Oil temperature recording is a prerequisite for the self-learning of the yel-
low limit value curve. As an alternative to recording the OLTC oil tempera-
ture, the top-oil temperature can be used.
4.3 Function description
The product is a monitoring system for monitoring vibro-acoustic signals
from on-load tap-changers. You can use the product to detect time and am-
plitude anomalies in the vibro-acoustic signal progression and receive event
messages when anomalies are detected.
The on-load tap-changer is equipped with measuring equipment that records
the vibro-acoustic signal in the system throughout the entire tap change se-
quence and analyses it immediately upon completion. In addition, the sys-
tem determines the changed tap position and the oil temperature in the on-
load tap-changer.
