TDM 45 series is a revolutionary breakthrough in testing and diagnosis of MV cables. The patented concept addresses the utilities increasing need for flexibility in use of test and measuring equipment based on the type of application.
The modular concept allows the engineer to individually set-up the unit based on the type of job that needs to be executed. If e.g. withstand testing on short cable lengths need to be performed then only one module is needed. When part of the task is also to perform a partial discharge diagnosis then an additional module is needed.
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, a withstand test with VLF cosine-rectangular voltage (VLF CR) and PD diagnosis with damped alternating voltage (DAC) is combined in one unit. This allows an efficient and integrated solution for precise inventory of the network infrastructure. The important fact here is that 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. This facilitates reliable decision making.
High Voltage DC Dielectric Test Sets provide the most dependable, portable DC highvoltage sources for checking the quality of electrical power cables, motors, switchgear, insulators, transformers and capacitors.
