POWER OPTIMISATION
Improve the efficiency of your business with Power Factor Correction and Voltage Stabilisation.
Power Factor Correction
Power Factor Correction (PFC) is an energy saving technology. Through improved energy efficiency, PFC can reduce electricity costs by eliminating Reactive Power Charges, reduce network losses and even free-up available power for plant expansion.
What is Power Factor?
Power Factor is basically a degree of electrical efficiency and in an AC circuit, the ratio between the useful power kW (true power needed to perform a task) and apparent power kVA (a combination of true power and reactive power – power drawn in addition to useful power but does not contribute to the task).
What is A GOOD Power Factor?
Power Factor is displayed as a figure between 0.01pf to 1.00pf. In simple terms, you can describe power factor as a % of electrical efficiency.
A perfect power factor is 100% and is called unity.
A good power factor in excess of 95% is normally deemed as electrically efficient.
A poor power factor generally understood to be less than 0.95pf and a perfect power factor as 1.00pf known as unity.
improvING Power Factor
Correcting poor power factor involves installing power factor correction equipment to manage the power factor. The solutions we provide are tailored based on the results of our initial analysis and are then tailored to each individual customer’s site needs.
Our solutions
Fixed Power Factor Correction:
Perfect for the correction of steady state electrical loads and individual motors.
Automatic Power Factor Correction:
Sometimes referred to as ‘bulk’ PFC as it tends to be installed at or close to the main electricity incomer, it corrects the power factor of the whole system.
Detuned Power Factor Correction:
Fixed, automatic or dynamic, for use on harmonic-laden systems or to avoid possible resonance conditions.
Dynamic Power Factor Correction:
Often referred to as ‘real-time’ power factor correction, thyristor-switched capacitor banks typically respond within one cycle for rapidly changing dynamic loads. This power compensation technology is also often used in voltage control applications.
Benefits of Power Factor Correction
- Improves renewable generation
- Reduces circuit currents and allows for connection of additional load
- Reduces maintenance costs
- Reduces energy costs by removing reactive power penalty charges on electricity bills
- Reduces availability, capacity and maximum demand-based charges on electricity bills
- Reduces transformer losses
- Reduces fuel consumption of generators
- Reduces carbon emissions
Voltage Stabilisation
Voltage stabilisation is the process of maintaining a constant voltage output from an electrical source normally the grid, even when the incoming voltage fluctuates, effectively protecting sensitive electronic equipment from damage caused by voltage surges, sags, or spikes.
Why does voltage vary?
Voltage on the grid can vary due to fluctuations in electricity demand across the network, with power stations adjusting output to match usage, causing voltage changes as electricity travels through the grid, and because of the use of transformers that “step-up” voltage for transmission and “step-down” voltage for distribution to homes, all while staying within a permitted tolerance range to ensure stable supply.
What is an acceptable voltage range?
While voltage can vary from the standard 230 volts from phase to neutral, it is designed to stay within a specified range around the nominal 230 volts, typically allowing for a -6% to +10% fluctuation.
How can I improve voltage consistency?
To improve voltage consistency involves installing voltage stabilisation equipment to effectively manage the voltage.
The solutions we provide are tailored based on the results of our initial analysis and are then tailored to each individual customer’s site needs.
Our solutions
Servo- Electronic Stabilisers:
Servo-electronic stabilisers utilise a servo motor to adjust the position of a variable transformer (also called a “dimming” transformer) based on fluctuations in the input voltage, effectively increasing or decreasing the number of turns on the transformer to maintain a consistent output voltage at the desired level.
Static Stabilisers:
A static voltage stabilizer works by continuously monitoring the incoming power supply voltage and using solid-state electronic components like IGBTs (Insulated Gate Bipolar Transistors) to adjust the output voltage to maintain a constant level, regardless of fluctuations in the input voltage.
Benefits of Stabilisation
- Protecting electrical appliances from damage caused by voltage fluctuations
- Enhancing equipment performance and lifespan
- Reducing equipment energy consumption
- Minimising maintenance costs
- Ensuring consistent power supply to sensitive electronics by maintaining a stable voltage level regardless of variations in the power source
