 Product Details UNIT UT255A High-Pressure Clamp Ammeter to break through the traditional structure, designed for the online measurement of high voltage transmission line current, leakage current to determine the operation of the MOA. The latest CT and shielding technology with high voltage insulation rod composed by a dedicated high-voltage detector. Without the use of insulated rods, can also be used as a precision low-voltage clamp leakage current meter, ammeter, can accurately measure the 0.01mA leakage current or current. If the focus for a very small leakage current or current testing, and the best selection of wireless transmission type, to facilitate the timely display.
UNIT series of high pressure clamp meter can be changed as the high and low voltage current transformer ratio tester, zinc oxide arrester tester. Ie, the current transformer secondary circuit current were measured, calculated to draw the change of the current transformer ratio or rate ratio. Note: put into operation the arrester leakage current less than 500uA leakage of the test arrester to determine the operation of the arrester, measured arrester leakage current is too large, more than 500uA, which excludes the system voltage is too high, then the arrester may have stains or moisture or aging, the greater the leakage current, stains or moisture or aging of the more serious.
UNIT series of high-pressure clamp ammeter connected insulating rod can be used for less than 60kV high-voltage line leakage current measurement, the line current measurements to determine the zinc oxide arrester whether damp or bad run, the instrument also has a peak hold, data retention, data storage, wireless transmission function, its special high-voltage clamp by pressing or pulling back the insulating rod can easily clamp or withdrawal of the conductor under test, time-saving shortcut, widely used in substations, power plants, industrial and mining enterprises as well as testing stations, electrical maintenance department for leakage testing and field electrical operations and so forth.
UNIT series of high-pressure clamp ammeter clamp and innovative integrated design of the boot sector, ensuring all year round without interruption test accuracy, high reliability and high stability. Insulating rod is lightweight, moisture, high temperature resistance, impact resistance, bending resistance, high insulation, and scalable.
