ElectroFlow PREMIUM  is an integrated power conditioning system, which applies to industrial and institutional facilities. It provides energy savings (kW, kWh and kVA):

• Specifically designed for each application
• increases longevity of equipment
• reduces downtime and maintenance
• Payback from 1 to 3 years

By improving power quality, ElectroFlow PREMIUM  enhances energy savings in kW, kWh and kVA.  (2% to 25% of electrical billing, upon rates and electrical conditions)

 

Technical description

Technically, it consists of multi-stage LRC tank circuits:

• For three-phase applications. 
• From 208V to 345 kV, 50 or 60Hz.
• Hybrid Configuration (Main and submains)
• Installed in parallel
• Equipped with a microprocessor based Regulator  which monitors Voltage (V), current (I), power factor (PF) and harmonics (Hr), 3840-15360 samples per second.

Basic system

ElectroFlow PREMIUM  system eliminates common issues linked to power quality;

1. Voltage Fluctuations
2. Phase Imbalance
3. Surges (up to 300,000 V)
4. Harrmonics (!EEE 519 Standard)
5. Power factor (over 94%)
6. KVA capacity

70% to 90% of electrical problems are generated inside the plant and utility can't provide any protection against these.

1- Voltage fluctuation

      Under Voltage, over voltage and voltage fluctuations have the following adverse effects:

• Overheating of motors, insulation breakdown, bearings failures.
• Speed variation in motors and rotating equipment, reduced efficiency.
• Increased noise and vibration.
• Reduced production quality and efficiency.
• Wasted energy KW, KWH.

ElectroFlow PREMIUM  offers Real time voltage improvement and stability,

2- Phase Imbalance

      Imbalanced currents have the following adverse effects:

• Negative Voltage Sequence.
• Circulating currents.
• Reduced motor efficiency.
• Overheating of equipment, disconnects, transformers.
• Increased maintenance costs
• Wasted energy, kW and kWH.

ElectroFlow PREMIUM  offers Real time phase balancing, based on X/R,

3- Surges

      Surges and transients occur at anytime and:

• Cause nuisance tripping of adjustable-speed drives.
• Increase downtime and maintenance
• Cause computers to stop execution of programs, create or erase data
• Resulting in hardware damage.
• Cause damage to insulation in transformers and motors.
• Reduce lifetime of equipment

ElectroFlow PREMIUM  offers infinite response to Surges and Transients,

4) Broadband Harmonics

      Harmonics are generated by non linear loads and cause:

• Overheating of transformers (K-Factor), and rotating equipment.
• Distorted voltage and current waveforms.
• Failed capacitor banks.
• Breaker and fuse tripping.
• Unreliable operation of electronic equipment, and generators.
• Wasted capacity - Inefficient distribution of power.
• Neutral overloading / unacceptable neutral-to-ground voltages.
• Wasted energy - Hysteresis losses, kW & kWH.
• Increased maintenance of equipment and machinery.

ElectroFlow PREMIUM  offers broadband harmonics filtering,

5- Power Factor

      Low P.F. causes the following:

• Possible power factor penalties.
• Increased line losses - I²R.
• Increased maximum demand (KVA)
• Wasted distribution / transformer capacity (KVA).
• Wasted investment and operation capital.
• Wasted energy – kVA, kW & kWH.

ElectroFlow PREMIUM  offers Power factor above 94%

      Capacitor banks (PFCC) happen to be more and more problematic:

• Over-voltage, unregulated supply.
• Susceptibility to surges and transients (reduced Z).
• Harmonics magnification.
• Resonance and overheating,
• "Ringing" effect during capacitor charging, oscillation.
• Capacitor cell failure.
• Increased torque and kW, based on percent loading.

ElectroFlow PREMIUM improves Power factor, with no capacitors adverse side-effects.

 

6- kVA capacity

• Avoiding unnecessary capital expenditure for such wasted KVA capacity
• Sufficient capacity released to realize some important load additions

ElectroFlow PREMIUM  offers balanced-capacity release in KVA.
