TAPGUARD® 240
Standard monitoring system for on-load tap-changers
Your benefits at a glance
|
Product description
With the TAPGUARD® 240 online monitoring system, monitoring the current operating status of your MR tap changer could not be easier. The TAPGUARD®240 determines service intervals and contact wear and moreover determines the oil carbonization of OILTAP® on-load tap-changers. With the condition-based maintenance option, the TAPGUARD® 240 reduces the lifetime product costs of your tap changer and prevents unexpected loss of service. Via an integrated log book, the operation and maintenance history of the tap changer is recorded.
The TAPGUARD® 240 is available as an optional function of TAPCON® 240 or TAPCON® 260 voltage regulators or as a standalone 19" device.
Reduce the lifecycle costs of your MR tap changer and increase the reliability of your transformer with the TAPGUARD® 240.
