Fluke 1550C 5 kV Digital Insulation Tester

Description

Fluke 1550C 5 kV Digital Insulation Tester

The Fluke 1550C insulation resistance tester offers digital insulation testing up to 5 kV, making them ideal for testing a wide range of high voltage equipment including switchgear, motors, generators and cables.

Fluke insulation testers can now conduct the entire range of test voltages specified in IEEE 43-2000 with a best in class and CAT IV 600 V safety rating. With measurement storage and PC interface, the 1550C is the perfect tool for preventative or predictive maintenance programs designed to identify potential equipment failures before they occur.

Fluke 1550C 5 kV Digital Insulation Tester

• Features include:

  • Test voltages to up 5 kV and save time by trending on the spot only with Fluke Connect™

  • Timer settings up to 99 minutes for timed tests

   

• Electrical Specifications
  The tester’s accuracy is specified for one year after calibration at operating temperatures of 0°C to 35°C. For operating temperatures outside the range (-20°C to 0°C and 35°C to 50°C), add ± .25% per °C, except on the 20% bands add ± 1% per °C.
