Very Low Frequency Tester -- Model VLF

Introduction:

• VLF Very Low Frequency 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.

Features:

• 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;
