About Me

Electrical engineer & Solar System designer

My name is Jürgen Tjiratjiza Viakondo, I am a high achiever and self-starter who earned a B.Sc. in Electrical Engineering (Honours) and has a talent for designing transmission and distribution systems, solar systems, power systems protection, and low- and medium and voltage systems. I am capable of using engineering programs like Revit, AutoCAD, Proteus, MATLAB (Simulink), and ETAP. Flexible, a fantastic team player, and quick to learn new skills in any workplace. I've gained experience in electrical engineering while working as an intern at NORED, where I helped to expand many low- and medium-voltage networks and diagnose malfunctioning transformers and other electrical equipment. Because of this experience, I made the decision to concentrate my design project on a challenge that the business faced. I created a GSM-based remote monitoring system for distribution transformers since NORED had a high risk of premature transformer failure due to improper operating circumstances.

EDUCATION AND TRAINING

I have a B.Sc. in Electrical Engineering (Honors). During my studies, I learned how to design transmission and distribution systems, solar systems, power system protection, low medium and high voltage systems, among other things. Engineering software like Revit, AutoCAD, Proteus, MATLAB (Simulink), and ETAP are all things I'm competent of using.

EXPERIENCE

I worked as an electrical engineering intern at the NORED Ongwediva branch in 2021. My duties included maintaining and updating the electrical network, carrying several field engineering tests on electrical equipment like transformers and reclosers, and conducting cost analysis for ongoing projects.

Removal of Aerial Bundled Conductor

On this particular day, we were installing an outdated meter box for a client and switching their connection from an overhead (ABC cable) connection to an underground connection.

Routine fuse link replacement

Several fuses blew during the wet season and had to be replaced. For safety reasons, we had to check the other fuses at that junction when one of them burned out and replace them as necessary.

Replacement of a 100KVA transformer pole

Two 3 phase distribution transformers poles were to be replaced in order to prevent pole from breaking and the transformer falling as the wooden poles were rotting. The following were steps taken in the transformer poles replacements

Routine street light replacement

Street lights have to be investigated as part of electrical network maintenance, repaired, or replaced as necessary.

Troubleshooting of a SWER Recloser

We had to determine the cause of a three-phase Recloser that was connected to a SWER line that unexpectedly tripped. The team had to use the sectionalizing method for troubleshooting in order to determine whether the transmission line was short circuited. However, with the help of the senior engineers, the line was clear and no issues were found. Since it was determined that the earth fault and phase imbalance testers were what was tripping the system, they were turned off.

New transmission line and transformer connection

A new 33kV three phase Line was set up in a remote village as part of the expansion of the electrical network. A three phase 33kV/400V Delta Star transformer was used as its connection. This is necessary because it will bring electricity to isolated areas.

Star delta motor starter troubleshooting

I helped Kwanavare Electric debug an customer star delta motor starter that was unable to transition from the starting mode to the operating mode and an incoming load line voltage of 290V. The issue was brought on by a faulty line pin insulator and an inappropriate timer circuit connection.

Tender capturing

I helped with the capturing of a new network connection tender during the attachment at the Ondangwa branch. The project manager was required to evaluate the cost of the project from multiple electric companies/tenders prior to the commencement of construction, identifying which firm was the least expensive and had all essential tools to do the job. I utilized Microsoft Excel to record information about the tender.

Replacement of a 200KVA transformer pole

New Connections and system upgrade

New connections were the most frequently done task, and I was in charge of connecting the wire to the Ready-Board and Prepaid meter as well as to the power supply, which can be a kiosk or pole mounting box. Additionally, we rewire outdated kiosk boxes that require maintenance.

Three phase transformer testing

During the Internship, several 3 phase transformers were being investigated since they were causing failure in their electrical networks. The tested transformer was grounded and disconnected from the network. A TESTRAND 400 connected to the transformer and the engineers' computer was used to test the following parameters: Short circuit test, HV and LV winding resistance, Demagnetizing and Turns Ratio test.

Underground cable fault location

During my internship, there were a number of no power claims that were brought about by issues with the underground lines. Short circuit line to ground faults, which affect all lines, were the most frequent type of short circuit defect in cables. We used the method of was used Sectionalizing as the thumper machine was inaccessible
