Product Description

80KV Very Low Frequency AC Hipot Tester for Power Cable





Introduction:

• VLF Tester is designed and manufactured for electrical equipment very low frequency withstand voltage test.

• Very low frequency withstand voltage test is essentially an alternative of power frequency withstand voltage test. It is much smaller, lighter and portable than power frequency withstand voltage tester. It is proved home and abroad that 0.1Hz ultra-low frequency withstand voltage test can replace power frequency withstand voltage test.

• It can be applied for 10kV, 35kV, 300MW thermal power machine, 10kV, 35kV power transformer and other electrical equipment

Specification:

• Max voltage output: refer to following table;

• Output frequency: 0.1Hz, 0.05Hz, 0.02Hz;

• Measurement accuracy: 2.5%;

• Positive and negative voltage peak errors < 2.5%RDG+0.3%FS;

• Voltage wave form distortion:<3%;

• Insulation resistance measurement error:<2.5%;

• Leakage current measurement error:<2.5%;

• Power supply:AC220V ± 10%, 50Hz/60Hz;

• Environment temperature: 0~50°C;

• Humidity:≤85%RH;
