Insulation resistance testing A complete solution— for every application.
Why perform insulation testing? Safety Equipment uptime The most important reason for testing insulation is to ensure public and personal safety. By performing a high dc voltage test between de-energized current-carrying (hot), grounded, and grounding conductors, you can eliminate the possibility of having a life-threatening short circuit or short to ground which could lead to a fire. In addition, insulation testing is important to protect and prolong the life of electrical systems and motors.
The International Electrical Testing Association (NETA) also provides recommended test voltages when manufacturer’s data is not available: Nominal voltage rating of equipment Minimum insulation resistance dc test voltage Recommended minimum insulation resistance in megohms 250 500 25 600 1,000 100 1,000 1,000 100 5,000 2,500 1,000 15,000 2,500 5,000 Recommended test voltages and minimum insulation values.
Insulation spot test This can be used to verify the condition of the insulation over the life of a motor by connecting Megohmeter to measure resistance of each winding to ground while recording reading onto graph. Insulation step voltage Creates electrical stress on internal insulation cracks to reveal aging or damage not found during other motor insulation tests. This test is done by testing the insulation at two or more voltages and comparing the results.
Insulation resistance The latest test tools from the testing experts. Time and again, electrical workers tell us about the importance of testing insulation resistance. Insulation resistance tools are critical to a preventative maintenance program, and a staple for troubleshooting any number of utility, industrial and commercial applications. “You asked. We responded. Now you have more insulation testing choices than ever.
A digital insulation tester and full-featured multimeter— TWO TOOLS IN ONE! Fluke 1587 FC/1577 Insulation Multimeters The Fluke 1587 FC and 1577 combine the features of an insulation tester with a full featured multimeter in one, compact product. Both offer the “two tools in one” feature set, combining a digital insulation tester with a full-featured, true-rms digital multimeter in a single, compact, handheld unit. The result: maximum versatility for both troubleshooting and preventative maintenance.
Key features • Insulation test 1587 FC: 0.01 MW to 2 GW 1577: 0.
Insulation resistance testing in the palm of your hand Fluke 1507/1503 Insulation Resistance Testers With their multiple test voltages, the compact Fluke 1507 and 1503 Insulation Testers are ideal for many troubleshooting, commissioning, and preventative maintenance applications. Additional features, like the remote probe on these tools, reduces the time needed to perform repetitive testing.
Digital insulation testing up to 10 kV Fluke 1555/1550C Insulation Resistance Testers The new 1555 and redesigned Fluke 1550C insulation resistance testers, offer digital insulation testing up to 10 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, three-year warranty and CAT IV 600 V safety rating.
Fluke has created combo kits to help maximize your productivity and help you solve problems faster and reduce downtime, all with significant savings over buying each product individually. The products in each kit have been specifically selected for both troubleshooting and preventative maintenance applications. Establishing preventative maintenance programs are becoming critical to maintaining the uptime of electrical equipment and can significantly reduce both planned and unplanned downtime.
