Advantages of Generator AVR

Longer life span
Delivering stable voltage can extend your equipment’s life span. Dealing with fluctuating voltage, especially too much, can affect your equipment. Giving your equipment the proper voltage consistently can reduce wear, minimizing repairs and costs.

 

Better protection
An AVR’s consistent voltage delivery protects your devices from voltage spikes and drops. Spikes create excess heat, potentially overloading and damaging your devices. With an AVR, you reduce the risk of spike and drop-related damage.

 

Enhanced performance
Consistent voltage also means better performance. Instead of dealing with fluctuating voltage levels, your devices consistently get the necessary voltage. They can operate more efficiently and effectively.

 

 

Applications of Generator AVR

Industrial Application

In factory or manufacturing environments, where heavy machinery is highly power-quality sensitive, a voltage fluctuation can cause machines to trip, halt production, or destroy automation systems. AVRs prevent these voltage spikes or dips from occurring, preserving the supply chain and minimizing economic losses due to machine failure.

 

Commercial Application

Office complexes, shopping malls, and commercial complexes all contain vital infrastructure, elevators, lighting systems, POS terminals, and server rooms. Having a stable voltage not only avoids equipment burnout but also ensures regulatory compliance and safety measures. AVRs ensure that there is an environment where operations remain smooth, even in the event of blackouts.

 

Home Use

High-end homes and villas can rely on standby generators for power supply for smart home networks, security systems, lights, and air conditioners. AVRs ensure there is a smooth switch over to generator power and will not damage appliances.

Installation Steps of Generator AVR
 

Preparation

Before beginning, ensure that the generator is turned off and disconnected from any power sources.

Locate the AVR Slot

Find the designated slot or mounting area for the generator regulator in your set generator.

Secure the Kohler AVR

Place the Kohler AVR securely in its slot, ensuring all connections match the generator’s wiring diagram.

Reconnect Power

Once the AVR is installed, reconnect the generator to its power source and turn it on to test the voltage regulation.

 

Precautions for Using Generator AVR
 

Visual checks
Technicians inspect all components for wear, fraying, corrosion, loose connections and overheated components. Spotting these early lets you correct minor problems before they become major issues.

 

Airbrushing
Technicians will airbrush your AVR components to remove dirt and dust buildup if needed. Clearing buildup keeps everything clean and prevents connection issues.

 

Voltage testing
Voltage testing ensures your AVR can handle different voltages while delivering consistent voltage to your equipment. This testing ensures your AVR can handle sudden fluctuations.

 

Calibration

Calibration aligns your AVR’s output with your desired voltage levels. Regular calibration is critical for safe, effective performance.

FAQ

 

Q: How does AVR work in a generator?

A: An AVR works by constantly sensing the generator's output voltage and comparing it to a preset reference value. If there's a deviation, the AVR automatically adjusts the exciter field current, which changes the magnetic field strength within the generator. This action either increases or decreases the voltage to maintain a stable output, ensuring the power is consistent regardless of changing loads.

Q: How to choose AVR wattage?

A: For appliances that utilize a motor (such as a refrigerator's compressor), the AVR rating should be at least three times the rated wattage of the fridge. This is to account for the surge in power that occurs when the compressor is turned on.

Q: How do I choose an AVR for my generator?

A: Choosing your AVR depends on the type of generator you have. It is also dependent on your generator's size. As such, our AVRs are ideal for all sized and type of generator. We can provide the 2 KW and 5 KW AVR for smaller applications like lighting within a building.

Q: Can a generator run without an AVR?

A: Generators that operate without an AVR can produce inconsistent power, leading to flickering lights, irregular performance of machines, and possible damage to sensitive electronics.

Q: How do I adjust the AVR on my generator?

A: To adjust a generator's AVR, you must first safely access the Automatic Voltage Regulator by removing a side or end cover, then locating the small voltage adjustment screw. With the generator running outdoors at the correct speed and load, use a flathead screwdriver to slowly turn the adjustment screw to achieve the desired output voltage, monitoring with a voltmeter. Turn clockwise to increase voltage and counter-clockwise to decrease it.

Q: What happens when a generator AVR fails?

A: When a generator's Automatic Voltage Regulator (AVR) fails, the generator loses excitation, leading to unstable or no voltage output, causing the generator to shut down on an under-voltage fault or run with erratic power, potentially damaging attached equipment. Symptoms include fluctuating voltage, inconsistent power, system resets, and a visible physical failure of the AVR itself. Immediate replacement of the AVR is recommended to prevent further damage to the generator.
