TPA-01 protection cabinet is intended for the implementation of protection and automation functions for 110‑220 kV HV power lines, and SIPS functions for voltage category 110 kV and above.
The number of functions in a single TPA-01 is limited by the number of analog and binary signal channels. The range of functions implemented in a single cabinet is determined by the design solution incoordination with the System Operator.
Each function can have an arbitrary number of steps, and remote starting elements can have an arbitrary trigger zone.
The functions are implemented in the FBD (Function Block Diagram) visual programming language according to the IEC 61131‑3 international standard.
In the event of a client having non-standard requirements, the FBD allows to customize the TPA-01 to take into account the corresponding facility`s special features.
