possibly with a step-down transformer. When designing a medium voltage or high voltage installation, attention must be paid to the training and competence of the personnel operating the system due to the higher level of safety precautions required for these systems.
In generator systems where medium voltage alternator is used;
Arken takes such projects requiring technical infrastructure and engineering seriously. Project planning stage proceeds only after detailed analysis and evaluations are made. An example of medium voltage generators can be automatically operated, total prime 8.000 kVA 10.000 Volt synchronous diesel generator sets with sound insulation cabinet as backup power source to the mains energy used in Istanbul Anatolian Side Court of Justice which is still working perfectly.
