TAC320/WE is a system to perform life and reliability tests of household appliances.
The multitask management of up to 32 stations. In each station it is possible to run an independent test cycle, different to the test cycles running on other stations.
Each station can be connected to appropriate sensors to acquire the desired measurements (voltage, current, power, temperatures, vibrations, torque, RPM, analogic/digital signals, ...).
A typical test comprises of a sequence of phases that are repeated a programmable number of times. In each phase it is possible to set checks on the acquired measurements which activate alarms or bring the test cycle to an end.
Particularly important it’s the possibility to insert in each part of the cycle safety tests (Hi-Pot tests; Insulation resistance test, Leakage Current tests, …) to check the insulation degradation after hours of working.
The test result system is very efficient and allows the storing of all the test results or just the test results associated with the last N cycles before the end or before an interruption due to an alarm.
The system includes an Industrial PC with WINDOWS10 Operating system for the real time management of the test. The test results are transferred to a second remote PC where it is possible to analyse and print the results of past tests or the partial results of actual running tests.
The test result format is compatible with EXCEL.
Special systems are designed to suit Customer requirements. For example, the photo on the right shows a system with a robot that takes a hair dryer and moves it to simulate the typical movements of a hairdresser. Of course, the cycle can be repeated a programmable number of times.
A very innovative function that can be inserted into the system is the following: at precise phases of the life tests, for example every 200/500 hours, it is possible to suspend the life test and run on the motors under test Partial Discharge test using the LT400 Partial Discharge Windings Analyser. The test to be performed is the measure of PDIV (Partial Discharge Inception Voltage). Measurements must be made between the windings and the ground as well as the terminals of the motor being tested. If the value of PDIV detected is lower than the PDIV value acquired in the previous interruption, this means that the product under test has undergone a PERMANENT DEGRADATION of the QUALITY of the INSULATION. This information is very important as it allows to evaluate the life of a product long before a failure occurs and to evaluate the life of different materials and processes used on the same product.
