BM Online Condenser Bushing Power Factor and Capacitance Monitors
Condenser bushings are accessories applied on high and extra-high voltage equipment, such as power transformers, shunt reactors and high voltage circuit breakers. In general, despite the equipment’s individual cost being relatively low as compared to the overall cost of the equipment to which it is attached, a failure in the bushing’s insulation can bring about…
GMP Periscope – Enhanced Dissolved Gases and Moisture in Insulating Oil Sensor
Monitoring the presence and evolution of gases dissolved in insulating oil of high voltage equipment such as power transformers and reactors, is an effective tool for diagnosing its operation conditions. However, measurements of these gases in the laboratory, through tests of gas-chromatography in oil samples collected periodically can allow a problem to start and evolve…
TMV Temperature Monitor + Regulation
Two complementary elements in transformer monitoring are temperature and voltage regulation. For smaller transformers, in which simplified monitoring is acceptable and even desirable.The TMV meets these two needs both working as temperature monitor and voltage regulator. This combines the functions of the TML and IDV, functionality performed by just one device. Based on measurements and…
TML Winding and Oil Temperature Supervisor
Treetech’s TML Temperature Supervisor is a thermal protection digital system that also controls the forced cooling of transformers and reactors immersed in oil. It is ideal for low cost small to medium- size equipment applications. For medium to large size/strategic applications or application that require equipment of Temperature Monitor class, please apply the following products:…
AVR+Intelligent Device for Voltage Regulation and On Load Tap Changer(OLTC) Monitoring
With innovative resources for more accurate voltage regulation, the AVR+ Intelligent Device by Treetech goes beyond a traditional regulating relay, allowing smart voltage regulation, better energy quality and smaller losses. The OLTC maintenance management optional functions permit the optimization and reduction ofmaintenance costs, are extended if associated with thermal monitoring with the OLTC temperature differential…
LAD – Temperature Monitor for Dry Transformers, Motors and Generators
Thermal monitoring of electric equipment, such as dry transformers, motors, generators facilitating safe operation maximising yield from these assets without endangering or shortening its service life. The LAD temperature monitor has six inputs for temperature measurements, monitoring multiple temperatures. Some of the typical applications for LAD: Phases a, b and c temperatures of dry transformers…
BAC – Binary Coded Decimal BCD to Analog Converter
Several techniques can be used for OLTC position remote transmission and measuring. One of them is to use a digital signal encoded in the BCD (binary- coded decimal) format, usually generated from dry contacts connected to a diode matrix in the OLTC activating mechanism. The BCD / Analog Converter from Treetech performs the conversion of…
SS – Surge Suppression Module
The Surge Suppression Module or SS has the function to protect the service life of electronic equipment against transient voltage surges from external sources in an electric power substation. The external and internal transient voltage surges directly affect the performance and the service life expectancy of electronic equipment. Available to protect power supplies from 0…
SPS – Parallelism Supervisor
The Synchronous Parallelism Supervisor SPS is a device developed by Treetech for control and supervision of parallel operation of power transformers equipped with a load tap changer. The SPS incorporates functions of a range of equipment that, in the past, were used to control parallel transformers, such as position indicators, auxiliary relays for electro-mechanical logic,…
