How much electrostatics is there when you are fueling?

Welcome to ALPTEC electrostatic laboratory!


Testing tools: Simco Electrostatic Field Meter, Personal Electrostatic Measurement Kit, Temperature and Humidity Meter, Tripod.

Testing Method: The conductive wrist strap is connected with FMX-003 Electrostatic Field Meter and FMX-003 is connected with the grounding stud, it will show the personal real-time electrostatic voltage.


Testing environment: 

Temperature: 19.5; Humidity: 34.8%

01.How much electrostatics can people generate who wearing sweater when they get off the car?

Get off the car
The maximum electrostatic voltage is 11.2 kv.
Let it stand
The electrostatic voltage is 7.3kv after standing.

Conclusion:

The personal electrostatic is up to 11.2kv, and it is still above 5kv after standing. It will generate strong static electrostatic discharge when touching metal or door.—It is very dangerous!

02.How much electrostatics can people generate who wearing different materials clothes when they get off the car?

                                                                           Wearing pure cotton coat:

 Get off the car

The maximum electrostatic voltage is up to 8.1kv.


Let it stand.
The electrostatic voltage is up to 5.7kv after standing.

                                                                            Wearing pure down jackets

 Get off the car

The maximum electrostatic voltage is up to 11.1kv.



Let it stand.
The electrostatic voltage is up to 7.6kv after standing.

                                                                        Wearing pure woolen coat

 Get off the car

The maximum electrostatic voltage is up to 10.4kv.



Let it stand.
The electrostatic voltage is up to 4.7kv after standing.

The video of the whole process of the above test.

Conclusion:

The electrostatic voltage of warm clothing is all over 10000 V! The electrostatic generated by different materials of clothing is different. According to the actual measurement, the electrostatic voltage has far exceeded the safe value (500 V), and violent discharge will occur when touching metal objects.

03.How much electrostatic can be generated when close to charged objects after discharging electrostatic?


The body instantly induces 2kv electrostatic when close to the seat carrying electrostatic after eliminating static electricity.



Conclusion:

The personal electrostatic is generated in an instant. Even if the electrostatic discharge is completed, when the human body is close to the seat or clothes carrying electrostatic, it will instantly generate up to several thousand volts of induced electrostatic, and a violent discharge will occur when it touches a metal object.

04.What does 11kv electrostatic discharge look like in slow motion?

Note: The test video was recorded outdoors during the day, and the spark could not be captured.

The discharged energy not only has a great risk of ignition, but also a strong stimulation of human nerves, which can easily lead to secondary accidents.


Under ordinary clothes, the generation of electrostatic is fast, and the voltage is higher than we can imagine. It may be a simple action that can generate electrostatic up to several thousand volts. The existence of this dangerous electrostatic seriously threatens safe production.

Electrostatic is not visible. Only when spark discharge occurs can you know whether there is dangerous electrostatic.

Electrostatic needs to be seen and monitored to ensure the safety of electrostatic in a safe place.


After many years of independent research and development in ALPTEC, the research achievements of Electrostatic Monitoring Eliminator can implement the detection of electrostatic in the space. Once electrostatic is found to exceed the dangerous value, it will immediately alarm the personnel to eliminate electrostatic!
