In the evening, when you get home, you can deliver cargo weapons in the garage; during weekend shopping you can contact the station fast load in the shopping center. Behind these everyday backgrounds there is a hidden danger of power leakage. Especially with regard to the unique DC fault current for electric cars, the traditional leakage protection can not be recognized at all. In this case, other current sensors are important to protect against leakage.
1.Home: Safety concerns for slow charging all night
Late at night, the electric car entered its own garage and began charging slowly for eight hours. My family has already slept, only the light on the load indicator lights in silence. In reality, the quiet loading process seems to contain hidden dangers - the exit of the wall can be internally advanced, and moisture can penetrate the circle. After generating DC fault current in the car, traditional type A leakage in the home can not recognize it and can completely collapse due to DC saturation. At three o'clock in the morning, the temperature dropped to its lowest point, and a weak electrical leak occurred in the aging pond in the circle. At the moment, the full current sensitive protection device integrated inside the charger was precisely determined for the anomaly, interrupted the power for milliseconds, and the sleeping family on the top floor was completely unaware of this quiet crisis.

2. Quick charging station for shopping mall: accurate identification in complex electromagnetic environments
2.1 Charge and electromagnetic interference scenarios
On weekends afternoons passejezdzą cars through underground parking to the shopping center. The owner of the car goes up to the top floor for shopping after starting the gun and exhausting the tip, surrounded by several charging stations working simultaneously, with the associated high-frequency noise and a complex electromagnetic environment. Many charging stations produce a large amount of electromagnetic interference during work, and the detector is exposed to poor work or indifference that leaks the right fault.
2.2 Precise management within millimeters
When the owner of the car purchased, the old electric car next to him caused a small DC outage due to the deterioration of the insulation. This residual leakage protection residual current sensor detects anomalies in real time and severely interrupts the power supply before the danger limit is reached, avoiding danger to the car's electric rocket.

3. Temporary outdoor load: reliable protection in harsh environments
3.1 Test of wind and rain in the service zone
During the summer vacation, cargo stations outdoors in fast service zones are exposed to burning sun, where the temperature of the earth reaches 40℃. After the owner of the car delivered the weapon and charged it, he went to relax. Suddenly a heat storm hit, and the cargo station was immediately dampened due to rain, causing a sudden drop in temperature. The temperature difference close to 20℃ in just half an hour is a great test of internal components, and the external equipment must also cope with challenges such as dust, vibration, etc.
3.2 Stable work after wind and rain
After the rain, the sky is clear and full. In extreme temperature differences, the internal Hall sensor always works stably without any shift in parameters. Another cargo station damaged by the building's earthquake made people realize how strict the requirements for the reliability of the outdoor view are.

4. Overall view of cargo requires uniform protection
From underground garages in residential areas to high-speed operating areas, from slow loading at home to fast loading outdoors–behind every load of the convenience of the car owner’s heart are invisible confidants working quietly. It is the HYCA-01 full current-sensitive residual current sensor that makes this protection a reality. As a highly efficient current sensor, it strictly complies with IEC 62752 and IEC 62955 standards to ensure load safety always online with the exact limits.

5. Conclusion
Whether it is slow charging late at night in the family garage, electromagnetic interference from fast charging stations in shopping malls or wind and rain tests in service areas in the air, the HYCA-01 always monitors every load quietly. You can travel in peace of mind, protecting yourself as one person.
