Fluke 1623-II Kit - Tester uzemnenia

Jednoduchá metóda "bez rozpojenia zemniča" rýchlo skontroluje spojenie so zemou pomocou dvoch prúdových transfomátorov (sond) pripojených prúdovými kliešťami k testovanému zemnému vodiču. Tester 1623 s jednoduchým jednotlačítkovým ovládaním je tester uzemnenia, ponúkajúci všetko v jednom prístroji, zatiaľ čo tester 1625 obsahuje dodatočné univerzálne možnosti pre náročnejšie aplikácie.

Odpor uzemnenia a merný odpor pôdy sa musí merať pri:

• Projektovanie zemných systémov
• Inštalácia nových pozemných systémov a elektrického zariadenia
• Periodické testovanie zemniacich ochranných systémov a hromozvodov
• Inštalácie veľkých elektrických zariadení, ako sú transformátory, rozvádzače, stroje atď.

Progresívna technológia pre všetky aplikácie testovania uzemnenia

• Jednotlačítková koncepcia merania
• 3 a 4 pólové meranie zemného odporu
• 4-pólové testovanie odporu pôdy
• 2-pólové AC(st) meranie odporu
• Selektívne testovanie bez rozpojenia zemniča (1 kliešte)
• Testovanie bez zemných sond, rýchle testovanie zemnej slučky (2 kliešte)
• Meranie frekvencie 128 Hz
• Odolnosť voči prieniku prachu a vody IP56
• Bezpečnostná kategória CAT II 300V

Sada Fluke 1625 kit obsahuje:

• Ochranné púzdro
• 2 meracie káble
• 2 krokosvorky
• 1 skratovacia prepojka
• Sada sond/cievok na 4 pólové meranie
• Sada s kliešťami
• Užívateľská príručka
