6 FAQs about [Capacitor error data]
What is the measurement error of capacitor voltage Transformers (CVTs)?
The measurement error of capacitor voltage transformers (CVTs) has poor stability under the complex environment of substations. Conventionally, error detection is performed by regularly comparing the output of standard transformers, which lacks real-time performance. Moreover, CVTs are prone to operating in an out-of-tolerance state.
How accurate are capacitive voltage transformer metering errors?
The metering accuracy of capacitive voltage transformers (CVTs) affects the fairness of electricity settlement, and the online measurement of their metering errors has become a research hotspot. This error consists of amplitude and phase errors of three-phase voltages.
How to recover from a capacitor error?
To recover from such a capacitor error, CapOS electrically isolates the degraded capacitor—so that it restores its original capacitance by itself with the help of capacitor’s resilient nature—and disables the JIT checkpointing.
Can capos solve the capacitor error of energy harvesting systems?
Once the capacitor is fully recovered, CapOS gets back to the capacitor-based JIT checkpointing. The experimental results demonstrate that CapOS can effectively address the capacitor error of energy harvesting systems at a low run-time cost, without compromising the recovery of power outages.
Is online measurement error a hotspot in electric power research?
Its online measurement error is one of the research hotspots in the field of electric power. In this paper, by analyzing data characteristics and the coupling between data, an improved deep learning model based on GRU and MTL is proposed, and three strategies are used to improve the model structure.
How accurate is a capacitive voltage transformer?
