  • Page 85: Charge Resistors For Automated Ir Testing

    6.5 Charge Resistors for Automated IR Testing Scope Automated testing of capacitor insulation resistance (IR) with TH2684/TH2684A IR tester often requires a stepwise charging of the capacitor before the acutual resistance measurement. This could be due to the fact that the charging time is longer than the time between measurements or to secondary effects like post charging (“dielectric absorption”) of foil capacitors.
  • Page 86 The fine charge reistors should match the input resistance Ri of the current input amplifier. In TH2684/TH2684A IR tester, this resistor can be switched to either 10kΩ or 1MΩ. In figure 6.5.1 only two fine charge stations are shown, in many cases more than 10 stations are preferred.
  • Page 87 Wiring and installation in sorting machine When installing the TH2684/TH2684A IR tester and charge reistors in sorting machines, great care should be taken in the wiring.

  • Page 88 TH2684/A Operation Manual Chapter 6 Measurement Procedures and Examples Figure 6.5.2 Wiring of sorting machine The precharge stations are supplied from HV2. The return path of the charge current must be the HV2 return and each precharge station must have its own return wire. In this way it is possible to ensure parallel wiring of the complete path from tester to each precharge station.

    This also minimizes influence between measuring equipment, computers motor controls, etc. 6.6 Insulation resistance measurement Scope When measuring Insulation Resistance (IR) with TH2684/TH2684A, there are several issues to consider when comparing to resistance measurement with a common multimeter. This application note is intended to address some of these.

Connecting TH2684/TH2684A series Insulation Resistance Tester When connecting the TH2684/TH2684A to the DUT, there are few issues to address to ensure safety, noise free measurement, and minimum disturbance of the surroundings and long term stability of the instrument.
