Digital Residual Current Devices Tester, RCD Types A, AC
Residual current circuit breakers are used for personal protection and switch off a circuit when a fault current is detected, which flows through the protective earthing (PE). This RCD tester determines the tripping current and the tripping time of residual current circuit breakers which are used in every new building according to current building regulations.
The various selectable test currents and characteristics of the RCD allow flexible use of this instrument. RCD testers allow a fault current to flow and determine at which fault current the RCD reacts. Furthermore, the trip time is measured. These two parameters tripping current and tripping time are the safety-relevant characteristics of a residual-current-operated...
Loop/PSC Digital Tester
PeakTech 2715 Loop/PSC Digital Tester takes two measurements: "LOOP" and "PSC".
The "LOOP" function measures the impedance of the circuit between the phase and the earth conductors. If there is a RCD in the circuit, the "LOOP" function can trip it. To limit the test current to 15 mA and prevent the RCD from tripping, use the 2,000 Ω range.
A low earth impedance ensures a small contact voltage Uc in the event of a fault.
The "PSC" function measures the prospective short-circuit current (PSC) between the phase and the neutral conductors in the event of a short between the two.
Knowledge of the PSC allows you to choose the circuit breaker so that it has a breaking capacity higher than the PSC.
Electrical Installation Safety Tester with TFT-Color Display, SD-Card, USB, Bluetooth - According to VDE 0100
This innovative combined meter for testing electrical installations has technical performance in the high-end range. With the large 3.5 "TFT color display all important safety checks as the RCD, Voltage, Loop, Low-Ohm, Earth resistance and Insulation tests for annual safety-checks and newly installed systems can safely be carried out by the responsible electrical engineer. Since this new development was designed only according to the latest standards, the required measuring values can be even more conveniently stored with an App (iOS/Android) via Bluetooth on the mobile phone, saved to SD card or, when work is completed, from the internal data memory via USB connection to PC.
