Testing resistance.

Two portable and lightweight (1.3 kg) Insulation Resistance Testers for fast, accurate and reliable testing up to 2500 V (DC) have been announced by Fluke.

The high-voltage 1535 and 1537 Insulation Resistance Testers are ideal for industrial electricians, maintenance technicians, electrical engineers and field service engineers looking to simplify frontline troubleshooting and improve productivity. Whether used on the factory floor or in the field at a solar PV installation, for maintenance work on such equipment as motors, transformers or power cabinets, the insulation testers deliver equally rapid and stable resistance measurements and enable users to cover greater workloads with a single tool.

A full portfolio.
Completing the tester range from Fluke in this sector, the 1535 and 1537 Insulation Resistance Testers are capable of taking up to 6500 measurements at 250 V or 1300 measurements at 2500 V with one set of batteries, giving the user complete control. For greater flexibility, test voltages are user selectable and adjustable, and a ramp function is available, which is ideal for industrial or solar PV applications. Resistance measurements can also be taken up to 500 GΩ, whether working on small circuits or high-voltage systems, while the 1537 Insulation Resistance Tester enables measurements to be stored for later review or PC transfer using the Fluke software provided.

Both testers are user-friendly with intuitive user interfaces. The Fluke 1537 has a high short circuit current of up to 5 mA and both testers have enhanced safety rating through CAT IV 600 V and built-in voltage alarm function. At the same time, both units comply with the standard series IEC 61557 and IEC 61010 for safety and IEC 61326-1 for electromagnetic compatibility. Furthermore, Automatic Polarization Index (PI) and Dielectric Absorption Ratio (DAR) calculation means influence of environmental factors on insulation performance can be minimised without the need for additional set-up.

Hans-Dieter Schuessele, Application & Technology Expert and Standardization Manager EMEA, Fluke says: “With these high-voltage 1535 and 1537 Insulation Resistance Testers, operators now only need to use a single device to test a wider range of applications than before in the knowledge that they will always get rapid, stable and reliable results. The new testers put the user in control when carrying out vital maintenance work, whether in industrial and solar PV applications, and help to improve the productivity of electricians and contractors through a range of valuable features.”

Insulation multimeter.

Fluke has introduced the Fluke® 1587 FC Insulation Multimeter, a high performance wireless digital insulation tester plus full-featured true-rms digital multimeter (DMM) combined into one versatile handheld tool. The wireless Fluke 1587 FC provides enhanced versatility for both troubleshooting and preventive maintenance applications.

As part of Fluke Connect®, the industry’s largest system of software and more than 30 wireless test tools, the 1587 FC adds four powerful new diagnostic capabilities when used in conjunction with the Fluke Connect smartphone app:

• PI/DAR (polarity index/dielectric absorption ratio) with TrendIt™ graphs identifies moisture and contamination problems faster
• Memory storage through the mobile Fluke Connect app reduces errors by eliminating the need to write down results, and saves data to the Fluke Cloud™ for historical tracking over time
• Temperature Compensation through Fluke Connect app helps establish accurate baselines and relevant historical comparisons
• Historical tracking and trending of assets using the Fluke Connect® Assets software identifies degradation over time, allowing real-time decisions in the field.

The CAT III 1000V / CAT IV 600V safety-rated Fluke 1587 FC features a VFD low-pass filter for accurate motor drive measurements, insulation tests of 0.01 MΩ to 2 GΩ, and insulation test voltages of 50, 100, 250, 500, and 1000V. It also includes user safety features like auto-discharge of capacitive voltage and live circuit detection that prevents insulation tests if voltage greater than 30V is measured on the unit under test.

Technicians can use the 1587 FC in conjunction with the free Fluke Connect app to record and store measurements, then combine measurement data from multiple Fluke Connect test tools to create and share reports from the job site via email and collaborate in real time with other colleagues with ShareLive™ video calls, increasing productivity in the field.*

10kV insulation testers

Fluke has introduced two insulation resistance testers offering digital insulation testing up to 10kV for testing a wide range of high voltage equipment including switchgear, motors, generators, transformers and cables. The new Fluke 1555 and redesigned Fluke 1550C Insulation Resistance Testers enable users to conduct tests over a wide range of voltages with a best-in-class 3-year warranty and CAT IV 600V safety rating. With their measurement storage and PC interface capabilities, they are the ideal tools for engineers, maintenance managers, industrial electricians, sub-station specialists and linemen using predictive and preventive maintenance programmes designed to identify potential equipment failures before they occur.

The Fluke 1550C Insulation Resistance Tester enables testing up to 5kV, while the Fluke 1555 tests up to 10kV. Test voltages are selectable in 50V steps from 250V to 1000V, then 100V steps thereafter. A ramp function enables breakdown testing, and timer settings of up to 99 minutes allow timed tests. A warning voltage function alerts the user that line voltage is present and gives the voltage reading up to 600V AC or DC for increased user safety.

Measurements can be stored in up to 99 memory locations. Each location is assigned a unique, user-defined label for easy recall. An optical interface cable enables easy downloading to a PC running the FlukeView® Forms software that is provided with the insulation tester. FlukeView Forms allows the user to document, store and analyse the readings, and present them in professional-looking documents.
Both feature a large digital/analogue LCD display for easy viewing. They provide automatic calculation of Dielectric Absorption Ratio (DAR) and Polarisation Index (PI) without additional setup. They also offer capacitance and leakage current measurement, as well as resistance readings up to 2T Ohms. A guard system eliminates the effect of surface leakage current on high resistance measurements.

Kit versions are also available which offer an IP67 hard case, heavy duty alligator clips and a calibration certificate.

Insulation testers reduced

Fluke, the global leader in handheld electronic test and measurement equipment, has reduced the prices of all its Fluke 1650B Series of multifunction Installation Testers, designed to test and verify domestic, commercial and industrial electrical installations. With more features than the earlier 1650 Series, the Fluke 1650B testers ensure that fixed wiring is safe and correctly installed to meet the BS7671 17th Edition wiring regulations as well as IEC 60364 and HD 384. The Fluke 1652B/PKit Electricians Kit is also reduced in price.

The Fluke 1653B is the complete tester for virtually all electrical wiring installations, for domestic, commercial and industrial use. It is equipped with a built-in memory to store test results fast and easily on site: the data can be uploaded later to a computer for the preparation of professional reports. The 1652B is the ideal tester for the professional working in domestic and commercial installations. The Fluke 1651B is the everyday tester, ideal for domestic installations covering all the basic needs for testing the 17th Edition wiring regulations / Part P of the building regulations.

The Fluke 1652B/PKit Electricians Kit is a complete solution to testing and verifying domestic and commercial electrical installations. It comprises the Fluke 1652B; a Fluke T120 2-pole Tester, which features an LCD display and LED bargraph to indicate voltages from 12V to 690V AC/DC and a patented three-phase rotation detection system; and a Fluke SM200 Socket Tester, with 3 vivid bi-colour LEDs and an audible buzzer which indicate missing earth, live/earth reverse, live/neutral reverse, missing neutral or live faults.

The Fluke 1650B Series show two measurements at once on a dual display. This can show PEFC/PSC and loop impedance results in parallel negating the requirement to run the tests separately, more than halving the test time of other loop testers. The 1650B Series also features a high-current loop test which gives extremely fast measurements when testing in circuits where no RCDs are being used. All models offer both non trip and the high current test so the user can select depending on the application. In addition there is fast voltage measurement between L-N, L-PE and N-PE using the mains cord, with no need to change measurement connections.

For ease of use, a rotary dial clearly indicates which function is selected, and provides access to all functions in one place to avoid complex multi-level menus, so that even after a long period of non-use the Fluke 1650B remains intuitive to use. A large display with backlight uses clear symbols and has an exceptionally wide viewing angle for easy and safe readings. There is a PASS/FAIL indication for RCD test results, and a variable RCD current mode for customised settings. An Earth Volt Touchpad detects earth voltages raised above 50V to indicate potentially dangerous situations. A slim probe with test button supplied with the 1652B and 1653B enables initiation of a test without the need to access or reference to the front panel when probing hard to reach points.

The Fluke 1650B is compact, lightweight (less than 1.2 kg) and has a padded neck-strap to free testers’ hands for testing. It is supplied as standard with high quality fused test leads to comply with HSE Guidance note GS38. A durable hard case protects the instrument in tough field conditions. A Zero Adapter ensures easy, reliable and accurate test lead and mains cord compensation. The adapter can be used for all kinds of mains plugs and test accessories like probes and alligator clips.
