Research on Low - Voltage Anti - DC Current Transformer and Detection Device
1. Overview of Components and IssuesTA (low-voltage current transformer) and electric energy meters are key components of low-voltage electric energy metering. The load current of such meters is no less than 60A. Electric energy meters vary in type, model, and anti-DC performance, and are connected in series in the metering device. Due to the lack of anti-DC capability, they suffer from metering errors under DC component loads, usually caused by non-linear loads. With the increasing use of DC or

Anti - Theft Device for Low - Voltage Current Transformers
1. Innovation BackgroundWith the progress of society and economic development, the electricity demand of power users is expanding increasingly. Lawbreakers, aiming to save electricity costs and pursue high profits, gradually use high - tech methods to steal electricity, causing huge economic losses to power supply enterprises. Currently, popular electricity theft methods in the market include illegally opening the wiring cover of low - voltage transformers in electric energy metering boxes, alte

What are the impacts of temperature on AIS voltage transformers?
Impact on Insulation PerformanceChanges in Insulating Material Properties: AIS voltage transformers rely on air as the insulating medium, and they also contain some solid insulating materials, such as insulating paper and insulating bushings. When the temperature rises, the migration and evaporation of moisture in solid insulating materials like insulating paper will accelerate, resulting in a decrease in the electrical strength of the insulating materials and an increased risk of insulation bre

Fault Analysis of Single - Phase Grounding of Three - Phase 4PT Voltage Transformer
In 10 kV and 35 kV ungrounded systems, single - phase grounding faults cause minimal current, so protection rarely trips. Per regulations, operation is limited to 2 hours; prolonged undetected faults may worsen, even damaging switches. While the State Grid promotes small - current grounding line selection devices in 110 kV and 220 kV substations, their accuracy remains low, requiring monitoring/operation staff to analyze remote measurements. For ungrounded systems with three - phase 4PT voltage
