Above Attributes Table shows Specs for a Standard Harmonic Mitigation Transformer from Olsun Electrics
Olsun Electrics’ HM harmonic mitigating transformers are designed for non-linear loading applications such as those utilizing switch-mode power supplies. This type of loading includes computers and computer servers and related equipment such as printers, monitors and copiers… most any electrical equipment utilizing a resident power supply. Related applications include data centers, schools and office buildings, theater and recording studios, financial and similar institutions where single phase line-to-neutral equipment containing switching power supplies are used.
Utilizing flux cancellation and phase shifting designs, Olsun HM transformers mitigate third order (triplen) harmonics seen by the transformer, preventing primary winding coupling and the resulting noise that would be reflected back onto the feeding circuit.
Our line of dry type transformers encompasses 15 different product types—all of which can be ordered as low voltage or medium voltage.
LOW VOLTAGE: Up to 600 Volts [.6 kV]
MEDIUM VOLTAGE: 601 to 34,500 Volts [.61 – 34.5 kV]
