The LTW300 two-wire non-tripping loop impedance testers verify the loop impedance of a live electrical circuit, i.e., without the need to disconnect the electrical supply. The new LTW300 series instruments offer a two-wire loop testing solution that does not trip 30 mA RCDs and can be used on a wide range of voltages.
The new LTW300’s offer a range of features to make earth loop testing safer and easier. The range consists of:
- LTW315: two-wire loop impedance measurement
- LTW325: two-wire + maxZ + (R1+R2)
- LTW335: two-wire + maxZ + (R1+R2) + download
The LTW300 series of instruments are guaranteed not to trip working RCDs of ≥30 mA, using the no-trip loop test. Three-phase circuits with RCD protection can also be tested, as all test modes operate on single and three phase systems. The loop test runs for approximately 10 seconds, with an additional 10 seconds if the instrument detects electrical noise on the supply that could otherwise cause errors on the test result.
For supplies that do not have an RCD fitted, the high current test should be used, as there is no risk of tripping and RCD. Noise detection (only applies to no-trip tests).
