Megger's Cable Test Van Sets New Standards

Cable test vans in the new Megger Centrix 2.0 range provide a fast, easy and convenient solution for testing, diagnosis and fault location on underground cables.
The new test vans are an exceptionally useful tool for ensuring that network downtime and consumer minutes lost are kept to an absolute minimum.
Centrix 2.0 vans are equipped with the latest generation of non-destructive cable diagnostic systems and are arranged so that all major functions can be accessed from a comfortable operator position within the vehicle. Megger’s renowned easyGO user interface, in conjunction with a 21.5-inch touch-screen display and a JogDial joystick, ensures intuitive operation for the on-board systems.
A step-by-step operator guide is also provided, and all safety-relevant parameters are automatically monitored in line with current standards. These features are particularly valuable when the van’s test systems are being operated by inexperienced users.
At the heart of the integrated systems on board the Citrix 2.0 cable test vans is a high power TDM 45 diagnostic system which, as well as DC testing up to 80kv, supports three AC test voltage waveforms – VLF sinewave for tan delta diagnosis, monitored withstand testing and partial discharge (PD) diagnosis on short cables; VLF cosine-rectangular (CR) with 50 Hz slope technology for commissioning tests and simultaneous PD diagnosis at high power; and damped AC (DAC) for non-destructive PD diagnosis on aged cables.
The TDM 45 is partnered with a versatile Teleflex® VX time domain reflectometer (TDR) which supports direct TDR operation as well as arc-reflection method (ARM®) techniques for accurate and efficient pre-location of a wide range of fault types. The Teleflex® VX incorporates automatic configuration, automatic cable end measurement and automatic fault location and, for experienced users, also supports full manual control.
Centrix 2.0 cable test vans are provided with lithium-ion batteries and 5 kVA electronic generators, which means they can be used in any location, even if mains power is not available.
All measurements made with the equipment on board the test van are saved automatically in a database, ensuring that information is never lost and is always readily accessible. Results can be printed immediately or saved in the form of PDF file for subsequent retrieval, archiving and reporting.
Megger Centrix 2.0 cable test vans can be supplied in single-phase and three-phase versions. A wide range of customisation options are available to match the vehicles to the specific requirements of individual users.
