Fault location with the ETF 3

The 3kV energy separation filter (ETF 3) is specially developed for fault location on symmetrical communication and pilot cables. This article covers the technology and best way to use the ETF 3, as well as field examples of the the system in use.

Sheath testing for fault location

Water ingress caused by damaged cable sheaths is a leading cause of faults in plastic-sheathed cables. Proper cable maintenance through sheath testing can extend the life of the cable by preventing the long term damage caused by water ingress. This article covers best practices and best equipment to use when sheath testing.

Pre-location transient methods

Learn more about the behaviour of transiet waves when a breakdown occurs at a cable fault, and understand how to evaluate and measure these transients for a more efficient fault location process. This article covers both DECAY (voltage decoupling) and ICE (current decoupling)

 

 

Pre-location pulse reflection process

Learn more about the interaction between pre-locaation and pinpointing to minimise fault location time. pre-location methods referrenced include TDR and HV methods. Additionally, this document discusses the values a fault must exhibit to be located by pulse reflection. 

Pre-location ICE method

The four most effective impulse current (ICE) methods for high resistance and intermittent power cable faults are "Direct mode", "Comparison mode", "Differential-comparison mode", Loop-on/Loop-off mode". The following document discusses the the process of each method.

Pre-location with ARM arc reflection technology

Understanding the most common fault types is critical to cable fault location. More than 80% of cable faults are high impedance faults. This document breaks down the properties of the high impedance fault, and discusses the most effective way to deal with them through Arc Reflection (ARM) technologies. 

Fault location on power cables

Gain insight into specialised fault location and pinpointing proceedures for high voltage power lines. Look at the construction of high voltage cables, as well as the methods and practices that are becoming new the standard, such as condition based preventative maintenance. 

Fault location in low voltage networks

Discover key strategies when conducting fault location on low voltage cables. Inluded are typical LV behaviours, advantages and disadvantages of LV testing, different test methods and best practices.
