-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.
* Load is the place where the electric energy is consumed by the electricity system. Electric load is very diverse, can be a city, a factory, .. With the huge number and variety of loads, the number and types of incidents that can occur in the load is also numerous and corresponding complexity. Understanding this, GE has come up with comprehensive solutions for load protection issues:
- Protection of loads: GE has a wide range of products suitable for a wide variety of loads
Monitor and show important parameters of the load: GE's relays can monitor and display important parameters of the load such as U, V, f, ...
- Integrating multiple protection functions GE relays have built-in protection functions to better serve customer requirements as well as make the system more secure. In addition, GE successfully developed new load management technology, helping the load to operate more efficiently and safely.
- 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.
- 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
