Testing the acoustical noise of a generator set and interpreting the data

Large generator sets produce high levels of noise that must often be mitigated to meet national regulations and directives. This usually involves key decisions about the optimal generator set location and installation, how to design noise control systems and other factors, which is why it is important to conduct accurate noise level assessments timeously, before […]

Condition-based assessment of on-load tap changers

On-load tap changers (OLTCs) are a crucial element of utility networks, as they must operate in a precise fashion in order to maintain a constant voltage output. This must be achieved regardless of variation on input or load. OLTCs have been a weak link in many networks, as they deteriorate over time due to mechanical […]
