Enhanced Data Analysis and Patented Techimp T-F map filter technology

The fundamental innovation of Techimp PD diagnostic systems consist of the acquisition and processing philosophy. Techimp’s acquisition units are provided with ultra-wide bandwidth acquisition system, which collect PD pulse peak, PD phase and PD pulse waveforms. Per each acquired pulse the acquisition unit automatically calculates its equivalent time and equivalent frequency content, building the so called “T-F map”. The map shows groups of pulses “clusters” characterised by same time and frequency content, i.e. homogenous pulses.

An efficient separation of different discharge activities, including noise rejection, can be achieved through pulse shape analysis. It avoids identification to be affected by different phenomena overlapping, as well as noise superposition to real PD phenomena.


Techimp offers diagnostic condition assessment services for all electrical MV/HV assets. Customers around the globe benefit from the broad experience of the Techimp service team. Besides ON-line and OFF-line PD spot testing, our engineers perform condition assessment by measurements such as PI (polarisation index), Tan-D, TDR (Time Domain Reflectometry) and insulation resistance. After each test and inspection performed, customers receive a comprehensive test report as a basis for further asset management decisions.

The Techimp brand is known for excellence in the field of innovative diagnostic technologies which are applied to electrical engineering. More than 15 years of research and field experience has resulted in a complete portfolio of products and services, providing customers

and partners with the best knowledge based solutions for all electrical assets and smart grid technology.
