Megger FRAX99, FRAX101 and FRAX150 SWEEP FREQUENCY RESPONSE ANALYSERS
The FRAX series of sweep frequency response analyzers (SFRA) detects potential mechanical and electrical problems that other methods are unable to detect. Major utilities and service companies have used the FRA method for more than a decade. The measurement is easy to perform and will capture a unique fingerprint of the transformer. The measurement is compared to a reference fingerprint and gives a direct answer if the mechanical parts of the transformer are unchanged or not. Deviations indicate geometrical and/or electrical changes within the transformer.
The Qualitrol DGA-LT1 is a cost effective wireless transformer monitor specifically designed for monitoring failure and safety risks on distribution pad mount transformers. The DGA-LT1 automatically measures dissolved hydrogen concentration, moisture concentration and temperature of dielectric insulating oil. The monitor takes only minutes to install and requires no costly power or communications cables. Data is securely stored and analyzed on the QualConnex platform to provide alert notifications on high concentrations or high rate of increasing concentrations. The DGA-LT1 brings a cost-effective means to reduce site safety risks and prevent costs associated with unplanned outages due to failures. The DGA LT1 leverages the QGateway RF to TCP/IP for encrypted and highly secure data transfer.
Capillary based, mechanical, remote indicating thermometer. Configurations for oil temperature measurement and winding temperature simulation. Features up to 6 adjustable switches for alarm, trip, and cooling system functions and can be equipped with various electronic outputs for SCADA and remote monitoring applications.
Top mounting bi-metal thermometers with temperature indication and a reset-able maximum temperature pointer. Most models can be screwed into a pocket (well) that allows units to be exchanged without draining the tank. Made of corrosion resistant materials for long life and high accuracy performance.
