摘要
SYSTEM FOR VOLTAGE REGULATION, CONTROL, PROTECTION AND STATUS MONITORING OF CHARGERS UNDER POWER TRANSFORMERS, VOLTAGE REGULATORS, CAPACITOR BANKS AND CONGenerators, applies preferably to power transformers (1) and voltage regulators The microprocessor media (2) provides innovative functions that address the deficiencies of current voltage relays, especially pre-programming via human-machine interface such as keyboard and display (3) or serial communication. (4) of various adjustments and different voltage regulation parameters, each adjustment suitable for a given predominant load condition, made by means of dry contact inputs (5), with the contact outputs (6) intended for self-diagnosis signaling. and alarms (7); voltage regulation allows parameter selection to be made by daily and hourly programming via internal clock (8); said system (S) also has non-volatile memory functions (9); CDC lock function (10) acting directly on the CDC motor drive (11) and on-load tap-changer maintenance assistant functions (10).
