Kewtech KEW3125A High Voltage 5kV Insulation Tester
The Kewtech KEW3125A is the UK’s smallest 5kV insulation tester capable of producing resistance measurements up to 1 Terra Ohm.
Test voltages can be selected from 250VDC to 5000VDC to suit a wide range of test applications, whilst timed tests and PI/DAR tests can be performed making the KEW3125A suitable for cable diagnostic checks. Moreover the Kewtech KEW3125A 5kV tester features an electrical noise filter, allowing for stable measurements within HV substations where electrical interference could cause inconsistent test results.
The Kewtech KEW3125A is supplied inside a hard carry case suitable for most environments along with a line probe, an earth probe, a guard probe and a hook probe; ideal for hooking over electrical busbars and power lines.
