HARMONIC MITIGATING TRANSFORMERS
Harmonic Mitigating Transformers are used for reducing harmonic currents. Treating harmonics has many benefits, including:
- Lower maintenance and replacement costs as a result of reducing the amount of heat harmonics can generate.
- Operation of the transformer at a lower temperature due to less heat, eliminating overheating and excessive operating temperatures.
- Lower cooling cost in the area where the transformer is installed as a result of reduced operating temperatures
- Uses the full capacity of the transformer. There is no need to de-rate the transformer below the nameplate capacity because of the reduction in heat.
Features, Benefits and Functions
- 480 volts delta primary and 208Y/120 volts secondary standard rating. Additional voltage combinations are also available.
- Electrostatic shield for attenuation of high frequency noise.
- 150°C, 115°C, or 80°C temperature rise
- Copper windings and terminals as standard. Aluminum is optional.
- Meet or exceed NEMA TP-1 energy efficiency levels.
- 200% rated neutral.
- 220°C, insulation system.
- Performance validated by a nationally recognized independent testing facility.
- Eliminate circulating harmonic currents in primary windings of transformers.
- Low zero sequence impedance and zero sequence reactance.
- Enclosures are NEMA 2 drip-proof. The addition of optional weather shields makes the enclosure NEMA 3R rainproof.
- Harmonic cancellation via electromagnetic flux cancellation. Filters, capacitors or other such devices are not used.
- Variety of phase-shift options available to treat specific harmonics in a system.
- Helps meet IEEE 519 harmonic limits.
