ICMflex-Cable testing ,partial discharge detection, loss factor (tanδ) measurements, and PD fault localization.

Description

ICMflex  high voltage instrument family offers inherent operator safety and greatly simplifies distribution class 11KVand 33KV cable testing and other field tasks involving partial discharge and tan delta testing. The instrument is mainly used for on-site testing, but can be used in laboratories and work shops as well.With the unique concept of the ICMflex instruments, the entire acquisition hardware is placed on high voltage potential right at the position where the signals are. Thus, no signal cables are needed, as the instrument is fully self-contained and battery operated. The instrument is fully remote controlled via high speed Bluetooth or fiber optic communication.

It has been designed to simplify the application and to combine different measurement tasks with one instrument. With the unique concept of the ICMflex instruments, the entire acquisition hardware is placed on high voltage potential right at the position where the signals are. Thus, no signal cables are needed, as the instrument is fully self-contained and battery operated. In case that the instruments are used for measurements in an environment with high frequency (HF) disturbance, they can be equipped with a gating input for effective noise reduction. Every ICMflex instrument is fully remote controlled via Bluetooth or fiber optic communication. Using wireless Bluetooth or fiber optic technology the ICMflex tanδ and partial discharge analyzer family increases operator’s safety and greatly simplifies off-line testing and analysis of distribution class cables and rotating machine stator windings.

Option TD

The tan delta analyzer uses an unbalanced bridge formed by internal shunt capacitors, the reference capacitor and the device under test. Here, the ICMflex software shows tanδ, PF, capacitance, voltage, and frequency.

Option PD

With the option PD the ICMflex software offers a meter display according to IEC 60270 and an oscilloscopic display of the partial discharge activity as well as a colored φ-q-n pattern based on the data received via Bluetooth or fiber optic connection. Placing the quadrupole and acquisition unit on high voltage potential greatly improves the sensitivity and avoids any noise pickup on signal cables.

Option LOC

The partial discharge localization option uses high speed (100 Msample) sampling of the PD pulses traveling the cable. Along with the analog bandwidth of 20 MHz this enables precise localization and mapping of the discharge activity along the cable.
