IEC60990 Figure 4 - 1500Ω Touch Current Measurement Circuit Network for Facilitated Testing

Product Introduction

The test network adheres to the measurement network stipulations of IEC60990 for touch current and protective conductor current. Illustrated as Figure 4, it offers effortless operation and a detached power switch. This design overcomes power supply limitations of prior models, facilitating tests on high-power electrical items.


Parameter Details

  • Resistance RS: 1500Ω, crucial for current regulation and measurement precision within the network.
  • Resistance RB: 500Ω, playing a role in shaping the electrical characteristics and current pathways.
  • Capacitance CS: 0.22μF, influencing the network’s capacitive reactance and current behavior.
  • Resistance R1: 10000Ω, integral to voltage division and current control.
  • Capacitance C1: 0.022μF, impacting the network’s frequency response and filtering capabilities.

Preparation Requirements


For testing initiation, assemble an oscilloscope for waveform analysis, a voltage probe (either 1x or 10x magnification) for accurate voltage measurement, and a power supply with adjustable voltage and frequency settings to meet diverse test conditions.

Summary

The IEC60990 Figure 4 Touch Current Measuring Network is a vital tool in electrical testing. It precisely complies with relevant IEC standards for touch current and protective conductor current measurement. Its design, featuring an independent power switch and easy operation, addresses the power supply drawbacks of predecessors, enabling tests on high-power electrical products. The carefully set parameters of RS, RB, CS, R1, and C1 each contribute distinctively to regulating electrical properties like current, voltage, and frequency response. For testing, the necessary equipment combination of an oscilloscope, a proper voltage probe, and an adjustable power supply ensures comprehensive and accurate measurement capabilities across various testing scenarios.
