Tech Tips: Twist Guard Test Leads

A successful project comes to a great strategic vision, even the little things or the tiniest details count if you put your job and craftsmanship.

With Fluke, they think what a successful project is because working with professionals who use the products are taken into a “little thing”. Hence, electrical leads and added features make them more versatile, durable, and above all, safer.

The new Fluke TL175 TwistGuard™ Test Leads is the world’s first adjustable length tips designed to be used for CAT II, CAT III, and CAT IV environments. For CAT III and CAT IV higher-hazard conditions, a twist retracts the tips to reduce the possibility of accidental contact with energized surfaces while for CAT II, it extends the tips for better access to hard-to-reach contacts such as within wall outlets. The Fluke TL175 TwistGuard™ shows the correct category rating whether the tips are retracted or extended.

A system for safe testing

Test instruments and accessories used for electrical testing comprise a safety system called the personal protective equipment (PPE). According to the National Fire Protection Association (NFPA) 70E Standard for Electrical Safety in the Workplace, test equipment is an important part of PPE. Each piece of equipment used for testing such as clothing, gloves, and eyewear to digital multimeters and test leads must be designed and approved to work safely in the testing environment.

Test leads and other accessories should make sure that are rated for safe use where you’re working. Leads should maintain its usage category (CAT) rating or as high as the multimeter you are using. If the test leads did not reach the multimeter, you are putting yourself in danger. But in today’s standards, does lead come with the product?

Double-insulated, extra-safe

The Test leads that gathered years ago may not be fitted with the insulation needed for today’s electrical environment. In relation, the test leads would likely suffer from wear and abuse that can damage the insulation such as leads that have been strained in a panel door or kinked due to sharp bends have decreased insulating capability at stress points.

Fluke TwistGuard™ together with the double-insulated WearGurad™ wires can provide a safer advantage. The inner contrasting color shows through if the outer layer of insulation gets nicked or worn means it is time to replace a new set of leads.

The wires which rated at temperatures of -20 °C to 55 °C (-4 °F to 131 °F) are insulated with silicone can withstand high temperatures and remains flexible in the cold and their universal input plugs are compatible with all instruments that accept standard 4 mm shrouded banana plugs. Accessories like the Fluke AC72 Alligator Clips simply slide onto the extended tips. The TL175 test leads also accept threaded accessories, such as 4 mm lantern adapters.

The Fluke engineers planned for another “little thing” which is durability because TwistGuard™ leads have extra-heavy-duty strain relief on both probe end and plug end that tested more than 30,000 bends without failure.

Why insulated tools are important?

For anyone working around electricity, always make your safety a priority. How? One is, be wary about how you are dressed up, make sure to be guarded with safety suits, shoes, glasses, shields, hard hats, gloves, and especially the tools that you carry. And by tools, we mean insulated tools such as screwdrivers, pliers, cutters and other battery-operated tools.

Deenergizing the equipment is your first resort in working with electricity but sometimes it can be so risky especially that energized equipment has unknown energy pathways that may be fed on the equipment you are working on.

How insulated hand tools keep you safe?

High-quality insulated hand tools are duly designed to protect you in hazardous and unforeseen situations such as electric shock or may reduce the possibility of arc faults caused by short circuits.

But first, it is necessary to be familiar with both regular hand tools and insulated tools. The regular ones are mostly coated with rubber over plastic handles while the insulated ones are built with a special combination of materials that blocks potentially hazardous voltages.

According to NFPA 70E (National Fire Protection Association), using insulated tools is required when dealing with electricity beyond 50 V. This move is especially important for electricity-centered businesses as this could not just save an employee’s life but could also free you from additional expenses and liabilities caused by the accident.

Insulated tool certification

A certified insulated tool must pass through with international standards including IEC 60900 and ASTM F1505. They must undergo thorough testing by third-party labs and can withstand hard use, extreme temperatures and even live flame. They also need to achieve a 1000 ac rating so it can be used in a live panel but only if necessary.

Given that, Fluke insulated tools are engineered to reach that level of protection complying with international standards. We do the same line of stringent requirements and testing to our hand tools for safety, reliability, and ergonomics. They are built by CMV steel for superior durability and designed using the most state-of-the-art facilities and advanced techniques in Germany.

Safe and ergonomic

Fluke insulated hand tools are manufactured with best practice to serve the best way possible. They adapt to the hand so as to prevent you from getting motion injuries or fatigue. Our insulated pliers and cutters work with extreme gripping strength and slim enough to be held easier.

Again, if you work around electricity, you need to look for the best options around you for your safety. With Fluke, we got you covered. Visit our website at www.presidium.ph to know more about our products.

Electric Motor Efficiency & Reliability: Real World Conditions

All electrical machines are powered by an electric motor. In fact, a common industrial plant may consume up to 46% of all generated electricity worldwide. That’s nearly half of the energy consumption that we use. Electrical machines are especially critical for industrial processes hence, any machine breakdown may cause a lot of disruption and a lot of money. Ensuring that motors are efficient and operating at their maximum capacity is one of the most important tasks that technicians and engineers deal with every day.

It’s safe to say that efficient use of electricity is mandatory especially for businesses as inefficiency may lead to financial losses. And since electricity is one of the highest consumers of energy in the industry, it has become a primary target for generating savings and maintaining profitability.

The traditional processes of testing machinery used to be costly and difficult to apply in the working process and at times, it might require you to completely shut down the machine which would mean downtime, just to technicians can check the machine. Luckily, electric motor testing tools that provide more accurate results and have easier processes are now available for us to use anytime.

Fluke 438-II Power Quality and Motor Analyzer

Testing tools such as the Fluke 438-II provides a streamlined and cost-effective method for testing motor efficiency while eliminating the need for external mechanical sensors and costly downtime. It provides mechanical measurements (motor rotating speed, torque, and efficiency) by applying proprietary algorithms to electrical waveform signals.

Using modern and advanced testing tools gives technicians the ability to decrease downtime and give them the opportunity to trend motor performance over time. This way, they are able to see the overall system health and performance. With this, you are sure to save a lot of time and energy consumption at a lesser cost.

How to best present thermal inspection results

Designed to communicate results and produce action, Thermal imaging inspection reports detect repair orders or requirements to monitor equipment.

This report usually includes thermal and digital (visible light) images and shows details such as the date and time of inspection, location of potential problems and even work order numbers.

On top of this, thermal inspection reports should present a summary that shows potential problems, locations and the corresponding level of urgency (how critical) the problems or issues are.

While the main purpose of the report is to point out issues, it is still crucial to take note that not everyone who reads the report are as well-versed in thermography.

This brings in the importance of having and using a thermal imaging analysis and reporting software to improve the image and make the results more visible to the untrained eye.

Here are the three easy ways of how experienced thermographers can enhance thermal images:

Adjusting level and span

Thermal images exhibit a hot spot and a cold spot, that may or may not be problematic. With a thermal imaging software, you can easily readjust the level (mid-point) and span (the difference between the minimum and maximum temperatures) of your image to highlight the area of concern.

Choosing the right color palette

Thermal imaging software allows you to change the palette in the camera or in the software. A monochromatic palette like grayscale or amber works great to show subtle differences. On the other hand, high contrast palettes make it easier to quickly find obvious anomalies.

Blending infrared and digital images

If your thermal imager is equipped with a built-in digital camera, it’s advised to set the blend to 100% thermal when you’re scanning the component. As the digital camera will still be capturing the visible image in the background, you can blend the digital and infrared images in the software to highlight any anomalies you want to call attention to in your report.
