Risk management in power transformators manufacturing

Abstract

Power Transformers are capital goods that are very important for the stability of large power systems. Block power transformers are mounted on each hydro and thermal power plant with functional characteristics compatible to generator, while distributive power transformers are being central plant of each high voltage power station. Manufacturing of power transformers has the highest risk exposure during designing phase, manufacturing, final laboratory testing, transportation and mounting process. Risk management is especially important in this area due to the fact that every power transformer is unique product whose price reaches several million euros. Moreover, in case of late delivery or lack of power transformers, one power plant can’t be in operation, therefore the indirect damage can be very high for power system. This paper analyzes the aspect of risk during manufacturing process of power transformers in local environmental economic conditions.
