Electric Motor QC Systems
-
Megger Baker Instruments designs and manufactures electric motor test systems for original equipment manufacturers (OEMs) that help ensure their motors, generators and coils meet or exceed the quality expectations OEMs set with their customers. Baker motor quality control (QC) systems include the Baker WinAST automated stator tester, the Baker HV WinAST and the Baker WinTATS traction armature test system. Each incorporates the most effective electric motor test processes into a single automated instrument and can be customized to meet the specific testing needs of a given manufacturer.

Transformer Insulation Testing
-
The primary test methods used to assess the condition of the active insulation components in transformers and bushings, on site, include:1) power factor/tan δ,2) variable frequency power factor/tan δ (1 - 500 Hz)3) dielectric frequency response (DFR) [a dielectric response method], and4) moisture in oil measurements (for transformers).

Cable Locators, Route Tracers And Height Meters
-
CHM cable height meters are easy to use, handheld devices which use ultrasound to determine the height of up to six overhead cables and wires. They are designed to measure cable sag, overhead clearance and cable heights up to 23 m, with separate products dedicated to the power and telecommunications markets. As a safe alternative to telescopic ranging sticks, there is no physical connection to the cables.

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.

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.

Static Electric Motor Analyzers
-
Baker Instruments’ static motor test equipment is the industry-leading suite of products for detecting weaknesses and faults in the insulation systems of electric motors, generators and coils. Employing both low-voltage and high-voltage tests – such as Baker’s signature surge test - these essential troubleshooting and predictive maintenance tools allow maintenance professionals to assess any need to maintain or replace specific motors and generators that support their business. Equally at home in the motor repair shop or on a plant floor, these testers ensure that the electrical condition of your rotating machinery is understood.

Oil Tan Delta Test Set
-
The Oil Tan Delta (OTD) is a laboratory instrument, which measures the Tan Delta, Resistivity and Relative Permittivity of insulating liquids. These tests give a wider picture of the overall quality of the insulating oil, and will indicate if there is any contamination. Megger has developed features of the OTD to ensure that productivity levels within laboratories are maximised. OTD test sets are supplied with sixteen standard test sequences pre-installed, to support a set of international standards.

Circuit Breaker Analysis Systems
-
When a fault such as a short circuit or current overload is detected by a protective relay, a trip impulse is sent to the circuit breaker. The circuit breaker must function as specified and interrupt the current as soon as possible or severe damage may occur. The damage caused by a malfunctioning circuit breaker can often be catastrophic, resulting in significant damage to the electrical system.

Transformer Testing And Monitoring
-
Can detect the symptoms of transformer failure by monitoring the cooling system, load tap changer, dissolved gas, bushing power factor and capacitance, partial discharge, oil levels, pressure, temperatures and more.

VLF Insulation Testing
-
VLF testing uses very low frequencies as part of an AC cable maintenance routine. VLF testers are smaller and more practical than AC testers but output the same amount of power as a 50 Hz mains device. This combination of size and power makes Very Low Frequency cable testing perfect for testing longer sections of cable and apparatus

Low Resistance Ohmmeters
-
Some times know as Ducter testers, these are highly accurate, easy to operate instruments that 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.

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.
