3. Application

☆ Real Load Calibration of AC Sampling Devices (Standard Meter Method)

TD3220 supports direct measurement of three-phase voltage, ranging from 10 V to 480 V, direct measurement of three-phase current from 0.05 A to 12 A, and three-phase current clamp measurement from 0.1 A to 120 A;

Application 1 (direct current measurement)

Suitable for calibrating single-phase/three-phase voltage sources, current sources, and power sources of level 0.2 and below in the laboratory or on site.

Application 2 (Clamp measuring current)

In the past, when testing on-site AC sampling devices, it was usually necessary to wait for a power outage for maintenance before disconnecting the circuit, stringing a standard ammeter into the loop for testing, or removing the tested meter to the laboratory for testing using the standard source method.
When using a clamp meter to detect current, users can clamp the current wire into the clamp instead of cutting the circuit short, and then measure it online in real time. This instrument completes on-site inspections more quickly and conveniently, and can meet the requirements for daily inspection of the operating status of instruments.

 

☆ Real Load Calibration of AC and DC Transmitter

1. It has the secondary DC signal measurement function of the transmitter and supports a maximum DC 12V or 24 mA signal input.
2. It measures the primary/secondary signal of the transmitter running online to complete the test of basic error, output ripple, and response time.

 

☆ Real Load Calibration of CT Ratio

1. It can realize CT transformation ratio test. The instrument measures the primary signal of the CT through a large current clamp, and measures the secondary signal of the CT through a small current clamp, and calculates the CT transformation ratio and the phase relationship between the primary and secondary currents. This determines whether the CT operating status is good.
