Syncronized PMUs

Syncronized CoDiS PMUs

January 2020

We are connecting two of our 18 channel CoDiS PMUs enhanced with synchronization hardware for measurements on two locations separated by more than 100m.

This synchronized and easily expandable setup enables us to simultaneously measure 36+ channels, while retaining portability and all of the advanced features of CoDiS.

Dynamic Behaviour of Hydro Units in the RZL - Hydro2019 conference

October 2019

VESKi's CEO Ozren Oreskovic presented paper with case studies on Hydro 2019 conference. The paper "Dynamic Behaviour of Hydro Units in the Rough Load Zone" was written by Ozren Husnjak, Ozren Orešković and Franjo Tonković. The paper deals with issues on Francis turbine hydro units during Rough Load Zone operation (RLZ). By using CoDiS online monitoring system, data was collected continuously throughout machine operation and through several different case studies. The result is a conclusion that the hydrodynamic pressure pulsations are often the consequence of vibrations, not their cause.

CODIS PMU - portable vibration monitoring unit is again in action

CODIS PMU - portable vibration monitoring unit is again in action

September 2019

Veski CoDiS-PMU (Portable Monitoring Unit) 16 channel device is again in action!

This time we measured vibrations, air gap and magnetic field on a 30 MW Francis unit. The unit suffered from pronounced magnetic unbalance. The PMU worked together with CoDiS-PDS (Portable Diagnostic System) software as a valuable diagnostic tool to help detect and correct rotor geometry issues. Our goal was to obtain an answer to the question about what should be done during the unit's overhaul.

At VESKi Monitoring Academy you will learn how to turn data into insights

June 2019

Last week we held VESKi Monitoring Academy training at the largest HPP in Croatia. Training included theoretical and practical training on machine condition monitoring , data interpretation and diagnostics.

Training also included connecting our fully modular and portable CoDiS PMU (Portable Monitoring Unit) to a 3rd party equipment installed at the plant. Data gathered by the CoDiS PMU was later analysed by the plant's engineers during hands-on session.

Successful CoDiS training in Tasmania

Successful 5-day CoDiS training at Hydro Tasmania

May 2019

VESKi Experts held a 5-day course on CoDiS Portable Monitoring Unit (hardware) and CoDiS Portable Diagnostics System (software) for engineers of Hydro Tasmania.

After delivery of two CoDiS Portable Monitoring Units earlier this month, VESKi organised three days hands-on measurement training, and a two days theoretical and analytical course on vibration and air gap measurements analysis.

Hydro Tasmania engineers are now trained to use CodiS PMU, a perfect solution for periodic shaft and bearing vibration monitoring on generators and motors.

VESKi experts taking part in unit overhaul

May 2019

During the major recent unit overhaul VESKi experts partook in disassembly and re-assembly of CoDiS monitoring system sensors. This included proximity probes, accelerometers and various additional sensors to cover critical machine components.

Beside typical vibration measurement probes, system was additionally customised for end user to include concrete forces measurements in the upper guide bracket region and lower bracket thermal expansion measurements.

The pump storage plant located in the EU generates 185 megawatts (248,000 hp) when producing electricity and uses 180 megawatts (240,000 hp) when pumping water.
