Monitoring of HV Apparatus Insulation

Features ● Measuring frequency: DC, 50Hz~400Hz ● responding time: 350ms ● Linearity: 0.5% ● No measurement insertion loss ● Measuring AC or DC current, output DC standard signal ● High isolation between the primary current and secondary output signal ● Nice appearance, waterproof paint surface treatment, directly suitable for outdoor installation ● Low consumption of power supply, single power supply is suitable and wider supply range. Applications Suitable for the signal

Features ● Cross core design, convenient installation, safe and reliable ● Metal case design, strong anti interference capability, suitable for indoor and outdoor environment ● High sensitivity design, high accuracy, good linearity ● Passive and active series are optional. ● Nice appearance, waterproof paint surface treatment, suitable for outdoor using. Applications ● Used for high voltage electrical equipment on-line insulation monitoring devices of transformer substation,

Features ● Center hole-through, easy installation,on the safe side. ● Metal casing,better capacity of resisting outside surroundings. ● High-sensitivity/accuracy,good linearity. ● Two series for selection: passive and active Applications ● Used in high voltage electric power equipment insulation monitoring plant, which is stalled in transformers station.Provide exact measurement for mA leakage current of high voltage power equipment, such as transformers sleeve, current
