Description
Detuned Filter Reactor – DELAB/ Made in Malaysia
Detuned Harmonic Circuit Filter Reactor is used for:
1) filtering harmonics and high frequency disturbance.
2) Reduce High inrush current (from parallel switching of capacitors & from power to capacitor banks and thus improves the operating source life span of the capacitor.
Filtering % p is the ratio of inductance to capacitance. It is not to be confused with the impedance or reactance of an inductor.
For a 50Hz system:
1) p=7% = 189Hz is used where protection to capacitor
and harmonics reduction is required.
2) p=6% = 204Hz is to be used where the system is rich
in 5th harmonics & above.
3)p=13% = 139Hz is used where voltage distortion
exceed permissible limit
