The difference between single-phase and three-phase voltage

The difference between single-phase and three-phase voltage, simple and composed voltage it is basically in their value. To explain the difference between single-phase and three-phase first you need to understand that the composed voltage is √3 times bigger than the simple voltage, in other words, V(composed)=V(simple) x √3  (approximately 1,732).  This difference can be identified with a voltmeter. For the composed voltage we measure the voltage between the two phases, and for the simple voltage, we measure the voltage between the phase [...]

How can you verify the necessary power for a generator?

There are several methods to calculate or verify the necessary power for a generator, learn the process and how to know which genset you need to purchase. Mainly in Portugal at major projects, the designers have at their responsibility the calculation to verify the necessary power for a generator and then define it in the contract documents of the project. In the case of private individuals, they are the ones responsible for this calculation, so the solution is to check the [...]

In the generators, the combustion and the fuel tank are a key element, because it’s the tank that defines the genset's autonomy. Generally, the tanks are selected and designed so that, the genset can operate in full load (100%) at least for 8 hours. Depending on the engine consumption we provide in the standard range tanks from 40L to 1000L. In the [...]

Military Project from an engineering perspective

The gensets in this military project characterize for having very complex specifications, which have many requirements and details that are destined to ease the usage of these gensets. Through the development of this military project, we intended to create a system of fast implementation where every element must allow an optimize assembly and disassembly since we have as base the Plug & Play with the purpose to facilitate the user on set. The engineering equipment resulted in two types of power [...]

The process of a military project

Recently we had a big project in Grupel, a military project that had a great level of concentration and demand from every department. The process in this military project started through a tender to develop and manufacture the energy solution. After this process, the starting point was the negotiation, like usual, when it comes to develop and manufacture a project the process of negotiation is intense because it is necessary to discuss costs and more importantly the technical solutions. Since Grupel already [...]

Precautions in the Generator Installation

Most of the gensets in Portugal, function in the emergency system, and for that, it is necessary to guarantee the good functioning of the generator installation and its precautions. For that we must guarantee: A good fresh air intake:For the genset to cool and for the combustion of the diesel engine, the installation location should contain an opening for the fresh air intake (cold) directly from the exterior A good hot air outtake:It is also very important that the [...]
