The Kewtech KT66DL and KEWEVSE testing adapter for the testing of EV charging points provides a comprehensive kit for those with electrical vehicle charging points. Whether these are installed with Type B RCDs or with 6mA residual direct current devices and in either TN or TT configurations, this kit gives you the flexibility to test for electrical safety as well as EVSE functionality.
The KT66DL has an easy-to-use single rotary dial with four function softkeys and a colour LCD 3.5” dot matrix display. It also incorporates Anti-Trip Technology (ATT) which electronically bypasses RCDs when performing loop impedance tests. This saves time and money by not having to take the RCD out of the circuit during testing and is a safer procedure to follow.
The KT66DL Multi-function tester has eight test functions in one tester.
1. Continuity test.
2. Insulation resistance test.
3. Loop impedance test (High current measurement, No trip (ATT) measurement).
4. Prospective short circuit current test (On Loop impedance function).
5. RCD test.
6. Voltage test.
7. Phase rotation test.
8. Earth test.
The KT66DL incorporates Anti Trip Technology (ATT) which electronically by-passes RCDs when performing loop impedance tests. This saves time and money by not having to take the RCD out of the circuit during testing and is a safer procedure to follow.
With the ATT function enabled, a test of 15mA or less is applied between line & earth. It enables loop impedance measurements without tripping RCDs rated at 30mA and above. ATT supports measurements using three wires: Line, Earth, and Neutral and also two
wires: Line and Earth.
