T&R Test Equipment KV50-200 Mk2 AC Test System
Precision High Voltage AC Tester for Demanding Insulation Testing
The T&R Test Equipment KV50-200 Mk2 AC Test System is a robust, high-performance High Voltage AC Tester engineered for accurate, repeatable insulation testing in both development and routine production environments. Designed and manufactured in the UK, the KV50-200 delivers dependable results where precision, safety and power truly matter.
With a powerful 0–50kV AC output and an impressive 10kVA capability, the KV50-200 is ideally suited for testing electrical insulation systems, components and plant under realistic operating stresses. This High Voltage AC Tester combines intelligent protection features with intuitive analogue metering, giving engineers complete confidence during every test cycle.
Engineered for Accuracy, Control and Confidence
At the heart of the KV50-200 is a dedicated control unit paired with a separate oil-filled high voltage transformer, connected via durable 5-metre interconnecting cables. This proven configuration ensures stable performance, accurate measurement and safe operation throughout the full test range.
Secondary tap metering is provided as standard, enabling precise voltage measurement even under load. Output voltage and current are clearly displayed on large, linear analogue instruments, allowing operators to monitor test conditions at a glance. As a professional High Voltage AC Tester, the KV50-200 gives you total visibility and control at all times.
A variable electronic trip system allows the trip current to be set between 10% and 110% of rated output, ensuring sensitive protection across a wide variety of test objects. From capacitive and resistive loads to inductive equipment, the KV50-200 adapts effortlessly to your application.
Safety-Focused High Voltage AC Testing
Safety is integral to the design of the KV50-200. This High Voltage AC Tester incorporates multiple layers of protection to safeguard both operators and equipment:
- Key-operated supply switch prevents unauthorised operation
- Dual overload protection with fixed and variable electronic trips
- Zero-volt interlock ensures output cannot be energised unless controls are correctly set
- External 24Vac interlock circuit for integration with test cages and emergency stops
- Visual indication of test piece failure for immediate fault recognition
In the event of insulation breakdown, the KV50-200 automatically removes the high voltage output, reducing risk and protecting the system. These features make the High Voltage AC Tester suitable for controlled test environments operating to recognised safety standards.
Built for Mobility and Industrial Use
Despite its high power capability, the KV50-200 is designed with practicality in mind. The oil-filled transformer is housed in a welded steel tank fitted with swivel castors, making positioning and relocation straightforward within the test area. A low-discharge oil-filled HV bushing ensures efficient, stable output and long service life.
This rugged construction makes the KV50-200 a reliable High Voltage AC Tester for laboratories, workshops and production facilities where durability and repeatability are essential.
