At Johnson & Philips, we take great pride in our fleet of vehicles that enable us to travel upon all-terrains. Some sites that we visit may not be suitable for our vans and this is why we are investing into additional 4×4 vehicles. Unlike other companies that simply rely on their vans, our team have […] Read more
Due to the technological advances over the last decade or so, most businesses constantly use advanced systems. Due to the fact most businesses rely on power, its crucial that all safety procedures have been taken. At Johnson & Phillips, we are constantly called out to help recover power outages of all types. The costs of […] Read more
When it comes to the efficiency of power transformers and other equipment, you may see the term harmonics mentioned. Harmonic currents and voltages are integer multiples of the fundamental frequency of the system. Harmonics created by faulty equipment with nonlinear loads can result in more current in abrupt short pules. This will cause current waveforms […] Read more
Servicing Your Power Factor Correction Equipment
At Johnson & Phillips, we are one of the leading UK companies that deal with power factor correction equipment maintenance. The benefits of PFC are fairly well known in the industry with huge financial savings, carbon emission reduction and more capacity being the main benefits. However, once you have installed power factor correction equipment, it will […] Read more
33kV to 11kV – What is the Process?
33kV to 11kV transformers steps down the the voltage to a safe level, which is then distributed via 11kV feeders to homes and businesses. Many people question why the voltage is as high as 33kV in the first place. The reason is that the higher the transmission voltage, the lower the transmission losses will be. […] Read more
What is Power Factor Correction
Power factor is the ratio between the true (useful) power kW to the apparent (total) kVA consumed by a complete electrical installation or piece of electrical equipment. It is a measure of the efficiency of the electrical power and how much is useful electricity. The optimal power factor is unity or 1ing . This means […] Read more
Voltage Optimisation vs Stabilisers & Regulators
At Johnson & Phillips, our voltage optimisation services goes much further than companies that use just a stabiliser or regulator. As discussed previous, a voltage regulator is often referred to as a step down transformer. The stabiliser is a bit more complex but it can be described as a voltage regulator with added electronics that […] Read more
Voltage Optimisation vs Step Down Transformers
Voltage Optimisation and Step Down Transformers are often considered as the same technology but they are not at all. In short, a step down transformer simply changes the voltage from low to high whereas a voltage optimisation unit will correct the power supply. Below we discuss the two technologies in more detail and break down […] Read more
