Ⅳ: Features About The DC Hipot Cable Test:
1. Dc high voltage generator adopts high frequency PWM technology to make closed adjustment with high voltage stability, small ripple factor and fast reliable protection circuit. The generator can endure direct discharge by devices of large capacitance. It is of small size and of light weight, convenient for field use.
2. Over-voltage setting function displays the over-voltage value during regulation process; perfect protection against discharge of over-voltage, over-current and short circuit. This is the best companion for cable experiments.
3. Perfect break line and non-zero potential start protection function protects the operator and samples at any time. This product has overall design of shock-proof control box, concise, clear panel design and voice prompt for operation.
4. 75% MOA voltage switch button, simple and convenient testing arrester.
Ⅴ: Pay Attention for this Hipot Test Equipment:
1. Do not overload operation, not too fast lift pressure, continuous use time should not exceed 30 minutes.
2. If the subject is a cable, it needs to know the voltage level to determine the voltage and the cable length to determine the current.
3. When measuring lightning arrester, use microammeter to connect the cylinder high pressure line.
