Many installation sites need electric power for construction activities. When the site not large all construction equipments are powered with single phase supply. Such single phase DG sets may be available. Site gets single phase supply from utilities for construction. A new construction equipment requires a three phase supply. We have three DG sets of…
Generator voltage drop causes: 1). Load applied to generator exceeds capacity, typically would cause machine to slow down, drop frequency and voltage typically cause exhaust black stacking and depending on the overload and protection settings could cause machine to stall. 2). AVR Voltage gain set too low to respond to load being applied. 3). If…
Brief introduction The following problems listed below are provided the following: Known problems Possible causes of the known problems Repair to correct the known problems Fault diagnosis 1). When the starting switch is in the (ON) position, the engine crankshaft does not rotate. Possible causes: 1. Low battery output voltage Check the battery status…
Generator Protection: A generator is subjected to electrical traces imposed on the insulation of the machine, mechanical forces acting on the various parts of the machine, and temperature rises. These are the main factors which make protection necessary for the generator or alternator. Even when properly used, a machine in its perfect running condition does…
Why Generator Load Testing: The purpose of most generator sets is to provide a reliable source of power to your facility or commercial operation during an emergency situation when power from the grid is suddenly lost or is not available in your environment. In the event of a power failure, you should have peace of…
Alternator Vs Generator Alternators and generators are two devices which generate electricity. Both alternators and generators convert mechanical energy into electrical energy. An alternator can be called a type of generator. Although both these devices serve the same function, they are quite different in every other aspect. An alternator is a charging system for cars…
Generator is the important power supply equipment to generated electricity. Without electricity, we cannot operated machinery, equipment, lighting, computer and others device for our living. For general power supply, power distributor normally used the high capacity of generator to supply the electricity to the consumer. It different size for backup power supply that used for…
A generator is a device that converts mechanical energy into electrical energy. Generators do not produce electricity on their own, they must first collect mechanical energy from an outside source. How a generator works is easy to understand if you can understand each step below. Common sources used to supply a generator with mechanical energy…
Connecting generators in parallel increases the power capacity, control in load management, ease of maintenance, and redundancy. The process involves the physical connection of two or more electric generators, and the synchronization of their outputs. The synchronization matches the waveform of the output voltage of one generator with the voltage waveform of the other generator…
Backup Generator or UPS for Your Business? There are few things that are more disruptive to a business than interrupted power supply. Whether your business relies on computers alone or complex machinery, it cannot operate without power. In areas where power failures, blackout or brownouts are common, or where equipment uptime is critical at all times,…
