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…
SCP – Signal Conditioner Membrane/Bag Monitor
The transformer or power reactor sealing system uses a rubber membrane or bag in conservator expansion tanks to prevent the insulating oil from making contact with outside air. The bagprevents oxygen and humidity contamination, both of which accelerate paper degradation. The bag system also retards oil and dielectric breakdown. However, membrane or bag leakage may…
IDX – Intelligent Electronic Device 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 – IDX ensuresfailure reductions through early detection and diagnosis of equipment defects hence maintaining continuity of the…
IDM – Intelligent Electronic Device OLTC Torque Monitor
Because it has moving parts, which switch high voltages and currents, the on-load tap changer (OLTC) is statistically a major source of faults in transformers. In order to detect defects in the OLTC at an early stage and reduce the likelihood of unexpected downtime, the IDM monitors the OLTC torque online, alerting the operator to…
IDR – Intelligent Electronic Device Voltage Regulator Monitor
In an increasingly demanding marketfor Quality of Supply, the rules for acceptable supply limits are becoming more stringent. There is a growing need for tools capable of meeting this reality and ensuringhigh levels of voltage regulation. Treetech’s New Voltage Regulator Monitor IDR offers a solution that goes beyondthe traditional and well-known single phase and three…
