TD1000 Calibration Device for Clamp Ammeters

专用于校准交流钳形电流表

参考标准:JJF 1075-2015《钳形电流表校准规范》( 天恒测控参与起草 )


准确度为 0.05 级 / 0。1 级可选

单匝法直接输出 1100 A 的大电流


Overview

Model TD1000, a calibration device for clamp ammeters. The optional accuracy classes are 0.05 and 0.1. The device calibrates the AC clamp ammeters by single coil, and has the functions of AC current output and resistance simulation. It also can be applied to calibrate the voltage and resistance of AC voltmeters, ohmmeters and multi-function clamp meters.

Meet the requirements of JJF 1075-2015 Calibration Specification for Clamp Ammeter。 (Tunkia is involved in drafting)

Features

Calibrate AC clamp ammeters by single coil: The AC current source connects to a single coil semi-circular copper ring with a diameter of 1m, can directly output AC high current up to 1100 A.

● Suitable for calibrating AC clamp ammeters with medium to high accuracy.

● Place the clamp meter in the center of the copper ring when calibrating. The diameter of the copper bar in the center position is smaller than the other positions, which is convenient for the access of small size clamp meters.

● Easy to open the copper ring, and thread a standard current transformer or I-V converter into the ring for calibrating the device itself regularly.

● The current output has the characteristics of high accuracy, good stability, small waveform distortion and high power.

● Equipped with the nonmagnetic worktable, and the display-operation panel is placed on the worktable for a fast calibration.

● Value Adjustment Method: Fixed-point, rotary encoder, and step.

● Proprietary Software (Option): Support the calibration of the checked ammeters by semi-automatic or full-automatic, data management and report export.
