Dry-Type Isolation Transformer
Features of Dry-Type Isolation Transformer
1. High level of isolation
2. Provides excellent protection against N-G disturbances (also known as Neutral to Ground Disturbance)
3. High level of common-mode noise rejection
4. Offers conversion of a delta system to a Wye-connected system, vice versa.
5. 3-phase isolation transformer loop taps for quick and easy voltage adjustment.
6. Designed according to customer requirements.
Standards
IEC60076
GB10094
Operating Conditions
1. Altitude: ≤5000m
2. Ambient temperature: -15°C~ 45°C
3. Relative Humidity: ≤90%
4. The workplace where our isolation transformer is to be installed should be free of gases, steam, chemical deposits, dirt, conductive dust, and other corrosive, explosive or inflammable substances that might affect the insulation performance.
Applications
Delta to Wye Conversion
1. In power grids where third harmonic currents and common-code noise are a serious factor to consider, the delta-wye transformer can prevent these disturbances from entering the supply line.
2. The delta-wye transformer provides a new neutral-to-ground connection, which means added protection for the end-user equipment.
Wye to Delta Conversion
1. The Wye-Delta transformer prevents distorted current waveforms caused by non-linear loads.
2. Users can sample the electric current waveform at the input end of the Wye-Delta transformer to check if current distortion exists.
3. A Wye-Delta transformer can operate even when unbalanced loads are experienced on the power supply line.
