MEWOI1330B Large Caliber H/L Voltage Hook type Current Meter


     MEWOI1330B Large Caliber Wireless H/L Voltage Clamp Current Meter break through the traditional structure, specially designed and manufactured for measuring high voltage current, the unique U-type opening mouth structure realizes the unimpeded measurement, and very convenient for field test. The meter is composed of special large-caliber U-type current meter with high voltage insulation rod, equipped with wireless receiver, which can receive the measured data within 100 meters straight line distance.

      MEWOI1330B Large Caliber Wireless H/L Voltage Clamp Current Meter used for current measurement of high voltage line below 500kV (connect insulation rod to use), current range: AC 0.00A-9999A, it can directly to test with U-type crrent meter without the insulation rod below 600V. The meter has data hold and data storage and other functions. Insulation rod is equipped with adjustable interface, U-type clamp the tested wire by insulation rod is very convenient, save time and faster. It also can replace the H/L voltage transformation ratio tester, which can measure the H/L voltage current of the primary circuit and the secondary circuit respectively, and then calculate the H/L voltage transformation ratio. The insulation rod is handiness, and has the characteristics of moisture-proof, high temperature resistance, impact resistance, bending resistance, high insulation, scalable and so on.


 CT Size Ф128mm
 Sampling Rate 2 time/second
 Measurement Range 0.00mA~9999A(50/60Hz automatic)
 Resolution 0.01A
 Shift 0.00A~9999A automatic shift
 Test Accuracy ±2%±5dgt (The wire is near the center of the topof the hooktype clamp,23℃±2℃)
 Position Error The measured conductor should be located as close as possible to the center of the top of the hooktype clamp. it can hung on the line directly for measurement.Test errors increase one more times or more when away from the top of the hook clamp
 Data Storage 99 groups, in storage process “MEM” symbol display, “FULL” symbol flash display indicate storage is full
 Line Voltage  Below 110kV current test , operate with insulation rods ( below 500kV can be customized )
 Data Hold In general test mode, press HOLD key to hold data, “HOLD” symbol display. press HOLD Key once again to cancel this function
 Data Access “MR” symbol display, it can look over all the stored data
 Overflow Display Exceed measurement range overflow function: “OL A” symbol display
 No Signal Indication When the receiver has not received transmit signal, dynamic display “no- -”symbol.
 Automatic Shutdown 15 minutes after boot up, the meter shuts down automatically without any operation, to reduce battery consumption 
 Battery Voltage When battery voltage is lower than 4.8V, low battery voltage symbol  will display and remind to replace battery.
