Benefits of Variable Speed Drives

11th March 2013 | Posted by Charlotte Miskell

Benefits of Variable Speed Drives Variable speed drives are becoming more popular due to the fact that they are able to vary motors’ output speeds without the need for pulleys, extraneous components or a great deal of maintenance. There are many benefits to VFDs. The most significant being the significant energy savings achieved by matching system capacity to the actual load for the duration of the year. Variable Speed Drives can reduce wear and tear significantly. Through drawing a much higher current upon the starting of the induction motor, the inrush of current may be between 3 and 10 times the full load operated current. This generates both heat and… Read more »

We Advise On Control Gear & Switchgear Saftey Precautions

11th March 2013 | Posted by Charlotte Miskell

Perhaps the most obvious danger to those carrying out electrical switch gear testing is the threat of an electrical shock. Any connection between a live connection and a body connected to the ground will result in an electric shock, varying in danger depending on the voltage level. Should conductors be short-circuited accidentally, there is an additional risk of burning from arcing. Electric shocks or dangerous reactions to them (e.g. through falling or in touching another object) frequently occur during testing and repairs carried out on control gear and switchgear, particularly when there are large areas of earthed metal. High voltage flash testing can also be extremely dangerous when numerous parts… Read more »

8 Soft Starter Uses & Benefits

15th March 2013 | Posted by Charlotte Miskell

Soft starters are available in a huge variety of sizes. From a miniature soft starter no larger than your average pack of playing cards to larger soft starters built to take on bigger duties – such as starting a ship’s engine, controlling the electrical flow and starting auxiliary motors such as air conditioners, when required. There are many benefits to the implementation of soft starters, in this post we seek to highlight the top 8! – Through use of a soft starter, it is possible to monitor and run diagnostics for motors, as well as protecting against voltage spikes, over-heating or internal faults. – Smoother acceleration can be achieved as… Read more »

What Are Motor Soft Starters?

18th March 2013 | Posted by Charlotte Miskell

If you are looking to implement a soft starter in your circuit, here at Proplas we install and commission soft starters for all applications. In our latest blog post, we run through the basics of these mechanical/electrical devices… A motor soft starter is used in conjunction with AC electric motors in order to reduce the load and torque of the motor during start up. Reducing the stress on shafts, motors and power cables helps to greatly extend the life spans of the electrical or mechanical systems. Soft starters are comprised of either mechanical or electrical components, or can even be a combination of the two. Mechanical soft starters are inclusive of clutches and numerous forms of couplings through  use of fluid or magnetic force to transmit… Read more »
