Large or small, each and every industrial, commercial, and institutional organization needs to understand how to protect their investment in their electric power systems.
The task of the electrical unit protection is to detect electrical failures and inadmissible operation of the generator, generator bus bar, excitation system, generator transformer, and another existing transformer (Station transformer, unit auxiliary transformer) and disconnect faulty circuits with speed and certainly without interference healthy circuits.
An automatic synchronizing unit is furnished for connecting the generator unit to the grid via the generator circuit breaker. It is also possible to connect via the circuit breakers in HV substation if the generator circuit breaker is already closed.
The universal transducers allow measurement of all electrical quantities occurring in any network in a single unit. Especially in power plants and substations transducers are used for isolation of electrical signals and for further processing of measured values.
