Wavecom_logo

The Wavecom TnT+M is the ideal solution for large volume Portable Appliance Testing, having all the functionality of the most advanced Portable Appliance Testers with the benefit of an inbuilt memory to store up to 40,000 tests. The TnT+M can conduct testing of appliances & Residual Current Devices (RCD’s) with speed & portability storing all data that can be up-loaded to the software when convenient. The user can define saved tests by site, location, description, make, model, serial number, asset number, test frequency, type, comments and number of tests. Information can be easily and quickly input into the memory by the included mini keyboard, which is supplied as standard with the TnT+M.

Testing of Electrical Equipment

Many testing personnel have some reservations in testing sensitive, electronic equipment using a 500V DC insulation test. There is a perceived fear of causing internal damage from over voltage. With the introduction on the Wavecom TnT+M Range of appliance testers, these concerns are alleviated.

The Wavecom TnT+M range of electrical portable appliance testers is safe to test electronic equipment as the tests are carried from Active-Neutral (shorted by a relay inside the tester) to Earth. No dangerous voltages pass through in this mode to the internal components of the DUT (Device Under Test). If these tests are done using an Insulation Tester only and the user tests Active to Neutral, this would be a cause of potential damage, this is why the TnT + M product range is far safer to use.

Some changes may be required in certain configurations where fitted surge protection devices (MOV’s) in the DUT may cause a failed test result. Applying 500V in this these situations can cause the surge protection devices to trip, therefore conducting the applied voltage to earth, thus showing a failure of insulation. In these instances the test voltage should be changed to 250V then retest. If DUT still fails, check with the DUT Operators Manual or an electrician. [for details see – ‘Double Insulation Test’ 250/500VDC to change test voltage].

Under these circumstances, it would be difficult for any damage to occur to either the surge protection device or the DUT, as there is insufficient current generated by the TnT+ M appliance tester.

Leakage Test:

If there are any doubts with insulation testing of the equipment, the standard (AS/NZ3760) allows for an alternative test method. A Leakage Test can be performed instead. (The TnT + M Series are designed to perform these tests).

NOTE: 10Amps MAXIMUM Resistive Load only (Standard TNT + M Series units).

A Leakage Test applies power to the Device Under Test (DUT) and measures the imbalance of leakage current from the DUT between the active and neutral conductors. The leakage is tested to the limits specified in the standard and a Pass/Fail result as well as a digital reading is provided to ensure that the user gains as much information as necessary.

Earth Continuity Test:

The TnT+ M conducts earth continuity tests at Approx. 200mA. Continuity tests at higher currents are not required and are not recommended on certain equipment as this can cause severe damage or premature failure to the DUT under test (as per AS/NZ3760).

3 Phase Testing: * (Note Optional Adaptor is Required)

3 Phase appliances can be tested by the TnT +M series appliance testers. This test is carried out by using the adaptor connection socket. As the insulation tests are from Phase to Earth, only a 500V insulation test is required. These adaptors can be made by your electrician or purchased as an accessory. [See ‘Optional Accessories’ for details – when ordering please state plug configuration of 3 phase plug.] Please note: (The TnT+M cannot perform 3 Phase Leakage test. Contact Rapid-Tech Equipment for the appropriate tester)
