Product details
Detailed information on the Italian DOSSENA earth leakage relay:
Italian DOSSENA earth leakage relay
Advantages:
1，Reliable, secure, and technologically advanced. Obtained ISO9001:2000 certification since 1996, and all products have EU CE certification. Since its establishment in 1962 until today, DOSSENA has always been committed to the high quality and professional technology of its products to ensure full satisfaction of user needs.
2，The DER3 series grounding differential relay is designed to comply with the IEC60947-2 standard, which requires manufacturers of grounding differential protection relays to perform a series of strict tests. Differential protection plays a crucial role in today's power system, and these standards are essential to meet the needs of factory safety and industrial production continuity.
3，Due to its high level of anti-interference performance, the DER3 series relays can overcome strong interference problems and provide strict protection for power industry systems.
4，DOSSENA continues to ensure transparency and clarity in its quality process, and has entrusted the testing of DER3 series products to qualified certification agencies for certification. Therefore, DOSSENA products represent safety, reliability, and full compliance with mandatory quality standards. The cooperation with world-renowned institutions ensures the excellent quality of the DER3 series.
5，DOSSENA products take customer satisfaction as their responsibility. The new generation DER3 series adopts technology that is easy to use, very reliable, easy to set up, and has excellent performance, thus gaining high recognition from users. One important consideration in the development of DER3 grounding differential protection relay is humanization.
6，DOSSENA provides various forms and specifications of grounding differential relays and matching transformers, with rich performance and multiple choices for users.
If differential pressure protection equipment can be used correctly, it can ensure the safety of goods, circuits, and circuit boards.
The DER3 series grounding differential protection relay can adjust the threshold current dispersion (up to 5A) and relay interruption threshold (up to 5 seconds) over a wide range, providing a variety of different differential protections.
The DER3 series grounding differential protection relay, combined with the newly developed "D" series transformer (which can choose open-loop or closed-loop), ensures high safety in factory production. And fully comply with the following requirements of international standards
-Not sensitive to current distortion;
-Strong anti-interference ability;
-Accurate measurement of current dispersion;
-Reduce unnecessary tripping;
-Free from interference from harmonic currents, grounding currents, transitional and functional currents
-Electromagnetic compatibility.
These good anti-interference levels represent the highest level of safety, thus potentially avoiding the risk of accidental tripping.
According to the requirements, each differential relay should be regularly inspected to ensure the good operation of the differential protection link.
In order to optimize operations, DOSSENA recommends using the new data logger MuItiLog to plan for automatic periodic checks and data storage.
Due to the high contrast display screen of the DER3 series grounding differential protection relay, the parameter display is simple and intuitive. And the display screen can also show the operating status of the instrument through different colors. For example, green (alarm), light blue (set), red (intervention).
The DER3 series of grounding differential protection relays with different specifications developed by DOSSENA have a wide range of functions and can basically meet all needs. The advanced DER3/2 series also comes with RS232 or RS485 communication.
For differential protection facilities, users value the automatic testing of the circuit breaker coil more than just being able to use it. This is also the driving force and foundation for DOSSENA to invest in research and development.
The auxiliary voltage selection range of the DER3 series grounding differential relay is wide, from 48AC to 400AC, from 24DC to 240DC, and different specifications of transformers are also used in conjunction.
Choosing DOSSENA's DER3 grounding differential relay means choosing a safe product with excellent performance, high quality, and compliance with existing standards.
