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…
SIGMA – Forecast On-line Monitoring Sub-system Temperature Forecasting
One of the principal factors limiting the loading of power transformers is the maximum temperature rise of the equipment as a result of its loading and the ambient conditions. High operational temperatures, will accelerating the loss of insulation life and increase the risk of failures (also as a result of the risk of bubble formation)….
SIGMA – Specialist On-line Monitoring Sub-system Specialist System for Diagnostic and Prognostic
The SIGMA Monitoring Software is composed of independent and scalable modules called Sub-systems that allow users to build a monitoring system, according to their own specific needs. The Sub-systems are based on mathematical models that execute the processing of measurements obtained from equipment sensors, transforming the raw data into useful maintenance information. As a result,…
SIGMA-Simulation On-Line Monitoring Sub-System Temperature Forecasting Simulation
One of the principal factors limiting the loading of power transformers is the temperature attained by the equipment, as a result of its loading and the ambient conditions. High operational temperatures, while accelerating the loss of insulation life can increase the risk of failures (for example, the risk of bubble formation). SIGMA Simulation is a…
Smart Trafo
Capture of information and readings on substation equipment, such as power transformers, began with electro-mechanical devices and handwritten notes made by operators, later evolving to electronic equipment with analog transmission of readings. Currently, with the widespread use of micro-controllers, microprocessors and computers, digitized information has become the most efficient and economical manner of capturing data…
SIGMA – Hydro On-line Monitoring Sub-system Oil and Solid Insulation Humidity
The presence of an excess water in a power transformer’s insulation system, in either the oil or solid insulation, causes diverse well-known negative effects. These including the lowering of the dielectric rigidity at low temperatures and the migration of water to and from the insulation paper, with the risk of bubble formation and rapid ageing…
