Three-phase
Our commitment to excellence is rooted in a deep understanding of the challenges faced by those who rely on our relay testing units day in and day out. We value the input of the dedicated professionals who work with our equipment regularly, and it shows in the design of our units. Each unit is meticulously crafted to be rugged, capable of withstanding the rigors of real-world testing environments. Portability is a key feature, ensuring that our equipment can be easily transported to wherever it’s needed, facilitating efficient fieldwork. Moreover, we’ve prioritized user-friendliness, making operation straightforward and intuitive. Our relentless pursuit of user feedback guarantees that every relay testing experience is seamless and productive, empowering you to focus on what truly matters – ensuring the reliability and performance of critical protection systems.
Our range of three-phase relay testing units offers unparalleled versatility and reliability, catering to the various stages of the grid, from generation and interconnection to transmission, distribution, and motor protection.
Within this range, you’ll find units equipped with current or voltage sources, or combination of both, that can be seamlessly reversed. This flexibility empowers you to perform comprehensive relay testing with ease, ensuring the robustness of your protection systems.
Efficient testing means simulation of a complicated protection scheme, and for this it’s often necessary to have multiple outputs. That’s why our three-phase testers are available in configurations that provide up to 12 high power outputs within a single set. This high-output capacity streamlines complex testing procedures, saving you time and effort.
We understand the importance of seamless integration within the IEC 61850 standard, a cornerstone of modern substation communication. Our relay testing units like Quasar are designed with native support for IEC 61850, enabling easy and efficient testing within this standardized framework. This support ensures that your relay testing procedures align with contemporary grid communication standards, simplifying the testing process and enhancing overall efficiency.
For precise and realistic testing scenarios COMTRADE playback functionality is a must. This feature allows you to replay real-world fault and disturbance records, providing a highly accurate and controlled environment for testing. COMTRADE playback ensures that your protection systems are rigorously evaluated under a variety of conditions, helping to guarantee their effectiveness in critical situations.

Advantages of testing 3 phase relays
-
Equipment Protection: By detecting incorrect phase sequence, three-phase relays help prevent potential damage to motors, pumps, generators, and other sensitive equipment.
-
Reduced Downtime: By preventing equipment damage, three-phase relays contribute to minimizing downtime and maintenance costs.
-
Reliable Monitoring: The reliable and continuous monitoring of three-phase networks guarantees the trouble-free and cost-effective operation of machines and installations.
-
Flexibility and Control: Three-phase monitoring relays offer maximum flexibility and control, with rated voltage levels up to 820 V AC and 400 Hz.
-
Safety: They increase the safety of the electrical circuit by avoiding the risk of electric shock or fire due to the short circuit of the motor windings.
-
Motor Protection: Motors are sensitive to incorrect phase sequence, which can cause them to run in the reverse direction or generate excessive heat, leading to damage.
-
Pump Control: In pumping systems, three-phase relays prevent the pump from running in the reverse direction due to incorrect phase sequence, avoiding issues like cavitation and reduced efficiency.
-
Generator Synchronization: In power generation plants, three-phase relays ensure that generators are synchronized with the correct phase sequence, preventing out-of-phase paralleling and subsequent equipment damage.
Keep in mind these advantages my vary depending on different factors.
