- Definition(s)
- Shortest distance or the sum of the shortest distances along the surface on an insulator between two conductive parts which normally have the operating voltage between them. Internat. Electrotechnical Commission
- Example sentence(s)
- Although solid insulation dielectric strength is important, the usual bottleneck for high voltage is creepage distance, such as margins between wire and core along the layers of insulation, or margins between lead joints and frame along the leads and coil sides. - Reuben Lee by
- For design purposes, the specific knowledge about the creepage distance of the insulator for the contaminated environment is important. This can be done easily if the mathematical relationship between the creepage distance and Salt Deposit Density (SDD) is known. - IEEE Xplore by
- The higher the pollution degree, the worse the environment. For obvious reasons, the creepage distance required for safety will need to be greater to account for increased pollution. - Lamothe Approvals Inc. by

- Definition(s)
- Il più breve percoso fra due superfici conduttrici o tra una parte conduttrice e la superficie limite dell'apparecchiatura, misurato lungo la superficie del materiale isolante. Nome CEI - by Simona Corsellini
- Example sentence(s)
- In base alle precedenti considerazioni si può comprendere perché gli isolatori usati negli elettrodotti siano particolarmente lunghi (anche metri) e costituiti da dischi sovrapposti con superficie irregolare invece che semplici cilindri. In questo modo si aumenta la distanza superficiale rispetto alla distanza in aria. - Wikipedia by Simona Corsellini
- Nell’interpretazione data dalla norma europea il peggiore dei casi è considerata una differenza di potenziale di 230V (240V) corrispondente ad un guasto sulla rete di alimentazione; in questo caso la distanza superficiale minima richiesta tra TNV e SELV e TNV e terra è 2,5mm. - Sicurezza elettrica by Simona Corsellini
- Un perno conduttore folle (girevole e orientabile) che permette di ottimizzare la distanza superficiale tra più isolatori passanti inseriti in un’unica scatola di alimentazione (migliorando la gestione degli spazi all’interno della scatola stessa). - Confartigianato by Simona Corsellini

- distance la plus courte ou somme des distances les plus courtes le long de la surface d’un isolateur entre deux parties conductrices qui supportent normalement la tension de service entre elles. IEC - by Jean-Christophe Vieillard
- Example sentence(s)
- NOTE 1 – La surface du ciment ou de toute autre matière de scellement non isolante n’est pas considérée comme faisant partie de la <b>ligne de fuite</b>. - IEC by Jean-Christophe Vieillard
- NOTE 2 – Si un revêtement à haute résistance est appliqué sur certaines parties isolantes d’un isolateur, ces parties sont considérées comme surfaces isolantes effectives et la distance mesurée à la surface de ces parties est incluse dans la <b>ligne de fuite</b>. - IEC by Jean-Christophe Vieillard

- Az a legkisebb távolság, amely a két vezető-képes rész között a szigetelőanyag felületén mérhető; a kúszóút. Hobbi Elektronika - by Gyorgy Banhegyi
- Example sentence(s)
- A belsőtéri szigetelők zárt térben, a szennyezésektől és a közvetlen légköri hatásoktól védve üzemelnek, ennek megfelelően a kialakításuk egyszerűbb (bordázás, kúszóút, szerelvények). - personal website by Gyorgy Banhegyi
- A TK-t úgy kell kiválasztani, hogy kúszóútja a beépítési hely
szennyezettségi szintjének megfelelõ legyen. - journal by Gyorgy Banhegyi

- 「充電部と非充電部との短絡による事故を防ぐ為に、空間距離および沿面距離についてそれぞれ定められた安全規格」があるそうなのですが、詳しく教えていただけないでしょうか?
自分で調べた範囲では、安全規格IEC/EN60950、61010、60601の中に記載されいるらしいのですが、詳しい内容までは分かりませんでした。
日本国内法では 電気用品安全法(以前は電気用品取締法)に規定があります。
使用される場所,電圧などにより 要求されている距離が異なり
『附表第二 コンデンサー以外の充電部の空間距離(沿面距離を含む。)』 に記載されています。 - 技術の森No.20225-空間距離と沿� by Yasutomo Kanazawa
- 図1に示すように、絶縁のための距離には空間距離と絶縁体の沿面に沿った沿面距離があります(図1では二つの例を示したが他にもさまざまな形状について定められている)。そして電位差、設置箇所および設置される環境によって、空間距離と沿面距離の最小値が定められています。 - 電気回路と定数設計と部品選� by Yasutomo Kanazawa
- -2. JIS規格(JIS C 1102-1)改正
安全に関する引用規定がIEC414からJIS C 1010-1に変更になりました。
これに伴い電圧試験の試験電圧と試験時間、使用回路電圧に対する沿面距離等の要求事項が変更になりました。 - 三菱配電・制御機器セールス� by Yasutomo Kanazawa
