TECHNICAL AND HUMAN CAPACITY THAT PROVIDES ABSOLUTE CONFIDENCE AND SECURITY
The electricity sector, at all its voltage levels, involves critical operations in all its stages. To guarantee the reliability of the systems and protect the investment in assets, it is necessary to monitor the electrical and dielectric conditions of the same at all times. This is possible through electrical tests and trials.
Que nuestros clientes participen activamente del proceso, es sin duda uno de nuestros pilares de la confianza
"Rieder is, without a doubt, one of the best in electrical tests nationwide"
We offer electrical acceptance and maintenance testing services, essential for the commissioning and monitoring of assets in high and extra high voltage substations, as well as medium voltage distribution centers, in accordance with current international regulations and the highest standards in reliability and security.
Our experience makes us the best on all types of assets such as power transformers, disconnectors, power switches, current and potential transformers, line reactors, distribution cells, modules, encapsulated line and bay, auxiliary service systems, both in AIS and GIS technology; as well as tests to earth mesh systems and soil resistivity. And all of this with tests successfully carried out in the main electrical substations in the country.
Confidence in our results is extremely important, so we bet on the best testing technology available to provide our clients with absolute security and confidence in the results of the reports. In addition to following a strict traceability control in obtaining the results, in line with our
ISO 9001 quality certification.
Our unit engineers are responsible for providing this high-quality service. They are committed and closely aligned with our high standards, using all their human potential and experience at the service of customers. Moreover, they are constantly trained to provide solutions that are at the forefront of the constant demands on testing.
Our clients actively participation in the process, is undoubtedly one of our pillars of trust. That is why we present updated and designed test protocols according to each requirement and exigency, prior to the execution of the tests, as well as reports with high details in the procedures and clear results. these results are also backed by management software, acquired directly from the measurement equipment that we use, and they provide absolute certainty in the execution of the tests and eliminate any errors in the data recording and in reports dispatch.
We take care of our assets as much as yours, to provide the most real results. That is why our measurement equipment passes exhaustive and rigid quality controls periodically, such as preventive maintenance and periodic calibrations, thus eliminating uncertainties in tests, and increasing to the maximum the reliability in the results.
TESTING ON POWER TRANSFORMERS AND LINE REACTORS
Through the successful execution of insulation resistance, tangent delta, transformation ratio, short-circuit impedance, excitation current, dynamic scan of tap-changers, SFRA tests, winding resistance and core demagnetization tests of power transformers in 500, 220, 66kV and its instrumentation transformers incorporated in works such as Villa Hayes and Ayolas, Central Hidroeléctrica Yacyreta, Villa Aurelia, Molino, Lambaré, Blue Tower, guaranteeing the electrical and physical integrity of the most important assets.
TESTS ON POWER SWITCHES AND DISCONNECTORS
We successfully carried out acceptance tests on 500kV and 220kV switches and disconnectors, in the Villa Hayes, Ayolas, Puerto Botánico substations, as well as 66kV assets in the Villa Aurelia and Molino, with circuit breaker tests as resistance of insulation, tangent delta, contact resistance, operating times and phase mismatch, motor consumption and contact stroke. In disconnectors the tests performed were insulation resistance and resistance of main and secondary contacts (PAT).
TESTS ON GIS GAS INSULATED MODULES
We carried out the successful commissioning of 220kV GIS line and bay modules in the Villa Aurelia and Molino substations, as well as a 23kV distribution cell bank in the Blue Tower, Molino and Villa Aurelia. The tests carried out were those of insulation and dielectric strength by applied voltage, with special emphasis on the tests of the transformation ratio, saturation curve and winding resistance in the instrumentation transformers incorporated into the modules.
INSTRUMENTATION TRANSFORMER TESTS
Through the successful execution of insulation resistance, tangent delta, transformation ratio, short-circuit impedance, excitation current, dynamic scan of tap-changers, SFRA tests, winding resistance and core demagnetization tests of power transformers in 500, 220, 66kV and its instrumentation transformers incorporated in works such as Villa Hayes and Ayolas, Central Hidroeléctrica Yacyreta, Villa Aurelia, Molino, Lambaré, Blue Tower, guaranteeing the electrical and physical integrity of the most important assets of these subsations.
EARTH MESH STRENGTH AND SOIL RESISTIVITY TESTS
The soil resistivity and earth mesh resistance tests, carried out successfully at the Molino and Villa Aurelia works, allowed the correct sizing of the mesh and its reliability once completed, guaranteeing compliance with the required measurement values for the client.
Likewise, the soil resistivity tests carried out in the new San Lorenzo substation will mark the north for the expansion of said mesh.
