Currently, THT is the official distributor of GE protective relay products in Vietnam market. The electrical system in Vietnam uses a lot of GE relays provided by THT. All of them work stably and receive high performance ratings from the users.
* The generator is considered the heart of the electrical system because it is a device that generates electrical energy from other energy sources. Therefore, keeping the transmitter operating safely and continuously is an indispensable requirement to help the system operate stably as well as bring maximum benefits to the investor. Understanding this need, combined with its engine manufacturing experience -GE is the largest engine manufacturer in the world, GE's generator protection relays provide the best technology for protection. Generator comes to customers. The outstanding advantages include:
- Diversified protection subjects: GE has a wide range of products suitable for many power levels of transmitters
- Excellent quality: Designed and produced by the talented hands of experienced engineers, GE products have outstanding quality and high perfection.
- Multifunctional protection relay: In addition to the main protection functions, GE's generator protection relays also incorporate additional protection functions such as 24, 25, 32, ...
- Multi-relay relays: Integrating communications from the most popular to the most modern such as Modbus RTU / TCP-IP, IEC61850, ... GE relays can connect well with existing systems of factory.
- Exemplary design: With the standard 19 "Rack design, the GE relays are suitable for most existing electrical panel designs. In addition, the draw-out design series saves time. testing, installation and maintenance-upgrade time, believing that customers will be satisfied with GE's products.
- Works well with a variety of environmental conditions: With an IP54-rated body and standards for impact resistance, GE relays work well in a variety of difficult conditions smoothly. In addition, with the patented work environment monitoring system, GE relays show all necessary parameters of operating conditions and equipment conditions.
- In addition, when using GE products, customers also enjoy additional incentives:
+Designed, tested and fully assembled at GE facilities
+Guaranteed under GE's 10-year warranty
