Equaliser Features explained:
The key to the super fast capacitor bank switching lies within the heart of the switching module. Its comprises of solid state switching elements that provide reliable,high speed ,transient
Single, double or three phase switching is available.
Switching modules are designed specifically for the capacitor bank groups, current requirements and voltage rating.
The controller comprises of a digital signal processor (DSP). This unit has 9 input channels and 4 voltage input channels. The information gathered is used in a fast fourier transform (FFT). An advanced algorithim, which is patent pending, calculates the fast compensation faster than 1m/s.
3. Capacitor/reactor module
The Elspec equalizer capacitor cans are MKP-type capacitors which are low loss units (0.25w/Kvar) housed in cylindrical aluminium casings. The MKP type cylinder cans contain metalized polypropylene films with self-healing properties and an overpressure tear off fuse.
To reduce the effects of electrical and thermal overload and to extend the life expectancy of the units, the capacitors connect during zero current crossing and operate in a time sharing mode called SCAN.
Reactors are manufactured under tight control measures to ensure the quality required. They are constructed with quality laminated, low hysteresis loss iron cores, copper windings, precision controlled air gaps and Class H insulation (180 C).
Types of reactors :
In-rush Reactors design to limit in rush current during start up of the capacitor.
De-tuned Prevent resonance conditions by shifting the capacitor/network resonant frequency to below the first dominant harmonic ( usually the 5 or 7 resonant)
Tuned Desgined to absorb a majority of the dominant harmonics usually 5 or 7.
The Equaliser switches capacitor groups on and off using state of the art electronic odules/switches. The connection and disconnection of the capacitor banks are controlled by the Equaliser switching module which ensures that this occurs are precisely zero-current crossing. This smooth connection and disconnection guarantees smooth transient free switching, unlike the electromechanically switched (PFC) units. It also extends the life of the Equaliser capacitor banks.
