Product Description

 

LTW 300 series 2 Wire Loop impedance testers

 The new Megger two wire earth loop testers verify the loop impedance of a live electrical circuit, ie without the need to disconnect the electrical supply. The new LTW300 series instruments offer a 2 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 - 2 Wire loop impedance measurement
 LTW325 - 2 wire + maxZ + (R1+R2)
 LTW335 - 2 wire + maxZ + (R1+R2) + Download
 LTW425 - 2 wire + maxZ + (R1+R2) + 0.001 Ω

2 Wire testing A loop test is performed with only 2 test leads.This can be either:
 Phase to Earth
 Phase to Neutral
 Phase to Phase

Testing is simple, as there is no need for a 3rd wire to be connected, which can cause confusion when trying to identify which part of the circuit is being tested. Test results are displayed to a resolution of 0.01 Ω

2 Wire Non-tripping loop tester 0.001 Ω resolution (LTW425)
50 V to 440 V operation LTW315 100V to 280V (49Hz to 50.1Hz) LTW325,335 & 425 50V to 440V (49Hz to 50.1Hz)
110 V centre-tap loop testing Display range: 0.01 Ω to 2000 Ω Accuracy: ±5% ±0.03 Ω
CATIV installation testing No-Trip loop test 15 mA (at nominal 230 V a.c supply)
AUTO start - operation E.M.C In accordance with IEC61326-1


High current loop testing 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) The LTW uses sophisticated noise detection circuitry which continually monitors the supply whilst performing a loop test to ensure the accuracy of the result has not been compromised by the effects of electrical noise from plant and services 
Two operational modes are available: a) 10 second test: Always performs a 10s test and if noise is detected displays a warning at the end of the test
