- Interlock surveillance with support for automatic door locks and required automatic earthing to prevent human hazards.
Description
The HVcontrol unit combines all standard functions required to manually operate a high voltage transformer. It includes a safety contact loop, the measurement of primary and secondary current, as well as of the primary voltage. User-settable limits for the primary and secondary current trip the main circuit breaker. The safety loop, as well as the emergency stop is hard-wired and equipped with forced contacts.
Due to its flexible design, the HVcontrol can be used on any high voltage test set. Especially, in case of the modernization of old test sets, the HVcontrol offers a multitude of improvements if compared with conventional relay-based controls.
The unit comes with rigid solid-state piezo push buttons. Each of these control buttons has an illuminated ring to indicate the state of the function controlled by this specific button. This allows an easy and intuitive operation of the HVcontrol.
The HVcontrol comes in a 19"-subrack (3HU). This makes it an easy replacement of older controls having the same size. On its rear panel, the HVcontrol offers conveniently detachable screw terminals for the different controls and optional instruments.

Frequently Asked Questions
Do I need an additional calibrated voltage meter?
Before shipment, every HVcontrol is tested and calibrated in our DAkkS-accredited in-house accredited in-house calibration laboratory to ensure that the instrument works as intended within the tolerances of international standards and in accordance with relevant regulations. The calibration process complies with the DIN EN ISO/IEC 17025 standard and is documented with the calibration certificate.
How to adapt the HVcontrol to my test set?
Each HVcontrol comes with customized inputs for primary current, primary voltage and secondary current. Besides this the interlock signal in mandatory. The also required automated earthing unit can be retro-fitted – other feedback signals are optional. For a full list please refer to the manual. All outgoing contacts for closing relays, driving up and down are potential free contacts.
What is the advantage of the HVcontrol compared to other solutions?
The STEP option of the HVcontrol together with the HVpilot software allows to specify detailed voltage curves. Within the HVpilot software these voltage curves can be used to create individual test profiles for PD and/or TanDelta testing including result interpretation using an ICMcompact, resp.a TDAcompact.
