介電系數(shù)，是一個在電的位移和電場強(qiáng)度之間存在的比例常量。這一個常量在自由的空間（一個真空）中是8.85?10的-12次方法拉第/米（F/m）。在其它的材料中，介電系數(shù)可能差別很大，經(jīng)常遠(yuǎn)大于真空中的數(shù)值，其符號是eo。 在工程應(yīng)用中，介電系數(shù)時常在以相對介電系數(shù)的形式被表達(dá)，而不是絕對值。如果eo表現(xiàn)自由空間（是，8.85?10的-12次方F/m）的介電系數(shù)，而且e是在材料中的介電系數(shù)，則這個材料的相對介電系數(shù)（也叫介電常數(shù)）由下式給出：ε1=ε / εo=ε?1.13?10的11次方 很多不同的物質(zhì)的介電常數(shù)超過1。這些物質(zhì)通常被稱為絕緣體材料，或是絕緣體。普遍使用的絕緣體包括玻璃，紙，云母，各種不同的陶瓷，聚乙烯和特定的金屬氧化物。絕緣體被用于交流電（AC），聲音電波（AF）和無線電電波（射頻）的電容器和輸電線路。

測試介電強(qiáng)度的儀器信息

介電擊穿強(qiáng)度試驗(yàn)儀滿足GB1408.1-2006要求，主要適用于固體絕緣材料如：塑料、薄膜、樹脂、云母、陶瓷、玻璃、、絕緣漆等介質(zhì)在工頻電壓或直流電壓下?lián)舸?qiáng)度和耐電壓時間的測試；該儀器采用單片機(jī)控制，可對試驗(yàn)過程中的各種數(shù)據(jù)進(jìn)行快速、準(zhǔn)確的采集、處理，并可存取、顯示、打印 的一種測試儀器。

電氣強(qiáng)度（Dielectric strength），指擊穿電壓比上擊穿樣品的厚度等于樣品的電氣強(qiáng)度。

在物理學(xué)中，術(shù)語電氣強(qiáng)度具有以下含義：

絕緣材料中，純材料在理想條件下可以承受的最大電場而不會損壞（即不會經(jīng)歷其絕緣性能的失效）。

材料的理論電氣強(qiáng)度是大塊材料的固有屬性，并且與施加電場的材料或電極的構(gòu)造無關(guān)。這種“固有介電強(qiáng)度”對應(yīng)于在理想實(shí)驗(yàn)室條件下使用純物質(zhì)測量的值。在擊穿時，電場釋放束縛的電子。如果施加的電場足夠高，來自背景輻射的自由電子可能會加速到在被稱為雪崩擊穿的過程中與中性原子或分子碰撞期間釋放額外電子的速度。擊穿發(fā)生得相當(dāng)突然（通常在幾納秒），導(dǎo)致通過材料形成導(dǎo)電路徑和破壞性放電。對于固體材料，擊穿事件嚴(yán)重降低，甚至破壞其絕緣能力。

The dielectric constant is a proportional constant that exists between the displacement of electricity and the strength of the electric field. This constant in free space (a vacuum) is 8.85 ? 10 ^ -12 times the method pull per meter (F/m). In other materials, the dielectric constant may vary greatly, often much greater than the value in vacuum, and its symbol is eo. In engineering applications, the dielectric constant is often expressed in the form of relative dielectric constant rather than absolute value. If eo represents the dielectric constant of free space (8.85 ? 10 ^ -12 F/m), and e is the dielectric constant in the material, then the relative dielectric constant (also known as the dielectric constant) of this material is given by the following equation: ε 1=ε/ε o=ε ? 1.13 ? 10 ^ -11. Many different substances have dielectric constants exceeding 1. These substances are commonly referred to as insulating materials or insulators. Commonly used insulators include glass, paper, mica, various types of ceramics, polyethylene, and specific metal oxides. Insulators are used in capacitors and transmission lines for alternating current (AC), acoustic waves (AF), and radio waves (RF).

Instrument information for testing dielectric strength

The dielectric breakdown strength tester meets the requirements of GB1408.1-2006 and is mainly suitable for testing the breakdown strength and withstand time of solid insulation materials such as plastics, films, resins, mica, ceramics, glass, insulating paints, etc. under power frequency voltage or DC voltage; This instrument is controlled by a microcontroller and can quickly and accurately collect and process various data during the experimental process. It is a testing instrument that can be accessed, displayed, and printed.

Electrical strength refers to the ratio of the breakdown voltage to the thickness of the breakdown sample, which is equal to the electrical strength of the sample.

In physics, the term electrical strength has the following meanings:

In insulation materials, pure materials can withstand the maximum electric field under ideal conditions without damage (i.e. without experiencing failure of their insulation performance).

For the specific configuration of dielectric materials and electrodes, the minimum applied electric field that causes breakdown (i.e., the applied voltage divided by the electrode separation distance).

The theoretical electrical strength of a material is an inherent property of bulk materials and is independent of the construction of the material or electrode to which an electric field is applied. This' intrinsic dielectric strength 'corresponds to the value measured using pure substances under ideal laboratory conditions. During breakdown, the electric field releases bound electrons. If the applied electric field is high enough, free electrons from background radiation may accelerate to a speed that releases additional electrons during collisions with neutral atoms or molecules, known as avalanche breakdown. The breakdown occurs quite suddenly (usually in a few nanoseconds), leading to the formation of a conductive path and destructive discharge through the material. For solid materials, breakdown events are significantly reduced, and even their insulation ability is damaged.
