Megger VIDAR Vacuum interrupter tester

Description

Rapid Integrity Testing with Advanced Technology Reliability

The Megger VIDAR Vacuum Interrupter Tester stands at the forefront of electrical safety and maintenance solutions, allowing technicians and engineers to swiftly assess the integrity of vacuum interrupters. Frequent in medium and high voltage switching equipment, these crucial components determine reliable and safe power distribution. With the VIDAR, tests are performed quickly, safely, and easily by leveraging the precise correlation between flashover voltage and vacuum chamber integrity. This means users can immediately ascertain the operational readiness of circuit breakers without needing to dismount or deconstruct them, saving valuable time and minimizing the risk of equipment damage. The unit’s intuitive interface ensures results are displayed instantly—green for approved, red for defective—making it friendly for both new and experienced operators alike.

Flexible User-Defined Voltage Range Selection Simplicity

One of the Megger VIDAR’s strongest technical capabilities is its user-defined voltage selection system. The device provides extensive flexibility, letting operators choose the optimal test voltage from a broad spectrum ranging from 10 kV DC to 60 kV DC. The possibility of customizing one voltage output at the factory as per customer specification further enhances adaptability across global testing environments. Thanks to this unique feature, utilities and service centers can conduct routine and commissioning tests on almost every vacuum circuit breaker in their operation. The ability to set appropriate test voltages not only improves test accuracy but also ensures compliance with varying international standards and manufacturers’ recommendations, including IEEE C37.20.3, IEC 62271-1, and IEEE C37.06.

Practical Applications in Power and Industry Maintenance

The practical applications of the Megger VIDAR Vacuum Interrupter Tester reach across medium and high voltage substations, power plants, industrial facilities, and anywhere vacuum circuit breakers are deployed. Field engineers often face the challenge that internal vacuum pressure will eventually degrade—a process that may accelerate rapidly once it begins. Detecting such changes promptly is vital, as a compromised interrupter can lead to unsafe operations, arc flash hazards, and system failures. The VIDAR sharply addresses this need, offering robust, on-site tools to verify the safe operation of vacuum interrupters before equipment is re-energized. Even accumulated external contamination or misalignment of contacts, which may raise operational risks, can be detected or inferred from rigorous testing using this advanced instrument.

Safety-Centric, Dual-Control Operation and Indication

Safety is paramount in any high-voltage testing situation, and the Megger VIDAR is engineered accordingly. Its two-handed control requirement ensures that both hands are engaged before high voltage is applied, drastically reducing the risk of accidental contact. The tester is equipped with a highly visible high-voltage warning lamp to alert operators and bystanders when test voltages are live. In addition, the VIDAR deploys clear, logical indication lamps: green confirms the vacuum chamber passes, red signals a defect, and yellow interrupts to warn of test anomalies or excessive current. The system’s in-built protections—such as limiting transient current to 12 mA and rapid discharge of the high-voltage circuit within 0.3 seconds—demonstrate Megger’s uncompromising safety commitment.

Lightweight, Portable, and Field-Ready Ruggedness

With a rugged yet lightweight design—just 7 kg (15.5 lbs) for the instrument alone—the Megger VIDAR shines in both portability and durability. Measuring only 250 x 210 x 125 mm, it’s engineered for efficient transportation and easy handling on-site. The device is supplied in a sturdy transport case, bringing the total weight to 8.4 kg (18.5 lbs) including accessories. Such portability ensures that asset integrity testing can be implemented wherever it’s needed: in the field, on the shop floor, or within maintenance workshops. This high degree of mobility is particularly advantageous for utilities and contractors who routinely service remote substations or rotate equipment through centralized testing facilities.

Global Standard Compliance and Environmental Endurance

The versatility of the VIDAR is matched by its robust compliance with worldwide safety and performance standards. Designed for operation in tough environments, it functions effectively within a wide temperature range—from -10°C to +50°C (14°F to +122°F) during active use, and can be stored or transported from -40°C to +70°C (-40°F to +158°F). It withstands humidity from 5% to 95% RH non-condensing, and is certified to CE standards in accordance with EU directives on Low Voltage (LVD), EMC, and RoHS. Such levels of environmental tolerance and certification ensure reliable operation in extreme field applications and full acceptance in regulated markets worldwide.
