A high current primary injection test system for all forms of high current testing required in a substation. The SPI2000 is a stackable unit that makes it easy to transport. The main unit can test up to 600 A breaker and add boosters to test up to a 2000 A breaker.
Portable Primary Injection Test set, with stackable boosters to get increased output.
The Model SPI2000 is a high current primary injection test system with the flexibility to test a wide variety of devices such as low-voltage power circuit breakers, molded-case circuit breakers equipped with thermal magnetic or electronic trip devices, overcurrent relays, and thermal relays via primary injection.
The SPI2000 is designed to test a wide range of circuit breakers, with ratings up to 2000 A frame size. The unit is fully compliant with NEMA AB-4 test guidelines.


Compact multi-channel digital PD measuring device for medium voltage and high voltage insulation assessment, offering reliability, precision, and flexibility. Flexibility combines with all PD accessories from Megger. Easy to operate, stand-alone, with high modularity.
The ICMneo is a state-of-the-art, stand-alone digital partial discharge (PD) measurement device designed to evaluate the condition of medium and high voltage insulation. Engineered for reliability and precision, it’s suitable for factory acceptance testing, post-repair assessments, and end-of-line quality assurance, as well as online and offline spot testing on site. This battery-operated device features a 7” touchscreen for intuitive operation and supports up to four parallel measurement channels. Its modular design and advanced capabilities make it a versatile solution for measuring any MV/HV asset including bushings, spacers, cable accessories, instrument transformers, distribution transformers, rotating machines, electronic components e.g. IGBTs. By identifying insulation defects at an early stage, the ICMneo helps prevent costly breakdowns, ensures system efficiency, and supports compliance with the latest IEC 60270 standard.

The PAT250 and CertSuite PAT solution are designed to help small businesses and maintenance teams take control of appliance safety with ease and efficiency. The PAT250 provides quick, accurate pass/fail testing for electrical appliances, ensuring they meet safety standards with minimal disruption to your daily operations. Its mobile functionality and intuitive interface mean that trained staff can easily conduct tests without the need for extensive training. This handheld, battery-operated unit is lightweight, rugged and portable, making it convenient to carry around your facility and store when not in use.

Dual-function cable and phase identification system with long-distance accuracy
The DCI3 is the next generation in cable and phase identification, combining both functions in a single, rugged device that delivers precise results in demanding environments. Replacing Megger’s legacy Phase Identification Line (PIL 8) and complementing the Cable Identifier (CI-LCI) range, the DCI3 streamlines workflows, reduces training requirements, and improves safety across utilities, renewable generation, rail, and industrial networks.
The DCI3’s three-phase cable identification mode can save up to an hour per job, while always-grounded phase identification ensures maximum safety for operators. With a range of up to 30 km and flexible clamp options, the DCI3 adapts to the realities of fieldwork – from confined cabinets to large cable cross-sections. Its IP54-rated enclosure provides durability for use in dusty switchyards, light rain, and the everyday wear and tear of outdoor fieldwork.
Key advantages include:
From high-voltage substations to renewable energy sites, the DCI3 delivers speed, safety, and certainty in a single, portable solution – helping teams work smarter and safer.
