The term IVR stands for the following words:
Intelligent Voltage Regulator
Do you know how the IVR generators work?
These generators are a type of AVR generators that intelligently perform voltage control operations.
The advantage of these generators is determined when using inductive loads.
When an inductive load (such as an electro-motor or pump) is connected to a generator, at the moment of switching on the load, a high transient current (called in-rush current) is being passed through the load. This will cause the required power to rise up to 5 times the regular power rating of the load, and in order to prevent the generating set from shutting down or damage, you have to calculate over capacity for your gen-set to overcome this in-rush transient requirement.
But when you have a generator with IVR, the generator intelligently lowers the voltage and prevents the consumed power from rushing up so high, and the gen-set will no longer shut down due to overload.
This advantage means that you no longer have to provide generators with much higher power capacity for your inductive loads, and you will not pay extra money to buy excess power capacity when you want to connect you inductive load to a generating set.
