Principais Falhas no Arranque de um Gerador

The Reasons Why the Genset Fails to Start

Preventive maintenance is very important to prevent failures on the genset functioning. However, an unexpected failure can happen for several reasons. Below we present the main reasons why the genset fails to start: Battery failureMost of the failures on the genset startup are related to the battery. A significant percentage of this fault is due to the accumulation of lead sulfate in the battery plates which ends up by disabling them. The purchase of a battery without maintenance it is [...]

Portable Generator Grupel

Portable Generators, Flexible Range, Resistant and Practical

Recently we added to our portfolio of products a new portable generator Grupel (3000rpm), the gasoline portable generator of 8kW Single Phase & Three Phase. This new portable generator provides the possibility to function under two options (single-phase and three-phase) in just one equipment, this version has better finishes, it is more robust and has an alternator of higher quality. Just like in the other models, it is necessary to have certain cares as: before turning the generator on, ensure that [...]

Genset power factor

Understand the meaning of a genset power factor

Discover the different types of power kW, kVA, kVAr and its relation with the power factor (cosine of Fi (φ)). To understand the genset power factor, first, we will start by exploring the different types of power, on which the kW (kiloWatt – active power), the kVAr (kiloVolt Ampere reactive –reactive power) and the kVA (kiloVolt Ampere – apparent power) are electrical power measurements. The kW is the power that generates work, kVAr is the used power that creates and maintains [...]

Electric voltage and electric current

Find out the relation between voltage, current, and electric resistance 

The electric voltage (U) and electric current (I) are very different concepts, better known as voltage and current. It is impossible to refer to electric voltage and electric current without mentioning the law of all laws, the Ohm's law, that has the following relation:Where:R: Electric resistance, in Ohm (Ω) U: Electric voltage, in Volts (V) A: Electric current, in Ampere (A)Basically, the electric resistance is the easiness or difficulty that the materials have, to opposed to the electric current passage. When is [...]
