Portable insulation fault location systemsEDS3065/EDS3365

Function insulation fault evaluator Once the installed PGH185/183 insulation fault test device has been activated, the measuring clamps of the portable EDS165/-3 evaluator are placed around all conductors of the individual circuits (with the exception of PE). When the measuring value in a faulty subcircuit exceeds the response value, the alarm LED lights up and an audible signal sounds. The value of the test current is indicated on the display. The alarm message can be stored. Not only can current clamps be used to detect the measuring values, but also permanently installed or split-core measuring current transformers. An additional function allows measuring residual currents in earthed systems (TN/TT systems) too. The operating mode can be changed via a selector switch. Residual currents in the range of 10 mA…1 A (EDS165-3) resp. 10 mA…10 A (EDS165) can be measured. Displays The LC display indicates the measured value of the test current, the type of the connected measuring current transformers resp. current clamps, the accumulator capacity, the activation of the alarm memory, the activation of the buzzer, and the set nominal frequency. •

(during transport) 2 g/10…150 HzAmbient temperature The PGH18… insulation fault test device should be connected preferably at the power supply infeed of the system being moni-tored. Once being switched on, the PGH18... generated a defined test current signal. The existing system voltage is used to drive the test current. The test current generated in this manner de-pends on the size of the present insulation fault and the system voltage. The test current is limited to 25/2.5 mA resp. 10/1 mA, depending on the switch position and device type. The cycle of the test current is indicated via alarm LEDs.
