15,000 V insulation tester

With its site-proof casing, the C.A 6555 insulation tester is used to check equipment insulation during manufacturing, on-site installation work, periodic inspections and recommissioning of installations.

They are ideal for electricity companies, manufacturers, installers, maintenance firms, industry, R&D centres and infrastructure.

Specially adapted for checking insulation on rotating machinery with a 12 kV power supply or higher, the C.A 6550 complies with the IEEE43
standard which recommends testing insulation at 5-10 kV.
