T&R Test Equipment KV30-100 MK3 AC Test System
Professional High Voltage AC Tester for Insulation Testing
The T&R Test Equipment KV30-100 MK3 AC Test System is a robust, high-performance High Voltage AC Tester designed for precise insulation testing in laboratory, manufacturing and maintenance environments. Built in the UK to exacting standards, this system delivers dependable performance where accuracy, safety and repeatability are critical.
With a continuously variable 0–30kV range and a powerful 3kVA capability, the KV30-100 MK3 is ideally suited to both development work and routine electrical testing. Its stable hv output and comprehensive protection features give engineers confidence during every test cycle.
Designed for Accurate Control and Safe Operation
This AC test system consists of a dedicated control unit paired with a separate oil-filled high voltage transformer, connected via 5-metre supply and control cables. This configuration ensures excellent electrical stability while allowing flexible installation within a compliant high voltage test area.
The control unit provides intuitive operation with clear analogue voltage and current metering, allowing operators to monitor the hv output accurately throughout testing. A variable electronic trip enables precise control of trip current from 10% to 110% of rated output, protecting both the operator and the test object during fault conditions.
The oil-filled transformer is housed in a welded steel tank with swivel castors for ease of positioning. Its high voltage bushing delivers a stable hv output while the earthed winding configuration enhances operational safety. This High Voltage AC Tester is suitable for testing capacitive, resistive and inductive loads across a wide range of applications.
