Types of electrical tester in this category

Insulation testers such as the Chauvin Arnoux CA 6505, CA 6541 and CA 6550, Hioki IR5050 and IR4056 and Fluke 1507 test cables and motors up to 10 kV. Earth testers like the Hioki FT6031 and FT6041, Chauvin Arnoux CA 6422 and CA 6471 and Metrel MI 3290 measure earth resistance and soil resistivity. Multifunction installation testers (Metrel MI 3152, Chauvin Arnoux CA 6116N), low resistance ohmmeters (Megger DLRO10X, Metrel MI 3242), relay test systems such as the Megger SMRT410, TDR cable fault locators, multimeters and clamp meters complete the range.

How to select a electrical tester

Define the tests required (insulation, earth, loop, RCD, continuity, micro-ohm), the voltage levels of the equipment, and standards such as IEC 61557 or IEC 60364. Choose test voltage and resistance range, memory and reporting, and CAT safety rating for the installation.

Frequently Asked Questions

Which insulation test voltage should I use?
It depends on the rated voltage of the equipment. Low voltage installations are usually tested at 500 V or 1 kV, medium voltage equipment at 5 kV or 10 kV.
What is an earth resistance tester used for?
To measure the resistance of earth electrodes and grounding systems, and soil resistivity for earthing design.
What does CAT rating mean?
The measurement category in IEC 61010 that defines the transient overvoltage a meter can safely withstand, from CAT II to CAT IV.
What is a micro-ohmmeter for?
Measuring very low resistances such as busbar joints, breaker contacts and cable splices.
What should I send for a quotation?
The model, or tests, test voltage, ranges, standards, accessories and quantity.
