Question 1

What is a generator and what are the different types available?

Accepted Answer

Generators convert energy from a source into electrical energy through rotational mechanics. They transform one form of energy into another. There are three main categories of generators: 1. Portable Generators 2. Standby Generators 3. Inverter Generators. Common types include: 1. Diesel Generators 2. Emulsified Diesel 3. Gasoline Generators 4. Propane Gas or Vapor Generators 5. Natural Gas Generators 6. Biodiesel Generators 7. Hydrogen Generators.

Question 2

How efficient are Diesel Gensets?

Accepted Answer

Diesel is less flammable than all other fuel sources available hence diesel gensets are affordable to operate. Diesel generators perform very well for a long duration with proper maintenance. It also has a long lifespan.

Question 3

What do you mean by a kVA in a generator?

Accepted Answer

kVA or Kilovolt ampere is an apparent power of a generator. One kVA is equal to 1000 volt-amps. The higher the kVA rating, the higher amount of power a generator can make.

Question 4

What kVA rating should I choose for different types of generators?

Accepted Answer

Generators come in various sizes and power ratings, ranging from 6kVA to 500kVA. For commercial use, gensets typically fall within the 20-100kVA range. It's important to assess your power needs to select the appropriate kVA rating for optimal performance.

Question 5

What is the range of kVA required for a residential generator?

Accepted Answer

On an average, a home requires a 3-5 kVA generator to operate light and heavy electrical appliances.

Question 6

Why are generators rated in kVA and not kw?

Accepted Answer

Generators deliver active and reactive powers that depend upon power factors of the connected load. Kilowatts is power generated that is actually useful. As a generator produces both active and reactive power it is rated in volt-amperes (VA) and not watts (W).

Question 7

What are the various parts of a generator?

Accepted Answer

All generators have these 6 common parts: an engine, a fuel system, an alternator, cooling, lubricating and exhaust system.

Question 8

How does a generator create electric flow?

Accepted Answer

1. A generator utilizes electromagnetic induction principle where it converts mechanical energy into electrical energy. 
2. In its conductor, a coil is placed between 2 horseshoe magnets and a rapid rotation of the conductor coil results in production of electrical energy. 
3. The conductor coil and soft core form an armature together which is connected to a motor which gets rotated when the generator is fueled. 
4. An electric flow is induced with rotation of the coil as it cuts the magnetic field between 2 magnetic poles.

Question 9

What are the key differences between AC and DC generators?

Accepted Answer

AC generators, also known as alternators, work on Faraday's law of electromagnetic induction. They come in two types: synchronous and induction generators, both of which are brushless. DC generators convert mechanical energy into electrical energy and are typically used in off-grid applications. AC generators are commonly used in power plants and for large-scale electricity distribution, while DC generators are often used in smaller, specialized applications such as battery charging and electroplating.

Question 10

Where are AC and DC generators used?

Accepted Answer

AC generators	 are used in sailboats, power plants, electric scooters and bicycles.

DC generators are used in drilling machines, milling machines, lathe machines, fans, blowers, machine tools and reciprocating and centrifugal pumps.

Question 11

What are standby generators and where are they used?

Accepted Answer

Standby generators are used during grid power failures. They provide backup power to essential services such as hospitals, hotels, and shops, ensuring operations continue without interruption during temporary power cuts.

Question 12

How can we ensure the longevity of our gensets?

Accepted Answer

To ensure the longevity of your gensets, regular maintenance is essential. This includes proper lubrication, maintaining the cooling and fuel systems, checking batteries, performing engine exercises, conducting operating inspections, checking the exhaust system, and regular cleaning.

Question 13

How often should we change the oil of a diesel generator?

Accepted Answer

Standard maintenance and oil change in Bigger diesel generators are required every 6 months or 500 hours. However the frequency may change due to size or model.

Question 14

What is the ideal battery level for gensets?

Accepted Answer

The battery should be fully charged and maintained between 40-100% at all times. Avoid low battery levels. Regularly check the specific gravity and electrolyte levels of the battery. For detailed maintenance guidelines, refer to our user manual or contact our support team.

Question 15

When should engine exercise be performed?

Accepted Answer

A routine check of the engine is required to ensure safe running. It must be done within 15-25 days in a month for 30 minutes.

Question 16

How often should a diesel generator coolant be changed?

Accepted Answer

Based on the size of your generator, coolant can be changed within 2 years.

Question 17

Can a motor act as a generator?

Accepted Answer

Motor and a generator are two sides of the same coin. A generator converts mechanical energy into electrical energy and the motor does exactly the opposite of that. Both work on the same electromagnetic induction method.

Question 18

Which type of generator is best for residential purposes?

Accepted Answer

Whole house generators i.e. Standby generators can power up your entire home including all appliances and HVAC systems. These generators can run on petrol or natural gas. Some latest generators even run on solar power.

Question 19

Which type of generator is best for industrial purposes?

Accepted Answer

Diesel, natural gas or heavy fuel oil generators are generally preferred by industries. Large portable generators are the best choice for construction companies because of their easy movability.

Question 20

Can two generators be connected to increase power output?

Accepted Answer

Yes, if the total power requirement exceeds the capacity of a single generator, you can connect two generators in parallel to double the power output. This method increases efficiency and productivity, ensuring a stable power supply for larger demands.
