Partial discharge calibrator KAL 9511 is a successor to the popular Tettex 9216. KAL 9511 covers a wide range of applications.

It is compact, easy to use and has the same long battery operation capability of Tettex 9216 but offers higher performance by using more than 10x smaller Injection Capacitance resulting in a higher SNR (Signal to Noise Ratio).

Its unique high-end design ensures flat response of the calibration pulse in the frequency domain far beyond the IEC-recommended measuring band.

The PD calibrator is easily controlled by two large buttons. Charge values are displayed on a large display together with battery status and light synchronization indication. An SCS calibration certificate can be delivered with the KAL 9511 upon request.

Advantages
• Guarantees the reliability of the partial discharge measuring chain due to the included traceable test certificate and the optional SCS (IEC 17025) calibration certificate.
• Results reliability, plausibility, compliance and repeatability.
• Application oriented: Three different calibrator types provide sufficient charge ranges to cover all potential applications.
• Ease of use.

• Instrument transformers
• Rotating machines
• Switchgears (MV/HV/GIS)
• Surge arresters
• Bushings
• Cables (for Double Pulse see KAL 9520)
• Power capacitors
