Turns Ratio Testing
-
The transformer turns ratio test, or TTR test, confirms that the transformer has the correct ratio of primary turns to secondary turns. Using this test correctly can help to identify tap changer performance, shorted turns, open windings, incorrect winding connections and other faults inside transformers. Megger’s range of TTR testers are robust to withstand the harsh conditions that some transformer testing in. The range includes varying features to simplify and speed up testing as well as 3 phase TTR testers and PT and CT TTR testers.

Ground Testing
-
Ensuring an effective earth system is essential in a telecommunications system, and Megger is expert in earth testing having been there right from the start. These days Megger offers top end systems for design and soil surveys as well as tough easy to use testers for field engineers. We have tried to make the testers self checking as much as we can, to allow you to concentrate on collating and understanding the results.

Primary Injection Test Systems
-
Primary current injection testing is utilised in high current/high voltage scenarios found at large electrical installations such as substations. A large current (between 100A and 20,000A depending on system specifications and test requirements) is injected directly on the primary side of the electrical system such as a circuit breaker. The objective of the test is to identify how the system operates under various levels of current load.

Battery Testing
-
With the increasing dependency of back up systems on battery strings, and the escalating cost of replacing batteries, instrumentation and software systems that can measure, trend and manage the life-cycle of cells is a cost effective option.

Cable Sheath Fault Location
-
Locating cable sheath faults is one of the last steps in cable testing, occurring after you have identified the existence of a cable fault via the identification procedure based on your specific site variables and the type of system you are working on

Photovoltaic
-
For solar panel installations, problems such as insulation resistance degradation or issues with ground/earth continuity can pose a risk to safety as well as efficient operation. Continuous and predictive maintenance is essential to ensure regulatory compliance as well as the prevention of electrical hazards and fire risks, and enables operators to ensure the optimal performance of PV installations.

Low Resistance Or Continuity Testing
-
From Megger, these highly accurate, easy to operate instruments measure resistance with resolution as fine as 0.1 micro-ohm. Digital micro-ohmeters and DLROs measure contact resistance of switch and circuit breakers, aircraft frame bonds, and rail and pipeline bonds just to name a few of the applications. Megger has models available for testing using test currents from 0.5 mA to 200 amps covering a multitude of applications that require precise low-resistance measurements.

Loop Testing
-
Megger loop testers offer both traditional measuring techniques and state of the art “non-RCD Tripping” technology. Use these products to determine the prospective earth fault current, which is the maximum current able to flow in a phase-earth fault in an installation, and also to indicate the prospective short circuit current which is the maximum current able to flow in the event of a phase-neutral fault.

Time Domain Reflectometers
-
Locating high and low impedance faults on paired metallic cables is a crucial yet often difficult task for a telecoms engineer. Megger designs TDRs specifically for the communications industry, which makes each unit a safe, application specific tester that can be used on virtually all communications cable types. The wide range of TDRs makes it easy to choose the tester with the resolution and range you need.
