The power transformer guard (PTG) is an integrated system with dual ability to measure both vibration and temperature for the purpose of extending your as set lifetime .
the power transformer guard is designed to monitor oil filled power transformer in order to extract a signature of its condition without such condition monitoring (CM) ability its difficult to know when your transformer needs to be serviced or replaced .
The PTG measures vibration in the frequency range of 20-1000 HZ to display the various components of the vibration .
the largest vibration comes from winding's / coils whose shape is lost as a consequence of excessive vibration .an excessive amplitude leads to play in the coils .
Existing play allows large amplitude vibration , which in turn reinforces the play .
It is a vicious cycle if left unchecked. At worse, a total breakdown of your transformer will happen resulting in catastrophic failure .
Adopting PT guard is the key to a robust system . It provides long term monitoring of your transformer behavior and the ability to react before catastrophic failure leads to increase expenses .
PTG sensors are 2mm thin , resistant to high temperature immune to EMI and high voltages and are
designed to be installed inside the tank between the winding turns and submerged in the cooling oil .
