Reliable transformer diagnostics are essential for efficient maintenance of ageing energy infrastructure
Dielectric Frequency Response (DFR/FDS) measurement is a technique for general insulation testing and diagnostics. In comparison with standard 50/60 Hz dissipation factor measurements, DFR measurements has many advantages.

Pre-location transient methods
Learn more about the behaviour of transient 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 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.

Pre-location based on impulse reflection methods
The use of T-branches in low voltage networks makes the evaluation of TDR traces considerably more difficult. Only through comparative measurements of fault-free and defective wires can possible results be achieved. The test pulses of the Teleflex are partially reflected at the T-joint with a negative algebraic sign, while test pulses that continue are simultaneously reduced in amplitude. The amount of reflection depends on the impedance in the main line and the continuing line.

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

Power factor testing of surge (lighting) arresters
The purpose of a surge (lighting) arrester is to limit the over voltages that may occur across transformers and other electrical apparatus due either to lightning or switching surges. This guide explains the power factor test procedure of these surge arresters.

PQ influences on telecommunications
When equipment trips offline, telecom customers can lose their service, costing the telecom money every minute the equipment is offline. This paper looks into how power quality testing can prevent this from happening.
