Application of Three Channel DC Resistance Tester

:2025-03-18 09:38:13:

The three channel DC resistance tester is a precision instrument that can simultaneously measure the resistance values of three channels, and is widely used in various fields such as power, electronics, and scientific research. Its core value lies in synchronous measurement, efficiency improvement, and comprehensive analysis. The following is a detailed introduction for you:

1. Core functions and advantages

① Synchronous measurement

It can simultaneously test three independent circuits (such as three-phase windings of transformers) to avoid errors caused by environmental or temperature changes in segmented measurements and ensure data consistency.

② Efficiency improvement

Time reduction: Traditional single channel testing requires phase by phase measurement, while three channel instruments can be completed in one go, increasing efficiency by 300%.

Simplified operation: Automatically calculate the resistance imbalance rate, reduce manual calculation steps, and lower operational complexity.

③ Accurate diagnosis

Supports high-precision measurement with low resistance values (such as milliohms), suitable for detecting subtle issues such as winding contact and wire connections.

④ Extended functionality

Data storage: Built in large capacity storage, supporting historical data retrospective analysis.

Protection mechanism: equipped with power-off protection, disconnection alarm and other functions to ensure testing safety.

2. Main applications

① Transformer detection

Synchronously measure the DC resistance of three-phase windings to quickly identify issues such as inter turn short circuits and poor contacts. For example, in the preventive testing of 110kV substations, the three channel instrument can shorten the detection time and support the rapid operation of transformers.

② Generator maintenance

Synchronize testing of different parts of the rotor winding to detect resistance abnormalities caused by overheating or wear, and prevent faults.

③ High voltage switch test

Measure the contact resistance of three-phase contacts, evaluate the conductivity, and avoid heating of switches due to excessive resistance.

④ Maintenance of transmission lines

Check the resistance of the circuit joints to prevent overheating or disconnection of the joints.

summarize

The three channel DC resistance tester significantly improves the efficiency of resistance testing through synchronous measurement technology. Its high precision and extended functionality make it irreplaceable in power maintenance, electronic manufacturing, and scientific research experiments. For scenarios that require batch testing or three-phase equipment inspection, this instrument is an ideal choice to improve work efficiency and testing accuracy.
