Megger BALTO Modular DC high current circuit breaker tester

The BALTO Modular DC high current circuit breaker tester was developed to generate, and inject into the circuit, very high and precise DC test currents in order to carry out functional tests on high speed DC circuit breakers. BALTO Modular, is subject to the specifications worked out on the basis of requests from high speed DC circuit breakers’ manufacturers and various railways/train operators and public transport companies, to test DC HS circuit breakers at rolling stock, tramways, etc.


Megger BALTO Compact 4000 DC high current circuit breaker tester

The BALTO Compact 4000 DC high current circuit breaker tester was developed to generate, and inject into the circuit, very high and precise DC test currents in order to carry out functional tests on high speed DC circuit breakers. Useable for up to 4000 A, it meets the challenges of the manufacturers and users of DC high speed circuit breakers, rolling stock, tramways, and primary infrastructure. It is also suitable for on-board maintenance in marine applications.


EGIL200 Circuit breaker analyser

The EGIL200 is the mid-range standard circuit breaker analyser, designed in close cooperation with global industry reference groups, drawing experience from the market leading and hugely successful Megger TM series of circuit breaker analysers. The EGIL200 and its accessories, are prepared for the most demanding field conditions, being the complete toolbox for daily, hassle-free circuit breaker condition assessments.


MOM2 Handheld 200 A micro-ohmmeter

MOM2 has been designed to measure the resistance of circuit breaker contacts, busbar joints, and other high current links. It uses an ultra capacitor to generate its high output current, which is able to store a huge amount of energy compared to conventional capacitors, and can deliver a very high current during discharge thanks to its very low internal resistance. This micro-ohmmeter can be used anywhere to measure a low resistance value with high accuracy. MOM2 use DualGround method.


MVCT VT and CT test set

The MVCT VT and CT test set is a lightweight, portable, and robust unit capable of accurately testing both current and voltage transformers. It weighs less than 20 lb (10Kg) and is capable of performing saturation, ratio, polarity, winding resistance, and insulation tests on current transformers, and can also be used for testing metering and protection class voltage/potential transformers.


SVERKER900 Relay and substation test system

SVERKER900 is the engineer’s ultimate toolbox, addressing the increasing need for three-phase testing in electrical distribution substations, renewable power generation stations, and industrial applications. It has a powerful combination of current and voltage sources and a versatility of measurement possibilities. It is specifically designed for basic, manual three-phase secondary testing of protection devices, and also, you can perform various primary tests.


OTD Oil Tan Delta test set

The OTD Oil Tan Delta is a laboratory instrument designed to measure 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. The design of the cell components also maximise the oil fill rate but minimise turbulence in oil flow.
