August 2010Maintenance, Test & Measurement, Calibration
Comtest Technologies has announced the redesigned Fluke 1555 and 1550C insulation resistance testers. The new instruments 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, 3-year warranty and CAT IV 600 V safety rating. With measurement storage and PC interface, the 1555 and 1550C are ideal tools for preventative or predictive maintenance programs designed to identify potential equipment failures before they occur. Features include:
* Selectable test voltages in 50 V steps from 250 to 1000 V, and 100 V steps above this.
* Measurements can be stored in up to 99 memory locations, with each location assigned a unique, user defined, label for easy recall.
* Long battery life gives the user over 750 tests between charges.
* Automatic calculation of dielectric absorption (DAR) and polarisation index (PI) with no additional setup.
* Guard system eliminates the effect of surface leakage current on high-resistance measurements.
