SYSTEM FOR VOLTAGE REGULATION, CONTROL, PROTECTION AND MONITORING OF STATE OF CHANGERS UNDER POWER TRANSFORMER LOAD, VOLTAGE REGULATORS, CAPACITOR BANKS AND SIMILAR

摘要

System for voltage regulation, control, protection and monitoring of state of changers under power transformer load, voltage regulators, capacitor banks and similar", is preferably applied to power transformers (1) and voltage regulators and similar, through a microprocessor (2) it provides innovating functions that make up for deficiencies of currently existing voltage relays, highlighting pre-programming, by means of man-machine interface such as, for example, keyboard and display (3), or serial communication (4) of several settings and different voltage regulation parameters, each adequate setting for a certain prevailing load condition, performed by means of dry contact inputs (5), contact outputs (6) destined for self-diagnosis signaling and alarms (7); voltage regulation allows parameter selection to be made by means of daily and hourly programming through an internal clock (8); said system (S) also has the non-volatile memory function (9); CDC blocking function (10) that directly acts on the motorized drive (11) of the CDC; and maintenance assistant functions of the changer under load (10).
