Diagnostics to prevent the effects of catastrophic failures and anomalies in the power system

Diagnostics preventing the effects of catastrophic failures and anomalies in the power system using a mobile rapid response team is aimed at:
a) recognizing the size of the failure, identifying its causes and assessing its effects,
b) performing post-failure tests and measurements of the following devices:

• power and distribution transformers,
• generators,
• circuit breakers,
• current, voltage and combined transformers,
• power capacitors,
• generator sets,
• compensation chokes,
• other station equipment

c) determining the scope of damage and the possibilities of its elimination,
d) putting the devices into operation after they have been repaired or replaced with new ones.

The scope of the tests includes:

• comprehensive diagnostic tests of the above devices on power facilities, covering all activities undertaken to check the operation or condition of the device in terms of electrical and mechanical properties,
• measurements and technical analyses regarding the causes of their failures in network systems,
• laboratory analysis of the technical condition of equipment and devices,
• tests, tests and measurements and expert opinions of power supply systems for electrical devices.

After performing the measurements on the facility, the measurement results are analyzed and then sent for evaluation by experts, who compare them with the laboratory results located in databases at the company's headquarters.
Such activities will streamline the failure assessment process and speed up repair actions.
