2019-10-12

Hydroelectric power plant (hydropower station) is a complex system. A large number of temperature measurement points need to be controlled and monitored so as to ensure the long-term stable operation of the unit, avoid unexpected shutdown due to sensor failure, optimize the maintenance period and ensure the service life of the generator set.
 
 
Temperature measurement of hydropower station
——————————————————————————————————————————————————————
As a part of the monitoring system, the temperature measurement system of hydropower station, which integrates measurement, processing, analysis, alarm and protection functions of the equipment temperature, plays an important role in the automation system of hydropower station. Stable, reliable and accurate temperature measurement system is the basis of safe and stable operation of the power station. The core temperature measurement of the stator winding of the water turbine is aimed at the temperature measurement of the winding of the large and medium-sized hydro-generator. The special winding stator temperature sensor is used to monitor the temperature of the stator winding of the hydro-generator set of the hydropower station. Thrust and guide bearing pad temperature measurement and bearing pad temperature are directly related to the safe operation of water turbine unit. It is of great importance. The monitoring of bearing pad temperature must be accurate and reliable. The temperature measurement of the cooling system of the hydropower station requires the cooling of bearing system, stator and rotor winding and iron core during the operation of the water turbine unit. The temperature monitoring of the inlet and outlet of the cooling system can reflect the operation of the cooling system and the generator unit and ensure the safe operation of the unit.
 
 
Industry leading
——————————————————————————————————————————————————————
Testeck has the highest market share in the field of water and electricity temperature measurement. It has provided maintenance and transformation of temperature monitoring system for more than 800 hydropower stations and 2,400 hydro-generators in China. 85% of power stations above 1 million kilowatts use Testeck’s temperature sensors. Enduring: Testeck has been serving China’s hydropower industry for many years. Our sensors have been working under the worst conditions such as immersion, impact and electromagnetic interference, but these have never affected the stability of our products. Being durable and reliable is our biggest advantage, and each sensor can work stably for more than 8 years. Concentration and professionalism: We monitor every detail of the hydropower station: thrust, guide bearing, oil groove, air cooler, main transformer, stator winding and stator core. The designed sensors have different features: oil resistance, temperature resistance, root disconnection prevention, oil anti-seepage and easy installation, ensuring the excellent completion of every detail of the monitoring task. Excellent service: Testeck has good R&D team, excellent engineer team who can make timely and excellent response. We are tailor-made for each hydropower plant, and each product is tempered to meet your requirements.
