Very-low frequency High Voltage Test Set

Description:

• For those bigger capacitance specimens, such as *5KV XLPE power cable, Generators, Power Capacitors, their HV dielectric strength test at main power frequency, Very Low Frequency is an idea substitute.
• Compared with Hipot test set at main power frequency, VLF HV Test Set need much small test power capacity. About 1/**0 in theory. Its size and weight also is decreased greatly.
• Based on electronic frequency conversion and microprocessor controlled technology, Model VLF*0KV /1.1uf has excellent performance.
• For VLF*0KV/1.1uF,it is prohibited to boost voltage without load, or to connect with resistive load.  

Product Features:

• Electronic frequency conversion        
• Microprocessor Controlled
• Portable design, Large LCD display
• Sine Wave Output
• Overvoltage protection, action time is less than*0ms
• Over current protection for both and output side, action time is less than*0ms
• Output current/Voltage\wave form is sampled at high voltage side directly
• HV Current Limiting Resistor inside
• Micro-printer inside
• Output voltage will not be affected by capacitive current during test since closed-loop negative feedback design
