MEWOI1310B Large Caliber Wireless H/L Voltage Clamp Current Meter,High Voltage U-Type Current Meter

INTRODUCTION

MEWOI1310B Large Caliber Wireless H/L Voltage U-Type Current Meter break through the traditional structure, specially designed and manufactured for measuring high voltage current, the unique u-type opening structure realizes the unimpeded measurement, and the field test is very convenient. The meter is composed of special large-caliber U-type ammeter with high-voltage insulation rod, equipped with wireless receiver, which can receive measured data within 100 meters straight, current range: AC 0.00A-9999A. For low voltage lines below 600V, the line current can be measured directly by hook meter without insulation rod.

MEWOI1310B Large Caliber Wireless H/L Voltage U-Type Current Meteris used for current measurement of high voltage circuit below 550kV (should connect insulation rod to use). Below 600V circuit no need the insulation rod, and use the u-type current meter to measure directly.The meter has data hold and data storage function. Insulation rod is equipped with adjustable interface, u-type clamp the measured wire by insulation rod is very convenient, save time and faster. Widely used in substation, power plant, industrial and mining enterprises, detection stations, electrical maintenance departments for current detection and field electrical work etc.

It can also replace the H/L voltage turns ratio tester, which can measure the H/L voltage current of the primary circuit and secondary circuit respectively, and then calculate to get the H/L voltage turns ratio. Insulation rod is portable, with moisture-proof, high temperature resistance, impact resistance, bending resistance, high insulation, telescopic and other characteristics.
