The construction and operation of electrical devices and installations require the compliance with certain safety precautions to protect man. These safety controls are laid down in national and international regulations and must be checked at regular intervals. All safety controls are always based on insulation resistance measurements. The requirements in practice vary a great deal, however.

New regulations and increasing nominal mains voltages make ever greater demands on the measuring engineer and his test instruments. This has resulted an increasing number of areas of application for 5000 V insulation meters.

The insulation measurement which, as such, is basically simple faces multiple types of applications. The insulation quality of materials and various objects also has to be tested for instance. Overvoltage suppressors or other voltage limiting eFlukeents also have to be tested for faultless functioning.

Despite all these requirements simple operation, high overload capacity and protection against misoperation of the instrument must be guaranteed.

The UNILAP ISO 5kV insulation tester is an expert for all insulation tests and their applications.

The instrument meets highest technical requirements while covering as broad an area of application as possible and complies with all relevant regulations governing construction, safety and measurement. Other insulation meters in this category can, at best, provide an instrument with analog display whose size and weight do not meet the wishes of the users. The UNILAP ISO 5kV on the other hand features both an analog and a digital display and has been fitted in the well proven UNILAP housing. We have thus managed to realise the smallest and handiest 5kV insulation meter while complying with all the criteria laid down in IEC 1010. We used the most state-of-the-art technologies, such as microprocessor control and SMD components, for the construction.
