35kV Power Cables AC Hipot Tester 0.01Hz High Voltage VLF Hipot Instruments
Product Description
35kV Power Cables AC Hipot Tester 0.01Hz High Voltage VLF Hipot Instruments
Introduction
High Voltage VLF Hipot Instrument combines the advanced technology of modern digital conversion, fully computer control, automated boost, buck, measurement and protection.
High Voltage VLF Hipot Instruments has the characteristics of stable output voltage, high testing efficiency, and good safety, and is widely used in fields such as power, energy, and manufacturing to ensure the reliability and safety of equipment during long-term operation.
Regarding 35KV cable test, should be single-phase test, voltage is set as 60KV(conventional requirements) -78kV (according to the requirements of the regulation), frequency is set as 0.1Hz(recommended), 0.05Hz(recommended), 0.02Hz(the process of voltage boost is slow), 0.01Hz(the process of voltage boost is slow, 10-40 minutes, Suitable for cables of more than 10 km), the carrying capacity mentioned in the manual is the theoretical value, and the length of 35KV cable can reach 3-15 km on site.
How to choose the appropriate rated voltage?
1. Kindly make sure that the capacitance of test products is below the instrument rated capacitance.
2. Kindly provide the voltage level of your power cables to us.
3. Kindly tell us the length of your power cables.
