Basics about Diesel Generator Sets

What is an alternator Automatic Voltage Regulator (AVR)? An automatic voltage regulator (AVR) is an electronic device that serves to regulate & maintain the output voltage of the alternator at a set value. It will try and do this as the alternator load or operating temperature changes. The AVR is part of the alternators excitation system.

Diesel Generators are generally installed for buildings or at those places where the emergency or standby power supply is needed. Before using a generator, it is necessary to keep an eye on the earthing or grounding of the dg set as it is important to ensure correct operation of the dg set and safety of the people nearby the unit. Hereby we are going to introduce something about the dg set earthing grounding or earthing.

Like other common mechanical equipment, diesel generator sets also require daily repairs and maintenance. The following 9 tips can help you to make the service life of a dg set longer and make the operation process smoother.

Normally, when the mains power is restored, the ATS will switch from the diesel generator set terminal to the mains power terminal, and then the diesel generator set will still run for a period of time (usually around 45-90s according to the setting). This is normal situation. The diesel generator set will automatically stop after cooling for that period of time. But sometimes we find that the unit cannot be shut down. Hereby we will talk about the possible reasons and solutions when a diesel generator set fails to stop running.

Batteries are an essential part of the starting system for a diesel generator set. Batteries are so important to generator operation that the battery is often the first thing a service technician will check when a generator fails. The most common reason for generator failure is a failed battery. This article will introduce some information about batteries' roles, types, connection, charging, maintenance, selection, etc.

Diesel powered generators are known for their fuel efficiency, reliability, long service life and wide application. However, they still have the problems or malfunctions that they should have as well as other machines. One such problem is overheating. Overheating can be caused by a low level of coolant, coolant pipeline blockage, improper use, insufficient lubrication, clogged exhaust or a problem with the generator.

Hereby we will introduce the AC voltages (V) and frequencies (Hz) of countries all over the world. Not all countries use the same AC voltage and frequency.
