Vlf 34kv High Power Sine Wave Vlf System Vlf Sine 34 Kv TesterIntroduction:Vlf Sine Wave Vlf System Vlf Sine Tester is designed and manufactured for electrical equipment very low frequency withstand voltage test. Vlf Sine Wave Vlf System Vlf Sine Tester 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;
