Insulation Tester FLUKE 1555

Fluke 1555 insulation tester for high voltage equipment testing

The FLUKE 1555 insulation tester is suitable for measuring voltages up to 10 kV, making it ideal for testing a wide variety of high voltage equipment including switches, motors, generators, and cables. The insulation tester meets CAT IV 600 V safety specifications, providing high safety for the user. The acquired data can be stored in internal memory or transferred to a PC via the interface. The large display allows for easy reading of values.

Features

- Checking voltages up to 10 kV 

- Electrical safety category CAT III 1000 V and CAT IV 600 V 

- The warning function alerts the user to the presence of voltage and provides the reading of the

  voltage of up to 600 V AC or DC 

- Selection of test voltages in steps of 50 V from 250 V to 1000 V, and

  steps of 100 V above 1000 V 

- The memory can store up to 99 measurements, and each one has a label

  uniquely defined by the user for ease of use 

- Long-lasting batteries allow for 750 tests per charge 

- Automatic calculation of the Dielectric Absorption Ratio and the Polarization Index without

  configuraciones adicionales 

- The measurement system with guard eliminates the effect of surface leakage in very high measurements

  resistencia 

- Large digital/analog LCD display for easy viewing 

- Measurement of capacity and leakage current 

- Ramp function for insulation breakdown tests 

- Resistance measurement up to 2 TΩ 

- Possibility of timer adjustment up to 99 minutes for scheduled checks - 3-year warranty

Electrical specifications

The accuracy of the tester has been specified for 1 year once calibrated at operating temperatures between 0 °C and 35 °C. For operating temperatures outside the range (from -20 °C to 0 °C and from 35 °C to 50 °C), add ±25% per °C, except in the bands with 20%, where you should add ±1% per °C.
