A 100KVA AVR (Automatic Voltage Regulator) is a high-capacity voltage stabilizer designed to regulate fluctuating input voltage and provide a stable power supply to electrical and industrial equipment.

Question 13

What does 100KVA mean?

Accepted Answer

100KVA means the AVR has an apparent power capacity of 100 kilovolt-amperes. It is designed to handle electrical loads up to its rated capacity, subject to power factor and load characteristics.

Question 14

What is a 100KVA voltage stabilizer?

Accepted Answer

A 100KVA voltage stabilizer is an automatic voltage regulation system that corrects high, low, and fluctuating input voltage to provide a more stable output voltage.

Question 15

What is the price of a 100KVA AVR in Bangladesh?

Accepted Answer

The 100KVA AVR price in Bangladesh depends on the brand, input voltage range, output voltage, phase configuration, regulation accuracy, warranty, and installation requirements. Contact a supplier for the latest quotation.

Question 16

Can a 100KVA AVR be used for CNC machines?

Accepted Answer

Yes, a properly selected 100KVA AVR can be used with CNC and other precision machinery when its voltage, capacity, phase, frequency, and regulation requirements are compatible.

Question 17

Can a 100KVA AVR handle motor loads?

Accepted Answer

Yes, but motor starting current must be considered. Motors, pumps, compressors, and similar equipment can require significantly more current during startup, so the AVR must be correctly sized.

Question 18

Can a 100KVA AVR be used for pumps?

Accepted Answer

Yes. A 100KVA AVR can be suitable for compatible pump systems, provided the running load and starting current remain within the AVR's rated capacity.

Question 19

Can a 100KVA AVR work with a generator?

Accepted Answer

A 100KVA AVR may be used with a generator if the generator's voltage, frequency, capacity, and electrical characteristics are compatible with the AVR.

Question 20

How much load can a 100KVA AVR handle?

Accepted Answer

A 100KVA AVR has a rated apparent power capacity of 100 kVA. The actual usable power depends on the load's power factor, starting requirements, and the AVR manufacturer's specifications.

Question 21

How do I calculate the required capacity of an AVR?

Accepted Answer

Calculate the total running load of all equipment that will operate through the AVR and consider starting or surge current. Additional capacity may be required for motors and future expansion.

Question 22

What are the benefits of a 100KVA AVR?
