Case study

Disruption of production activities 64% of production interruptions are caused by fires and explosions The first cause comes from problems with electrical equipment, In particular, lack of maintenance is the cause of the majority of all electrical incidents (77%)

Explostion site of 500KV substation in Da NangExplosion site of 110KV substation in Thai Nguyen On September 2, although the load of most manufacturing industries was low due to the national holiday, and was mainly household load, an incident that the electricity industry considered "force majeure” still occurred at the 500kV Da Nang station. This serious incident disrupted the connection between the 500kV North-South power system, causing 35 provinces and cities across the country to lose power for more than an hour. It is worth mentioning that serious incidents occurred continuously on the...

Wireless Temperature Sensor

False or incorrect alerts due to sensor interference; Short transmission distance; Small size; Long service life; Long transmission distance Free maintenance with self-harvested type. High voltage High accuracy and stability. High cost Hard for installation ; Require maintenance; Cabling work;

Extremely powerful and robust - withstand up to 500kV AC, 1500kV of lightning impulse - operated in the harshest environments (next to ocean and affected by foehn wind)

Wireless temperature sensor What about locations without self-harvesting supply? Super low power technology - 3 years, 5 years (optional) - Temperature of test object - Battery level

Data collector MQTT, Modbus

Data collector Slave Slave MESH NETWORK The locations without wifi? Slave Does each data collector have to use 1 data sim?

Transmission distance Slave Slave 3 metal covers 2m

Thermal Camera
