Testing of electrical installations plays a vital role in the electrical industry. Such tests are available in a variety of types, each with a different purpose. Tests that are commonly performed include continuity testing, insulation resistance and ground fault circuit interrupter tests.

Regular testing is important for securing the safety of a home or office. Consult a professional if you’re not sure what tests to perform or need assistance. You can rely on them to ensure that your electrical system meets all safety and code requirements. For Electrical Testing Cheltenham, Visit Blu Fish

Continuity Testing

The test is designed to determine if two points of a circuit are connected electrically. Any circuit should have continuity to allow electricity to flow as it is designed to.

Insulation Resistance

This test type is used to check the insulation in a circuit or device. The insulation resistance between points is measured by the test. Resistance is ideally the highest possible in order to prevent any electricity leakage and fire hazards.

Ground Fault Testing

These tests are used to detect ground faults. Ground faults are situations where power travels in a direction other than the intended one, resulting often in an electric shock. Dangerous situations can be averted with this type of testing.

PAT Testing

The PAT test ensures the safety of portable equipment and appliances. During the test, a qualified electrician will check your devices to see if there are any indications of damage which could cause harm. Fuses, cables and plugs are all examined to make sure they are still in good shape.

In general, you should have electrical appliances examined every year. However, frequency depends on the circumstances. Those in an environment with a high level of risk, for example, might need to have appliances examined more frequently.

How is PAT testing conducted?

To perform a test is quite straightforward. The first step is for an electrician to visually inspect the wires and appliances, looking for damage like exposed parts or cables that are split. If the device passes this visual inspection, the insulation test will be performed. The insulation test measures all parts of an appliance that carry a current.

An earth continuity test takes place last. This test determines if the earthing is sufficient enough to protect against experiencing an electric shock. The tester will then give the all clear for the appliance.
