1 Phase and 3 Phase Excitation

Transformer turns ratio is measured by applying line frequency AC voltage to one winding of a transformer and measuring the induced voltage on the corresponding winding.

Reference-application manual is to guide the operator in the appropriate method of making capacitance and dissipation factor/power factor measurements on power apparatus.

Performing high voltage insulation diagnostic tests (power factor, tan delta) on large capacitive specimens.

One of our electricity supply customers had been trying to locate a cable fault using a complex device from another brand - but after an hour and a half of trying, it simply wasn’t accurate enough. Our engineers arrived with the Megger EZ-Thump and, less than ten minutes later, the fault was accurately prelocated. Learn more in this case study.

When a cable fault in a hard-to-access location left our customer running on backup generators, we brought the Megger EZ-Thump in to help. Thanks to its compact size and accurate cable fault location, we were able to have the supplier’s customers back on full power in minimal time. Learn more in this case study.

For a Power Distribution Utility, cable faults are a fact of life. Learn how the Megger EZ-Thump - the “first responder” to a fault on the distribution network - helps to save time and money by quickly locating cable faults. Download the case study below.

It is common practice to evaluate the average insulation condition of high voltage (HV) substation equipment in the field by measuring dielectric losses.

Motor Testing Theory - Reference Guide

Standard guidelines for off-line motor testing for low and medium voltage electric motors.

Information booklet that supports electrical testing and benchmarking, maintenance, and repair of rotating machines.

Find out some of the ways in which motors can degrade, and how Megger’s test equipment can reveal these issues.

Avoid unexpected machine shutdowns, and you can avoid replacing parts which are still in good condition. Learn how vibration diagnostics can help in this five-part series of instructional videos.

When testing motors, it’s important to keep in mind that they are complex electro-mechanical devices with a complex set of failure modes and related diagnostic options.

Corona activity on or near MV/HV insulators and lines has now been recognised as one of the single most destructive mechanisms faced by the Power Industry, demanding a suitable understanding and response.

Transformer testing is a vital practice in maintaining and ensuring the reliability of electrical power systems.
