e²TANGO-2000-TRR Declaration of Conformity
Below you will find a diagram of an exemplary HV transformer bay with marked places of installation of the e2TANGO-2000 and e2TANGO-200 protection automation.
The presented solution covers a HV transformer bay, which includes all protection automation components based on the e2TANGO platform. The transformer differential protection (TRR), overcurrent and earthfault protection (STP) and voltage regulator (ARN) were built on the basis of the e2TANGO-2000, whereas the autonomous protection – i.e. the so-called ODR – on the basis of the e2TANGO-200 protection in the version with a capacitive container.
ADVANTAGES OF HV PROTECTION
Intuitive and user-friendly e2TANGO HV protection systems are equipped with a fully configurable, clear screen, as well as comprehensive configuration, registration and measurement functions. Readability of indications and signals, simple access to documentation and manuals, easy verification of the logic operation, as well as graphical verification of protection characteristics or remote service access greatly improve the daily operation of the device.
The e²TANGO series HV protection consists of two components, i.e.: the operating panel and the central processing unit (CPU). The CPU is made on the basis of expansion cards and is available in three enclosure versions: J6 (6 cards), J10 (10 cards) and J14 (14 cards) – depending on the complexity of a given switchgear bay layout and user needs. The e²TANGO-2000 operating panel has a 7-inch high-resolution colour screen.
