Hydroelectric power plants safety is ensured
Flooding risks are usually caused by poor planning, unpredictable natural events, equipment failure
Since its inception, hydropower has been appreciated as a clean, reliable and sustainable source of energy and continues to deliver with nearly a quarter of worldwide energy being produced by water. One of the overriding advantages is that hydroelectric power plants can be used for storing electric energy. However, there are many concerns with large dam facilities: significant impacts on the regional ecosystem, disrupting habitats, and fatal consequences even if accidents are rare.
is the lifespan of hydroelectric plants.
Hydropower is the largest contributor of all renewable energy sources. It is abundant, low cost source of power (where applicable), despite high upfront building costs.
All hydroelectric power stations face environmental and technical challenges. Regardless of where the plant is geographically located, the room housing the machine has to deal with high relative humidity, moisture, and water that can be acidic and may contain bacteria, sand and/ or debris. Our network of engineering, sales and service staff has profound know-how on power production under every conceivable condition. This knowledge serves to deliver the appropriate answer to your environment.

Main critical applications
Bearings in the turbine, generators and shafts
Temperature measurement is essential to ensure that the plant works properly. Any hot point in the bearings must be identified so that appropriate action can be taken to prevent heat loss through friction, wear and tear or possible equipment destruction. How do you cope with such application? Have you heard about our iTHERM® StrongSens RTD sensor technology?
Unsurpassed vibration resistance (> 60g) for ultimate plant safety
Decrease of maintenance and downtimes
Speed and break control system
Measuring level in the pressurized air-oil tank avoids any over speed in the turbine that could damage the whole power station. The level can be achieved either by using differential pressure transmitters or by using a guided wave radar mounted directly in the tank or in a bypass chamber solution. It is critical to clean the oil and identify leaks to ensure proper functioning of the system. How do you monitor the oil pressure?
Reliable pressure transmitters that can withstand upwards of 600 psig
Hermetically sealed Contite measuring cell with condensate-resistance for our Deltapilot product range
Safe and reliable function regardless of tank geometry for our Liquicap product range
High voltage areas as conduction bars, thyristor bridges
High ambient temperatures in high voltage areas are dangerous and therefore must be monitored continuously. Fire detectors should be provided as a safety precaution. The ambient temperature sensor Omnigrad has been designed specially for this purpose, and can include a temperature transmitter assembled in the head.
Types of protection for use in hazardous locations: Intrinsic safety (Ex ia) and non-sparking (Ex nA)
High flexibility through user-specific insertion lengths and variable process connections
Failure of the level measurement that controls the drainage pumps can indicate an increase of the water level and an eventual flooding of the station. Therefore water-level, flood and evacuation alarms are an absolute necessity. It is common to use floats or conductivity level measurements but these can fail due to high humidity and corrosive. A good alternative are ultrasonic or hydrostatic level devices such as the Waterpilot.

Flood protection schemes can be implemented to automatically close intake gates or hilltop valves and keep turbines operating
The main purpose of a surge tank is to control pressure variations due to rapid changes in the velocity of water. It may be desirable to operate at the tank's level limits to keep the product concentration and quality constant or enable the product formation rate to continue to meet production rate requirements. This implies that greater demands are put on the level measurement accuracy. We have the experts who can advise you the best fit solution for your crucial checkpoints.
