THREE PHASE ELECTROMECHANICAL VOLTAGE STABILISERS RTG range

front panel with voltage analyzer and fine output voltage regulation	Our range of electromechanical three phase "RTG" voltage stabilisers has been recently extended including five new models from 150kVA up to 500kVA supporting customers which required higher ratings with high levels of efficiency and accuracy. The regulation is independent for each single phase using toroidal voltage regulators of high power and fast regulation speed. "RTG" has digital voltmeters with input and output voltage readings on each phase and A-meters on each phase. Protection is assured by an automatic circuit breaker on input up to 100kVA, while fuse protection, automatic circuit breaker or main circuit breaker are available on request for higher ratings. Input and output connections are possible on each side and from the bottom side through an internal board.
The electronic control which gives the regulation assures an output accuracy less than 1.5% with the option of regulating the voltage within the 5% of the nominal output voltage. Manufactured according to IEC 60686 standards, it is not affected by power factor of load unbalance, and can be connected to a totally (100%) unbalanced load
