Megger unveils new cable test and diagnosis system

 Megger launches TDS NT – a unique, all-in-one cable testing and diagnosis system. It offers two well-proven wave forms – Very Low Frequency Cosine Rectangular (VLF CR) for withstand testing and Damped AC (DAC) voltage for non-destructive partial discharge diagnosis. These can be used to test cables to international standards such as the IEEE 400.3 and IEC 60502-2. The TDS can also be used for DC tests and sheath tests to the IEC 60229 standard. When paired with a step voltage sensor, it can even be used for precise pinpointing of sheath faults.
Network operators can now get faster and significantly more reliable information about the quality and the condition of their cables. This is made possible thanks to the brand-new 50 Hz slope technology. For the first time, it has become possible to immediately locate faults in underground cables during the actual PD measurement.
With the 50 Hz slope technology for the first time worldwide a withstand test with VLF CR and PD diagnosis with DAC is combined in one unit, Megger claims.
The innovation allows an efficient and integrated solution for precise inventory of the network infrastructure. Most importantly, the PD measurement data, gained with the VLF CR or with the DAC test voltage, can be compared directly with the 50 / 60 Hz network voltage.
TDS NT consists of a multifunctional, compact voltage source and a PD detector. It can be used to test cables according to the international standards (e.g. IEC 60502-2 and IEEE 400.2) with VLF-CR. In addition, a PD diagnosis using the new 50 Hz slope technology can be performed simultaneously with the help of the PD detector. Alternatively, the TDS NT can also be used for PD diagnosis with the proven DAC voltage. In practice, the PD diagnosis has been established as an effective method of measurement. It is especially useful for commissioning testing, as it is the only way to check to reliably check the quality of workmanship of the accessories.
