RR – Rapid Auxiliary Relay
he function of the Rapid Auxiliary Relay – RR is to multiply a signal into several independent contacts without a substantial time delay in its transmission. The importance of the response time may be noticed, for instance, when the relay is used in protection systems for power transformers, where a small delay in the emission…
DTM -Temperature Monitor for Dry Transformers, Motors and Generators
Thermal monitoring of electrical equipment, such as dry transformers, motors, generators and others is essential in operating them safely, thus allowing maximum return from the investment in these assets to be achieved without jeopardizing their life cycle. The DTM Temperature Monitor has three temperature reading inputs (optional fourth input), allowing monitoring of multiple temperatures. A…
MBR – Membrane/Bag Rupture Relay
The Membrane/Bag Rupture Relay – MBR is a device capable of detecting the rupture of the rubber membrane or bag used in oil preservation systems on power transformers and reactors. The MBR is comprised of an optical sensor that must be mounted on the membrane or inside the rubber bag (on the air side), and…
MO – Online Moisture in Oil Monitor
Excess water in the insulating oil of high voltage equipment, such as transformers and reactors, causes well known adverse effects. High moisture content will cause reduction in dielectric rigidity and migration of water into the insulating paper, with the risk of formation of bubbles and accelerated aging in the presence of high temperatures, thus jeopardizing…
COMM – Communication Module
The Serial Communication Module – COMM is designed to serve as an interface between microprocessor based devices equipped with serial communication and a computer. This interface is necessary, for instance, when the communication port of the devices is already in use for data interchange between them. This data interchange must operate continuously independently of the…
DM – Data Acquisition and Control Modules
The Data Acquisition and Control Module – DM provides a digital systems interface with any analog or electromechanical equipment that does not have a serial port and needs to be supervised or controlled. Three versions are available, each version with options of 8, 16, and 24 inputs/outputs: DM – 1 for the supervision of dry…
CBS – Circuit Breaker Supervisor
Nowadays there is an increasing concern about the electric system reliability. All the essential equipment must be monitored continually so that the system can operate with minimum interruptions. The circuit-breakers and blocking relays are some of these essential assets, so they have to be maintained in operational condition to perform in case of serious faults…
TM1 & TM2 – Temperature Monitors
More than just digital thermometers, Treetech’s TM Temperature Monitors form a complete Temperature Monitoring system for transformers and reactors immersed in oil. Designed as a modular system, it can be used in simple, low cost applications, as well as in complete monitoring systems. The system is comprised of modules TM1and TM2: • TM1, monitors the…
