Challenges in overhead line monitoring
Overhead power lines are required to reach the most remote or inaccessible locations, often traversing very different weather systems. This presents both operational and maintenance challenges for operators.
From an operational perspective, the challenge is Dynamic Line Rating (DLR), and to know the line ampacity, or its safe thermal limits at critical points along the route in real time. This is influenced heavily by variable weather conditions, principally wind velocity and solar radiation, and by the circuit load current.
From a maintenance perspective, the challenge is the cost and low frequency of manual inspection visits to identify potential failures, such as storm damage, ice accretion, or hotspots from conductor fatigue.
Our passive sensors are ideal for automating both monitoring tasks in one system (Synchromerger™), providing earlier warning to failures in the most remote and inaccessible places.
Synaptec’s unique, passive sensors are retrofittable to any number of individual conductors and towers to give live and detailed visibility of sag, vibration, and temperature. By correlating mechanical measurements from our line-mounted sensors with electrical current monitoring, we provide true DLR with a more detailed, instantaneous and localised view of ampacity than weather forecasts for a general area.
Without any need for cellular network access, power supplies, batteries, maintenance, or recalibration, our passive sensors can be deployed safely and rapidly anywhere. We provide real-time, synchronous, and permanent monitoring of temperature, vibration, strain, current, and voltage in the same system. This provides early warning of failures to enable more efficient maintenance, and location-specific validation of ampacity estimates derived from weather data.
