Product Detailed
Partial discharge instrument TCD-9302 is a new-type developed apparatus, it is as IEC 270.  

1. Capacitance range to be tested: 6pF~250uF

2. Detection sensitivity and allowable current (see Table 1)

3. Elliptical sweep time base

(1) Frequencies50100150200400z.

(2) Rotation: rotating in 120owith 30o each.

(3) Operation mode: standardextensionstraight line.

(4) Input voltage range at the high frequency time-base ellipsoid: 13~275V.

4. Display unit

Adopting 100*80mm rectangle oscilloscope tube, with brightness control and focusing control knob.

5. Amplifier

(1) Frequency on 3dB low frequency, fL side: 20, 40KHz is optional.

(2) Frequency on 3dB high frequency side, fH: 200, 300KHz is optional.

(3) Gain adjustment: 6 shelves coarse adjustment, gain ratio between bands: 10 times of ± 5%.

(4)Fine adjustment range: >10 times.

(5) Asymmetrical distortion in positive and negative pulse response5%.

6. Time window
