Passive Filter Reactors

De-tuned Filters

Detuned filtering is a reliable and time-tested method to improve the power factor and also mitigating the risk of resonance; this is achieved by shifting the resonance frequency to lower levels, thereby ensuring that no harmonic currents are present.

The method is simple; by changing the basic LC circuit formed by the transformer and the capacitor banks, by way of introducing a filter reactor in series with the capacitor; this makes the circuit a more complex resonant circuit but with a resonance frequency below the first existing harmonic. In this way a real resonance condition cannot arise. The components for the detuned filter need to be selected very carefully, after a proper harmonic study is conducted.

Our Available Range : 5.67% , 7% , 14% Detuned reactors available in the range from 5 Kvar to 100 Kvar single bank.

Thyristor Switching Modules

Thyristor Switching Modules are free of Mechanical Wear and Tear, operate without noise, and provide practically transient free switching eliminating inrush currents which are associated with Electromechanical Contactor Switching. An unlimited number of switching operations are possible, without applying significant stress to the capacitors.

• Four LED indications : Thy Switch 1 and 2 ON ( Current Flow condition ), Power ON, Ext. Signal ON.
• Cooling Fan : ON automatically, when switch temperature rises above 60 degree.
• Over Temp. Trip: When temperature exceeds 90 degree due to cooling fan failure.
