SDT – Smart Device Expert Oil and Winding Temperatures Monitor
Electronic thermal monitoring for equipment such as transformers, motors, generators and other applications is essential for the safe operation of these systems. This facilitates maximum return on the investment from these assets without jeopardizing their service life. The Smart Device SDT by Treetech is a complete solution for monitoring temperatures of oil and winding temperature…
SDV – Smart Device Expert Voltage Regulation and On Load TAP Changer Monitor
Treetech’s innovation over many years has perfected voltage regulation. The SDV Smart Device goes far beyond a traditional voltage regulator because it allows intelligent voltage regulation that is optimized through Artificial Intelligence techniques that use load curves, thereby producing better energy quality and fewer losses. The On Load Tap Charger’s maintenance management functions also optimize…
SDX – Smart Device Expert Circuit-breaker Monitor
Circuit breakers are widely employed to protect and switch electric power systems. Therefore, they must be in perfect operating condition in order to maintain system reliability and safe installations. Online monitoring and condition assessment using the expert Circuit-breaker Monitor – SDX ensures failure reductions through early detection and diagnosis of equipment defects hence maintaining continuity…
SDB – Smart Device Expert Bushing, CT and PT Monitor
Condenser bushings are subject to stress due to transient over voltages like surges and atmospheric discharges. Combined with the fact that they are impossible to test when the equipment is energised, they are one of the main areas of failure in transformers and reactors. Heavy fines are imposed when the equipment is unavailable during off-line…
SDG – Smart Device Expert Gas and Moisture Monitor
Detecting the presence and evolution of gases dissolved in the insulating oil of high voltage equipment like power transformers and reactors is a proven and efficient tool for diagnosing their internal condition. Measuring these gases in the laboratory through gas-chromatography tests in samples of oil taken periodically(months/years) from the equipment can eventuate in the possibility…
SDS – Smart Device Expert Disconnector Monitor
Motorized disconnecting switches are used in great quantities insubstations for equipment insulation and operation. The reliability of the electrical system and the safety of installations depend on switches remaining in good condition and closure and opening operations occurring correctly, especially when remotely controlled. To achieve this, the SDS Expert Disconnector Monitor performs an online status…
SC – Signal Conditioner Digital Transducer
Digitalizes values of temperature, tap position, current, voltage and contacts by generating serial outputs (DNP3.0/Modbus) plus analog and contact communication. Digitalizes alarm/trip contact status from intelligent SCA High-Speed Relay outputs. Transducers are applied in substations and high voltage and industrial plants to convert signals of different nature – like temperature, AC or DC voltage, AC…
SCA – Signal Conditioner Intelligent High-speed Relay
High speed auxiliary relays are used in substations and high voltage and industrial plants to multiply alarm or tripping contacts with minimum delay. The 4-output contacts of the SCA Intelligent High-Speed Relayfulfils this function (two versions of the relay are available) with pick-up times below 2.5ms: Simple implementation: one voltage input to control the 4…
SCL – Signal Conditioner Circuit-breaker Coil Monitor
One of the highest failurs found in high and medium voltage circuit-breakers is that drive coils open or burn – there is one coil to close and two coils to open the circuit-breaker. To detect a failure, the SCL has inputs for monitoring the electrical continuity of up to 3 coils simultaneously, with independent alarm…
