SPECIFICATIONS
• Center hole-through, easy installation,on the safe side. • Metal casing,better capacity of resisting disturbance,be adequate for inside and outside surroundings. • High-sensitivity/accuracy,good linearity. • Two series for selection: passive and active
• 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 transformers
• Frequency：50Hz • Rated current：10mA、20mA、30mA • Measuring range：0.5～700mA • Output signal：mV／mA • Amplitude error：±0.1% • Phase error：±1' • Environmental temperature：一30º C～+75º C Influence on phase error by temperature change is＜1’ • Diameter of primary center hole：Φ13mm, 25mm, 40mm, 50mm
