Grupel Circuit Breaker

What is the role and functions of the circuit breaker in a generator?

Not only of an alternator and an engine lives a Grupel generator. Therefore, we look carefully and in detail at all the elements that make up and contribute to the proper functioning of our products, which include sensors, switchgear, resistors and, among others, circuit breakers. We try to have more and more of these components in our own brand, because we believe that, investing on the quality of each piece, we can differentiate our final product, making it increasingly competent [...]

The heads of the commercial department and the Spanish [...]

Grupel’s Cogeneration System – Get to know the project

Grupel carried out yet another special project, this time using a system of simultaneous production of two or more types of energy - a Cogeneration project. A regular generator transforms the chemical energy that exists in fossil fuel (diesel, gas, biogas, among others) into electrical energy. Usually, through the combustion of the first, thermal energy is produced which then is transformed into mechanical energy inside the internal explosion engine. In turn, mechanical energy is transformed into electrical energy by means [...]

The difference between single-phase and three-phase voltage

The difference between single-phase and three-phase voltage

The difference between single-phase voltage and three-phase voltage, respectively, simple voltage and compound voltage, is basically in the value between them. The compound voltage is √3 times higher than the simple voltage, ie V (compound) = V (simple) x √3 (approximately 1.732). This difference can be identified with a voltmeter. For compound voltage, the voltage is measured between the two phases, and for single voltage, the voltage is measure between the phase and the neutral.An alternator that supplies single-phase voltage [...]
