ABSTRACT
The main advantage of the power system protection devices when a short circuit or abnormal electrical quantity (current, voltage, power, frequency, etc.) changes, constitute the principle of protective actions, but also other physical quantities, such as the failure of the transformer tank With a large number of produced gas and oil flow rate of increase or hydraulic strength increased. In most cases, no matter what kind of physical reaction, protection devices include measuring part (and the constant adjustment part), the logical part, the operative part.
Relay protection and automation of power system failures and jeopardize the safe operation of the abnormal conditions to investigate the accident
countermeasures against automated measures. In its development process due to have a contact relay is mainly used to protect power systems and their components (generators, transformers, transmission lines, etc.), so from harm, so along the said protection. Basic tasks are: when the power system failure or abnormal conditions, in the shortest possible time and the smallest in the region, faulty equipment automatically removed from the system, or a signal from the duty to eliminate root causes of abnormal working conditions, to reduce or avoid equipment damage and power of the adjacent areas
