Temperature and Partial Discharge Monitoring Systems
Product Overview
Each day, the electrical standards become more rigorous in order to ensure the continuity of production processes and especially human safety and security. Power Technologies created the selfpowered energy harvesting sensor, which aims to monitor and protect electrical assets, acting in a predictive was and as an early detection potential problems that could lead to catastrophic incident.
The line is composed been monitoring and protected systems based on network of SMART IoT sensors, able to perform temperatures and humidity measurements, warranting the security of user and public safety. These sensors was specially design to provide completed integral monitoring solutions fof high-voltage and low-voltage distribution network including distribution room, switching station and user distribution room and etc, which demand high number of sensors, dispose of short space with low cost, ensuring space saving without damaging insulation the sensor is used to monitor dynamic and static contact connection of disconnector, the cable outlet, the cable connector, the transformer inlet and outlet and other key parts that are easy to cause heat due to poor contact and aging.

Product Overview
The characteristics, functions and some precautions of PTSPD4000W wireless five-in-one partial discharge sensor, and to provide technical and usage reference to the user of the wireless PTSPD4000W. In view of the partial discharge phenomenon caused by material aging, poor contact, current overload and other factors, and the hidden dangers of failure that should not be detected, the PTSPD4000W sensor, which can work steadily in the state of live operation of the equipment and in high and low temperature environment, has the advantages of small size, light weight, wide range of applications and strong adaptability. Its greatest advantages using ultra-high frequency, ultrasonic, transient ground wave three-in-one monitoring technology temperature and humidity two-in-one technology fusion, wireless five-in-one temperature and humidity sensor is compatible with external power supply and battery power function, solve the long-term power supply problem of sensors, and the use of microelectronics technology, sensor low-power technology, sensor life is greater than 10 years, product safety and reliability, easy to deploy, maintenance-free. Powered batteries are industrial batteries with very low static losses and are non-rechargeable for at least 2-3 years of service.
PTSPS068 Wireless Temperature and Humidity Sensor
Product Overview
The PTSenR PTSPS068 Wireless Temperature and Humidity Sensor is developed by our PT for the locations requiring realtime temperature and humidity report, such as electrical cabinet, electrical box, monitoring room, stockroom, transformer, storage area, data center, busduct, switchgear and etc. The PTSenR solves many issues, including high wiring cost, difficult wiring, inspection need and etc. With the sensor, current temperature and humidity can be transmitted
through SUB-G wireless communication to monitoring terminal or background for checking at any time. PTSPS068 adopts design of ultra-low power Zigbee Green
Protocol design, RF communication and data verification technologies. Its advantages include easy installation, strong anti-interference ability and reliable performance. It can transmit collected real-time temperature and humidity data through radio waves to the host, and achieve uninterrupted and accurate measurement in this way.
