First Claim
Patent Images
1. A fault gas alarm system comprising:
- a gas sensor configured to fluidly connect with an oil valve in an oil-filled vacuum-type on-load tap changer (OLTC), the gas sensor for monitoring a gas level in an oil within the oil valve; and
a bi-level alarm system electrically connected with the gas sensor, the bi-level alarm system including a visual alarm indicator configured to provide a visual alarm in response to receiving an indication the gas level in the oil exceeds a threshold.
