Calibrators: Partial Discharge Equipment

KAL 450

The KAL 450 is a battery powered partial discharge calibrator for direct coupling of the generated PD signal to the test object acc. to the related standards IEC 60270 and IEEE 454. Pulse outputs ranges are 5 – 100pC. The pulse rise time is < 20ns, pulse width < 150ns. A double impulse generator with time lag of 0 – 200us monitors the superposition characteristics and resolution capability of the detector. The calibrator has a visual indication of the battery status. Triggering of the impulses is realized over external light source synchronization or by a built-in 50Hz oscillator or by an external voltage up to 400Hz/40V. The pulse phase angle can be shifted 0 – 360° in relation to the synchronization voltage.

KAL 451

The KAL 451 is a battery powered partial discharge calibrator for direct coupling of the generated PD signal to the test object according to the related standards IEC 60270 and IEEE 454. Pulse outputs ranges are 2 – 200pC and 20 – 2000pC. The pulse rise time is < 20ns. The calibrator has an acoustic indication of active operation as well as low battery. Triggering of the impulses is realized over external light source synchronization or by a built-in 50Hz oscillator.

9216

The 9216 is a small battery powered partial discharge calibrator for direct coupling of the generated PD signal to the test object according to the related standards IEC 60270 and IEEE 454. Pulse outputs ranges are 10, 102, 103, 104 pC. Triggering of the impulses is realized over external light source synchronization.
