Megger LTW315-RS-BS Loop Impedance Teste

LTW 300 Series Earth loop impedance testers to verify the loop impedance of a live electrical circuit without the need to disconnect the electrical supply. The LTW300 series instruments offer a safe and easy 2 wire loop testing solution that does not trip 30mA RCDs and can be used on a wide range of voltages. Backlit display 0.01Ω resolution No-trip loop test on circuits with RCDs of ≥30 mA 3 phase circuits with RCD protection can be tested Tests radial circuits where the circuit does not return to the origin, even where only a phase and neutral contacts are available. 10 second non trip loop test time with Auto test extension up to a further 10 seconds if noise is detected, to improve the accuracy of the test High current loop testing for supplies that do not have an RCD fitted AUTO START will start the loop test running as soon as the test leads are connected; no need to press the test button means much safer testing PFC Display up to 20kA Voltage and frequency measurement 110Vac systems including 110V centre tap to earth (55V phase to earth) can be tested on the secondary winding. IP54 Weatherproof case Optional 10A fused 2 wired test leads and crocodile clip set Complies with IEC61010-1 300V CATIV safety standard and meets EN61557 Voltage measurement (ac only) 50V to 440V Accuracy ±2% ±1V Range 25Hz to 99.99Hz Accuracy ±0.1Hz A warning will be shown if applied voltage exceeds 440V Damage will occur if applied voltage exceeds 600Vrms Loop testing No-trip loop and high current loop test Source voltage LTW315: 100V to 280V (50Hz) LTW325: 50V to 440V (50Hz) Display range 0.01Ω to 2000Ω Accuracy ±5% ±0.03Ω Nominal test current No-Trip loop test 15 mA (at nominal 230Vac supply) High current loop test 4 A (at nominal 230 Vac supply) Operational range 0.30Ω to 1000Ω Prospective Fault Current (PFC) Prospective fault current Measured Source Voltage / Loop resistance Maximum range 40 kA; accuracy is derived from loop test and voltage measurement.
