What are the Different Types of PAT Testers?
PAT testing equipment has various levels of functionality. Basic PASS/FAIL kits are very easy to use and relatively inexpensive. They are the preferred choice for a range of businesses, clearly indicating whether an item of electrical equipment has passed or failed. Mains-powered testers require connection to an electrical supply. However, the self-contained battery versions are ideal for large workplaces due to their portability and ease of use. They commonly feature basic light systems that indicate whether electrical items have passed or failed the test.
Basic PAT testing equipment also allows for the establishment of:
- Earth continuity
- Insulation resistance
- Polarity
Basic PAT testers don't display the complete set of electrical test results, and neither do they allow for test configuration or data storage. However, they are often the best choice for obtaining electrical test results quickly and easily.
Advanced PAT testing kits offer the following types of functionality:
- Portable RCD lead testing
- Adjustable PASS test limits
- Substitute and mains powered leakage testing
- Fuse testing
- Lead polarity testing
While a 500V insulation test voltage is typical and suitable for a number of appliances, many PAT testers now include the option of a 250V insulation resistance test. This is essential for testing sensitive and surge-protected equipment, such as IT hardware.
Advanced PAT testing kits are suitable for users with a high level of technical knowledge and expertise. These advanced systems are particularly well suited to facilities management, as they allow for the recording of the location and test status of equipment and appliances. Some of these systems can also transfer the test results to computers for digital interpretation. Test records can be maintained with PAT software.
What does a pat test consist of?
A regular PAT testing includes a visual inspection and electrical testing of an electrical device, which will comprise the following:
- Checking for power cords or cables that are not correctly connected to their plugs
- Powering down and unplugging devices before testing them
- Testing all removable parts such as batteries or memory modules ensures they work and have no issues that could cause fire hazards. If there’s any damage to these areas, then you should consider replacing the whole unit rather than just repairing it because breakages can happen in the future, and you’ll have to start again.
- Check for any defects or signs of wear that may be dangerous – such as frayed wires
- It is not just the device you need to check but the surrounding area as well – so if a cord is hanging over or near something flammable, then that could also be an issue.
