Power Systems’ Diesel Generator Meets Noise and Budget Requirements

A Melbourne-based electrical contractor Stretch Electrics contracted Power Systems Australia to supply a 145 kVA diesel generator designed to meet two specific conditions.  

The noise level had to be 70 db(A) @ 1m and the diesel generator had to be supplied on a tight budget.  

According to Robert Zebick, Sales Engineer at PSA, building a canopy to meet the low noise requirements was an expensive proposition and would have blown the budget right out.  

PSA’s engineering team came up with the idea of using a standard mass produced generator and canopy as these systems were low cost with noise levels around 85 db(A) @ 1m.

To meet the specific noise level requirements of the client, the second stage of design involved building another enclosure, which fitted over the mass produced canopy, and met factors such as service access, air flows and noise.

PSA achieved the customer’s requirements within the tight budget and also exceeded the noise requirement by achieving 67 db(A) @ 1m, a full 3 db(A) below the specified requirement.

At no load, the noise level was down to a very low 61 db(A) @ 1m that one could barely hear the generator running, said Struan Evans, PSA’s engineering manager.
