Introduction

Electrical energy has extensive use in our daily life

Most customers believe that utilities have caused the problem

Electrical pollution have significant effect on electrical motor and other equipment operation

Electenergy Technology Inc. (ETI) of USA has technology to deal with this electrical pollution

Introduction

What is ElectroFlowTM ? ElectroFlowTM is one-of-a-kind, state-of-the-art energy

saving and power conditioning system

It is an integrated system equipped with a microprocessor based Regulator, which monitors V, I, PF., and Hr. at the rate of 3840-15360 samples per second.

It is specifically custom engineered to optimize power quality and guaranteed savings

It is versatile solution and available for various load sizes and voltages

It is an integrated system consisting of LRC circuits It is equipped with a unique alarm-driven Self Diagnostic

Feature(SDF) It eliminates the need to purchase a number of different

devices

Benefits of ElectroFlowTM

Reduces facility’s energy cost up to 34% Reduces equipment downtime and

maintenance Increase plant’s reliability Makes it possible to increase the total

connected load of a circuit without over sizing the existing hardware

Protects company’s investment Provides protection to sensitive equipment

Voltage Improvement and Stability

Problems due to voltage variation-

Motor bearing failure Reduce production quality Waste energy/High electric bill Waste investment and operating capital Call for oversized machinery More difficult to provide adequate

overload protection Increase noise and vibration Increases maintenance of equipment and

machinery

Voltage Improvement and Stability

ElectroFlowTM Offers-

Real time voltage improvement and stability Saves energy Connects in parallel and it is fail safe It is modular and expandable

Disqualification of other similar products (UPS, SPS) -

Waste energy Connect in series Generate harmonics Limited fixed sizes and not expandable Bulky and expensive

Three Phase BalancingProblems due to unbalance loading-

Negative voltage sequence Circulating currents Increased current in neutral conductor Increased Neutral- to- Ground voltage Overheating of motors/Insulation breakdown Reduced motor efficiency Motor bearing failure Increased maintenance of equipment and machinery Wasted energy/High electric bill Wasted investment & operating capital

Three Phase Balancing

ElectroFlowTM Offers-

Real time phase balancing based X/R Saves energy

Disqualification of other similar products -

There is no such device known in the market

Surge and Transient ProtectionProblems due to surge and transient-

Increase maintenance and downtime Reduce lifetime of equipment Cause computers to stop execution of programs Creates false data in computers Erase data in computer memory Result in hardware damage Cause damage to insulation in transformers and

motors Cause nuisance tripping of adjustable speed drives Wasted energy/High electric bill
