Electrical strength testing, also known as withstand voltage testing. Simply put, any electrical equipment has an insulation level, and the insulation level varies depending on the rated voltage. When a certain voltage level is exceeded, the insulation of the equipment will be broken down. Electrical strength testing is to apply a certain high voltage to the tested equipment (refer to IEC standards or national standards) to see if it will cause breakdown. If it does not break through, it passes; if it breaks through, it indicates that it is unqualified. Usually, this test is conducted before the equipment leaves the factory. On site, it can be done simply by shaking the insulation. In addition, this test is a destructive test and once it breaks down, it cannot be corrected. Electrical strength testing, also known as withstand voltage testing, is the process of examining the characteristics of a coiled insulation material that exhibits conductive properties after being punctured. By querying the changes in electrical parameters, it is determined whether the insulation material has been punctured.

The critical flashover strengths obtained in these situations are referred to as dry flashover strength, wet flashover strength, and dirty flashover strength, respectively. Due to the uneven voltage distribution at the interface of the medium, the flashover voltage along the surface is lower than the breakdown voltage when gas or solid exists alone.

The discharge along the interface between solid insulation and air, which develops into a penetrating air breakdown, is called flashover. The voltage value required to cause flashover on the outer insulation surface under certain experimental conditions is called the critical flashover strength. Sometimes the flashover strength is indicated by a uniform flashover field strength.

The volt second characteristic refers to the relationship curve between the impulse discharge voltage of insulation and the corresponding discharge time under the premise of a certain impulse voltage waveform. The volt second characteristic is determined by experiments, and the method is to maintain the waveform of the impulse voltage unchanged and gradually increase the voltage. When the voltage is low, breakdown occurs at the tail of the wave; When the voltage is very high, the discharge time is reduced to a very small amount, and breakdown can occur at the wave head. When the wave tail hits through, take the amplitude of the impulse voltage as the vertical axis and the discharge time as the horizontal axis.

The insulation strength of external insulation is closely related to external atmospheric conditions, and is influenced by various factors such as atmospheric temperature, pressure, humidity, and dirt. The standard atmospheric conditions of the International Electrotechnical Commission are: pressure of 1013 millibars (1 bar=105 Pa), temperature of 20 ℃, humidity of 11 grams per cubic meter, and the conversion method between external insulation discharge voltages is specified for different atmospheric conditions. The measured voltage values under non-standard atmospheric conditions should be converted to the voltage values under standard atmospheric conditions; On the contrary, when using voltage values under standard atmospheric conditions, they should be converted to voltage values under atmospheric conditions during testing or operation.

Input voltage stabilization system (reducing external voltage acquisition fluctuations)
The insulation of electrical equipment with volt second characteristics not only bears the effect of long-term working voltage, but also the effect of transient overvoltage.
One type is overvoltage caused by lightning strikes on equipment or induced by lightning strikes near equipment; Another type is overvoltage caused by operations, incidents, or resonances in the power system. The duration of overvoltage is short, but the value of overvoltage greatly exceeds the normal operating voltage. The unfolding of discharge requires a certain amount of time, and under the continuous voltage, the discharge delay has no effect on the discharge voltage;
Input voltage: AC 220V
Wireless Bluetooth control eliminates distance barriers and makes human-machine separation more convenient.
However, regarding the impact voltage with a short duration of action, the influence of discharge delay cannot be ignored.
