Company A is a high voltage equipment manufacturer. They produced high voltage
transformers rated 300 kV and above. All high voltage tests such as AC, DC and
impulse have been conducted to the equipment. However, they have been
penalized due to non-compliance issue. Justify the root cause of this problem and
support with relevant facts.
