What is Charging Alternator?

The charging alternator is simply a three phase ac synchronous generator with solid state, self-contained, rectifiers and regulators. The charging alternator is driven by the diesel engine via a belt and generators alternating current power. The ac power is rectified to a Direct Current power. The output of the charging alternator is connected to the starting batteries.

It should be noticed that this charger only charges the battery when the engine is running. Therefore if the genset is meant to be for standby duty then a separate electrical battery charger needs to be used.

Because the charging alternator regulator is contained within the alternator itself, depending on the frame for its ground return. This can result in incorrect voltage sensing by t he regulator and a separate ground return wire should be used from the battery to the alternator.

Now, let me introduce the basic information about static battery charger to you. Actually, the static battery charger is also called electrical or electronic charger. This charger converts the ac electrical power into DC power using different technologies depending on the manufacturer of the static charger. 

Typically, the static battery charger consists of the following points:

1. Electrical module to step down the AC voltage to a level which can be easily handled by the nest stage.

2. Rectification of the AC voltage to a DC voltage using full wave rectifier circuits or other technologies.

3. Control the output to maintain the DC voltage level within the limits by removing the ripples and leveling the DC output.

4. Optional metering instruments such as DC ammeter and DC voltmeter.

5. Optional low and or high DC voltage alarm relays with volt-free contacts.

6. Optional Current failure alarm relay with volt-free contacts.

7. Optional ground fault sensor with volt-free contacts.

8. Optional loss of input AC power relay with volt-free contacts.

Usually, static battery chargers have two charging states: one is Float Charge (or called trickle charge), the other is Boost Charge (or called equalize charge )

What Is the Difference Between Electric Motor and Electric Generator

An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and winding currents to generate force. In certain applications, such as in regenerative braking with traction motors, electric motors can be used in reverse as generators to recover energy that might otherwise be lost as heat and friction. An electric generator operates in the reverse direction, converting mechanical energy into electrical energy. Electric generator can be divided into various type, open type, silent type, trailer type, portable type and container type, etc. Electric generator is mainly composed of diesel engine & alternator. Electric generator set is mainly composed of engine, alternator, control module, and common base. Electric generator :- Electric generator is a type of machine which converts mechanical input (energy) into electrical output (...

Engine Fault Code Messages - Volvo Penta Engine

Volvo Penta Engine Fault Code When a malfunction has occurred and the diagnostic system has generated one or more fault codes, these are read out differently depending on the equipment used. Please refer to “Fault code messages”. If the system indicates that a fault code has been set: 1 Cut engine speed to idle, or shut the Volvo engine off. 2 For DCU/DU Read the fault code from the display, please refer to Reading fault codes via the DCU or Reading fault codes via the DU. For CIU press the diagnostic button and read the fault code, by observing the flashing of the diagnostic lamp. Refer to Reading fault codes via the diagnostic lamp, CIU. 3 Look up the fault code in the Fault Code Register chapter and take the recommended measures. Reading fault codes via the DU (Display Unit) Depending on the severity of the fault the text, either WARNING! or ALARM STOP (a buzzer sounds) will be shown on the display 1 Press any button to come to the fault list. The f...
