Hi Mr. Srinivas;

 

Thank you for your input and advice. I personally think that the energy saving obtained is not as quantifiable as reducing the motor rpm. For pump and fan application (variable torque), reducing the speed meand reduced kW definitely.

 

I think after reading this forum, I will leave the idea of energy saving using AHF.

 

On the other hand, Mr. Srinivas, how can we “quantify” the effect of harmonics in our system for the case of breaker trip, motor wear and tear, and so on? This kind of losses cannot be proven with real demonstration. They only happen “occasionally”.

 

Or is there a way to trip a breaker by increasing the harmonics?

 

Your email will be highly appreciated, Mr. Srinivas.

 

Regards,

 

Rudy

Hi Mr. Srinivas;

 

Can I have your opinion, please? Most of my customers only care about the energy saving that may result from installing AHF. If I talk about the heat loss, etc etc, they are not buying it because their plant is “so far so good”.

 

Recently I found that Fluke 425 series II come out with new feature where there is kWh saving potential due to harmonics. Do you have any concrete calculation/argument that energy saving is indeed obtained via AHF installation?

 

Thanks,

 

Rudy
