Hey there! As a supplier of AC DC High Voltage Dividers, I often get asked about the creepage distance of these devices. So, I thought I’d take a few minutes to break it down for you and explain why it’s such an important factor to consider when choosing a high voltage divider. AC DC High Voltage Divider<\/a><\/p>\n

First things first, let’s talk about what creepage distance actually is. In simple terms, creepage distance is the shortest distance along the surface of an insulating material between two conductive parts. In the context of an AC DC High Voltage Divider, these conductive parts could be the input and output terminals, or the high voltage and low voltage sides of the divider.<\/p>\n

The creepage distance is crucial because it helps prevent electrical breakdown and arcing across the surface of the insulator. When a high voltage is applied across a divider, there’s a risk that the electrical field can cause the air or other insulating material around the conductive parts to ionize. This ionization can create a conductive path, allowing current to flow across the surface of the insulator instead of through the intended circuit. This phenomenon is known as surface tracking or arcing, and it can lead to a variety of problems, including short circuits, equipment damage, and even safety hazards.<\/p>\n

By maintaining an adequate creepage distance, we can reduce the risk of surface tracking and ensure that the high voltage divider operates safely and reliably. The specific creepage distance required for a given application depends on several factors, including the voltage level, the type of insulating material used, and the environmental conditions in which the divider will be operating.<\/p>\n

Let’s start with the voltage level. Generally speaking, the higher the voltage, the greater the creepage distance required. This is because higher voltages create stronger electrical fields, which are more likely to cause ionization and surface tracking. For example, a high voltage divider designed for a low voltage application, say up to 1000 volts, might have a relatively short creepage distance of just a few millimeters. On the other hand, a divider intended for use in a high voltage power transmission system, where voltages can reach hundreds of thousands of volts, could require a creepage distance of several centimeters or more.<\/p>\n

The type of insulating material also plays a significant role in determining the required creepage distance. Different materials have different electrical properties, such as dielectric strength and surface resistivity, which affect their ability to withstand high voltages without breaking down. For instance, materials like ceramic and glass are commonly used in high voltage dividers because they have high dielectric strengths and good surface resistance, allowing for shorter creepage distances compared to other materials. Plastics, on the other hand, may require longer creepage distances due to their lower dielectric strength and higher susceptibility to surface tracking.<\/p>\n

Environmental conditions are another important consideration. Factors such as humidity, temperature, pollution, and the presence of chemicals or contaminants can all impact the performance of the insulating material and increase the risk of surface tracking. In environments with high humidity or pollution levels, for example, the surface of the insulator can become contaminated with moisture or conductive particles, which can reduce the surface resistivity and increase the likelihood of electrical breakdown. In such cases, a longer creepage distance may be necessary to ensure reliable operation.<\/p>\n

At our company, we take all of these factors into account when designing and manufacturing our AC DC High Voltage Dividers.

In addition to ensuring safety and reliability, maintaining an adequate creepage distance can also have other benefits. For example, it can help improve the accuracy and stability of the divider’s output. When surface tracking occurs, it can introduce noise and interference into the electrical signal, which can affect the measurement accuracy of the divider. By minimizing the risk of surface tracking through proper creepage distance design, we can help ensure that our dividers provide accurate and consistent measurements over time.<\/p>\n
