Business owners hiring this service for the first time looks at the testing process in a holistic manner. However, specific testings are conducted on specific appliances or equipment. If you’re a business owner, set your expectations by knowing the following specific tests.
Visual assessment. This assessment is regarded as the initial part of testing. It will check physical problems on appliances’ builds and wiring system. They are the primary culprits in majority of electric-related problems in a work space that endanger employees’ safety. As the most obvious element to check, technicians will first look for exposed wires and other cosmetic elements to that require attention. Results are noted on logs for documentation after completing the testing process.
Polarity testing. This test will verify if the active and neutral parts of the plug end are placed to their respective terminals. Placements according to BS7671 are right hand side for the ‘Live’ cable while the neutral parts are on the left side. Take note that you must face the socket before the determining the right hand part. Technicians will use a polarity tester in verifying the active and neutral’s positions at the socket end. This test is crucial because it also check for potential short circuits, which are often the cause of most fire incidents.
Insulation testing. While some tests are designed to check the live wires, or the conductors where electricity travels from the source to the appliances, insulation test is conducted to verify the insulator or the rubber part of the wire for protection integrity. Wires are made to have their respective insulation resistance that are acceptable for their purpose. Similarly with polarity testing, a special tester called insulation resistance tester is used to generate the reading. Experts conducting the test ensure that their testers possess the reading accuracy as required by Australian Standards.
Earth continuity testing. This electrical test and tag procedure measures the resistance of the grounding system or also known as earthing system. Measurement obtained on this testing describes a conductor’s electrical potential in relation to Earth’s conducting surface. The test measures the resistance on extension and appliance cords utilizing ohmmeter or PAT testers.
Earth resistance testing. Continuity testing measures grounding, but Earth resistance testing concentrates on the resistance presented by combining earthing rods and connection leads. If you’ll observe technicians, they may use several testers to read this resistance measurement. They also met the standards set by authorities for accurate readings.
These are just five crucial testing procedures a test and tag expert will conduct in your facility. Remember to contact an esteemed tag and testing company to ensure you’ll get accurate testing result as required by authorities. Keep your workplace a safe location for your employees while maintaining your license to operate. Book a test and tag expert today as an investment for your business.
