PC "Aurora Electro" LLC develops and manufactures TST syimetizing transformers, which eliminate Phase imbalance and unbalance of phase voltages and currents at symmetrical line-to-line voltages; Imbalance (asymmetry) of line voltages and input currents; Imbalance (asymmetry) of phase and line voltages; Overheating of zero working conductors of cable lines; Breakage of the neutral wire (neutral); Imbalance (asymmetry) of the currents of diesel generator sets and (or) UPS; The problem of redistribution of currents in three phases. Using various schemes and those. solutions we can produce any type of balancing transformer: TST is a three-phase alternating voltage balancing transformer. ТСТР - three-phase balancing transformer - voltage normalizer. TST, which converts three-phase voltage to single-phase. Balancing transformer that converts three phases into one. Balancing transformer with reactive power compensation function. Power transformer with galvanic isolation.
