Frequency voltage test equipment is usually comprised of test transformer and control panel. Features of control panel: - Supervising function: Can supervise output current, instrument voltage, zero indication, power indication, working indication, timing indication, etc. - Protection function: Over-current protection - New pattern time relay, wider timing range - New pattern current relay, more accurate and reliable - Compact structure and light Specifications of control panel - Input voltage: 220V± 10% 50Hz - Output voltage: 0~250(430)V - Output capacity: 0~5KVA - Timing range: 1S~99H - Ambient temperature: -20 degree ~ 50 degree Description of test transformer: Test transformer is also called step-up transformer, for insulation strength testing on various kind of electric apparatus, elements and insulation materials, checking their insulation level and over-voltage capability.
