PAT testing equipment to use


Pat Testing Equipment: Everything You Need to Know [2024]

Organisations that disregard appliance inspection and testing risk having their insurance policies voided and putting lives in danger. 

If a flaw in an appliance develops and is not checked or noticed by a person who is not qualified, the results could be fatal.

Given the significance of PAT testing and the wide range of operational settings and equipment needed, how can you be confident that you are picking the appropriate equipment for the task?

Accessories should be considered early in the selection process, and a unit should ideally have a good selection of easily available accessories for use in various applications.

This article will cover all the information you require about PAT testing equipment.

What Are the Different Types of PAT Testing Equipment?

The appliance is hooked into the PAT tester during the test. The specific process will be determined by the PAT tester being used and the business’s procedures.

The three types of PAT testing equipment are as follows:

Portable Appliance Testers

It is a collection of testing tools assembled into a single box to simply, efficiently, and accurately test appliances and electrical equipment.

By identifying potential safety issues with electrical equipment before they arise, portable appliance testers lower the danger of electrical shock and fires.

Multifunction Testers

MFTs, also known as multifunction testers, are portable tools used to confirm the security of installations in residential, commercial, and industrial environments

To comply with applicable local standards and safety requirements, these installation testers make sure that fixed wire is put securely and correctly.

MFTs are excellent for analysing electrical properties, including loop impedance, earth resistance, and voltage. 

The ability to save and transfer data from the device to a computer or mobile device is provided by many multifunction tests’ extra features, like Bluetooth.

Fixed Installation Testers

With fixed installation testers, unintentional damage is eliminated. Performance and safety are two of the most important requirements for any electrical system. 

The safety of people, electrical systems, and buildings is guaranteed. 

They are protected against electrocution, fire, and other equipment damage by high-quality insulation, a properly functioning grounding system, and active protection.

What Are the Essential Features of PAT Testing Equipment?

PAT testing can be done manually using a variety of conventional test instruments, such as a low-resistance ohmmeter for ground continuity and a high-voltage insulation tester. 

However, it is typically carried out using an automatic tester that runs a series of tests one at a time.

PAT test equipment performs fundamental safety inspections. 

Most can examine the wiring of detachable mains cords and have an earth continuity test, insulation resistance test, and other features. 

Nevertheless, many do not, for instance, contact current or protective conductor current checks, which require supplying mains power to the tested device. 

The most popular kind for businesses is straightforward PASS/FAIL testers that are simple to use and designed for internal PAT testing with little need for result interpretation. 

Advanced PAT testers are primarily intended for individuals with higher ability levels but can provide more information and testing features.

Voltage Detection

Voltage detectors are a fast, inexpensive way to check for live voltage on ac circuits, switches and outlets before working on them.

Electricians and electrical technicians use voltage detectors the most. 

They assist in ensuring that an electrical circuit has been turned off, allowing for safe repairs. 

Voltage detectors also identify or address malfunctioning equipment and wiring issues.

Insulation Resistance Measurement

The resistance measured in Ohm’s by wires, cables, and electrical apparatus is known as insulation resistance. 

Protecting against electric shocks and preventing equipment damage from unintentional discharges are crucial. 

Testing and evaluating the isolation’s state is how the insulation resistance is measured (head and body.)

Maintenance experts have defined the acceptable lower limit for insulation resistance using the one-megohm guideline for many years.

Insulation resistance must be at least one megohm and around one megohm for every 1000 volts of operational voltage.

Earth Continuity Testing

An earth continuity test ensures the effectiveness of those safety measures in the event of a fault. 

The test measures the resistance between a device’s earth point or PowerPoint and the switchboard.

Portable RCD Testers

Detachable RCDs (Residual Current Devices) are included with some appliances. 

An RCD keeps track of the electricity passing through the circuit to which it is connected. 

Suppose the RCD notices any irregularities that could result in the delivery of an electric shock or lethal electrocution. 

In that case, it will promptly cut off power to the circuit to minimise damage.

What Are the Advantages of Using PAT Testing Equipment?

What are the benefits of PAT testing, then? Let’s examine a few of the advantages listed below:

Improved Safety

By doing routine PAT testing, you can greatly lower the risk of electrical accidents, including electrocutions and fires brought on by electrical appliances. 

Although you can never promise there won’t be an accident at work, doing a PAT test will significantly reduce the likelihood of one happening and safeguard your staff from possibly fatal injuries. 

How many employees at your company use a kettle daily? If that kettle breaks down and the problem isn’t noted, there is a very high likelihood that an accident will occur.

Increased Efficiency

The ease of locating electrical appliance malfunctions at work is another advantage. 

Your life will be easier if a problem is caught and fixed right away with any of the equipment you use regularly rather than if you find the problem on your own and the faulty equipment stops the task you’re attempting to do.

Cost Savings

Electrical appliances are not inexpensive to purchase, and if they are constantly breaking down, you will have to spend a lot of cash on replacements.

Hire qualified people with the necessary equipment to perform routine PAT testing of all electrical appliances and to discover and correct any electrical problems. 

You’ll be doing your business and yourself a real favour.

What Are the Limitations of PAT Testing Equipment?

Nevertheless, you must know some PAT testing restrictions before using them.

Limitations of Portable Appliance Testers

PAT testing could be more accurate and is by far its largest drawback. Compared to other device testing methods, it could be more accurate. 

It is because when portable gadgets are tested, they are frequently jostled and moved around, which can lead to problems. 

Also, testing some devices in a setting different from their natural habitat may result in malfunctions.

PAT testing might be costly, which is another drawback. You should invest a lot of money in hardware and software because locating authentic products for testing can be challenging. 

You must also order the testing gadget from a third party if it isn’t offered in a retail location. 

Last but not least, PAT testing can take a while—sometimes days or even weeks—delaying your product launch schedule. Find out more about the cost of a PAT test.

Limitations of Multifunction Testers

It will help if you consider multifunction testers before buying one because they are a crucial component of an electrician’s job.

When purchasing an MFT, experts emphasise performance and safety while avoiding less expensive and subpar choices.

An MFT is a pricey piece of equipment that may run anything from £350 to $1500. 

Many companies sell them for less money, but in our experience, quality is always worth the extra money, and it’s certainly not worth jeopardising your reputation.

We hope that this guide will satisfy your enquiries about PAT Testing Equipment.

We acknowledge the significance of performing quality PAT tests and the requirement for people in charge of safety and compliance to do so as effectively and efficiently as feasible.

Different equipment will be required depending on the PAT testing type, and the number of tests required. Also, spending money on the right PAT testing tools will be important.
