Product Detail
Dry type, natural air cool type for indoor use. Ventilating fan is needed in enclosed cubical. Iron core – constructed with low loss silicon steel. Air gaps – multiple gaps. High linear performance of reactor with less gap losses and noise.
Application
- To create a ‘detuned’ natural frequency with power factor correction capacitor. This eliminate system resonance with harmonics which will damage the capacitor bank.
- To reduce harmonics distortion and reduce the problems associated with this harmonics such as over heating of transformer and nuisance tripping.
- Reduce switching transient inrush current of capacitors. This will reduce the circuit breaker failure and flickers in the power system.
- The use of specific filtering factor requires careful system analysis. As a general rule,
- p=7% is the ideal combination for max. capacitor protection, harmonics reduction at min. cost.
- P=6% is used when increase reduction on 5th & 7th harmonics is required.
- p=14% is used in 3rd harmonics rich system. Offer max. capacitor production.
Features
- Dry type, natural air cool type for indoor use. Ventilating fan is needed in enclosed cubical.
- Iron core – constructed with low loss silicon steel.
- Air gaps – multiple gaps. High linear performance of reactor with less gap losses and noise.
- Aluminum wire and aluminum foil. For current above 60A. Alu foil is usually used.
- Alu wire and foil have been used as transformer conductor for more than 30 years.
- Alu foils also have higher ability to withstand short-circuit and transient switching current.
- Nomex® or equivalent insulation paper is used for layer insulation.
- Terminal – copper bar connection for current above 20A. JIS type terminals for lower current.
- Complete with over temperature, bi-metal 145ºC, normally closed thermostat.
