A DC resistance tester applies a controlled DC current and measures the resulting voltage to determine resistance. Proper wiring, discharge handling, and current selection support a stable measurement process.

Noise can reduce detection sensitivity or generate signals that may be mistaken for discharges occurring within the test specimen. This article examines common noise sources, noise coupling paths, and key considerations when evaluating partial discharge test results.

Chroma has integrated Rohde & Schwarz MXO oscilloscope hardware into its ATS 8000 automated test platform. The integration expands waveform measurement and analysis capabilities for testing power conversion devices, meeting the increasingly demanding requirements of high-power supplies and power systems used in data centers.

A practical guide to safer partial discharge detection system setup, focused on grounding, warm-up, interference reduction, calibration, and connection handling.

A switch parameter tester helps maintenance teams evaluate switching behavior in circuit breakers, isolating switches, and related switchgear. This guide explains its role, typical test workflow, data considerations, and selection factors.

A practical introduction to low-voltage phase testing, including its purpose, factors that influence readings, selection considerations, and essential safety practices.

A practical guide to interpreting dielectric constant and dielectric loss when evaluating electrical insulation materials and planning reliable test conditions.

An SF6 dew point meter helps monitor the moisture content of SF6 gas, supporting the development of appropriate inspection and maintenance plans for high-voltage electrical equipment. The operating procedure involves more than simply connecting the instrument and pressing the measurement button. Gas sample quality, the condition of the sampling line, and the way the test is completed can all affect the measurement results.

Measuring trace moisture in SF6 gas helps technical teams assess operating conditions and develop maintenance plans based on changing trends. This is why SF6 moisture analyzers are commonly used during routine inspections, after maintenance, or whenever the condition of the gas inside electrical equipment needs to be reassessed.

SF6 gas analyzers help identify and assess SF6 gas leakage, supporting the maintenance of high-voltage electrical equipment and more efficient gas management. In addition to measurement parameters and accuracy, it is also necessary to consider how the gas enters the instrument, how it is analyzed, and how it is handled after the measurement.
