Built Tough, Ready Anywhere, Always

Durability and adaptability are at the core of the Megger Electromagnetic Impulse Detector’s design ethos, ensuring its performance in the most demanding environments. This robust device is engineered to work under all weather conditions, from scorching heat to freezing cold, and its construction guarantees it survives rough handling and transport. Such resilience is not merely a convenience but a necessity for equipment used in the field, where unforeseen circumstances and challenging terrains are common. The detector’s components, including the amplifier module, sheath coil, and carrying case, are meticulously crafted to withstand the rigors of frequent use and transportation, protecting the sensitive internal electronics from impact and environmental damage. This ruggedness translates directly into a longer operational lifespan and consistent performance, minimizing the need for frequent repairs or replacements. Furthermore, the inclusion of a long-lasting 9-volt battery ensures that the device is ready for use whenever and wherever it’s needed, eliminating concerns about power availability in remote locations. This combination of weather resistance, shock absorption, and extended battery life positions the Electromagnetic Impulse Detector as a truly reliable and ready-to-deploy solution for cable fault localization, making it a dependable partner for field technicians facing unpredictable conditions.

Pinpointing Faults, Direction Clearly Displayed

The Megger Electromagnetic Impulse Detector excels in its primary function: precisely locating faults and indicating their direction. This capability is fundamental to efficient fault isolation, particularly in complex network systems, allowing operators to quickly narrow down the problematic section of a cable. The instrument’s core mechanism involves detecting the electromagnetic fields generated by impulse currents from a surge generator, which are indicative of a fault. The amplifier module, a critical component, receives output signals from either the sheath coil or optional sensors like the surface coil and earth frame. It then amplifies these signals using a unique “stretching circuit,” which enhances the clarity and readability of the fault signal. The amplified output is fed into a zero-center meter, a key feature that not only displays the magnitude of the signal but, more importantly, indicates the direction of the fault. This directional feedback is invaluable, guiding the technician directly towards the fault location rather than relying on trial and error. The continuously variable gain control, ranging from 0 to 10,000, allows operators to fine-tune the amplifier’s sensitivity, adapting it to various cable types and fault conditions. This precise control ensures that even subtle fault signals can be detected and interpreted accurately, making the Electromagnetic Impulse Detector an exceptionally effective tool for swift and accurate fault identification.

Versatility for Diverse Cable Scenarios

Beyond its primary function, the Megger Electromagnetic Impulse Detector offers remarkable versatility, adapting to a wide array of cable fault scenarios. This adaptability is significantly enhanced by its modular design and the availability of optional accessories. Crucially, the detector converts to a voltage gradient tester with an optional earth frame, expanding its utility for different fault-locating methods. This conversion capability allows for the pinpointing of faults on direct-buried cables, where the earth gradient method proves highly effective. When equipped with the optional surface coil, the instrument transforms into a powerful cable route tracer, enabling technicians to accurately map the path of underground cables. This is particularly useful in situations where cable diagrams are unavailable or inaccurate. The three-position mode switch on the front panel further enhances its versatility, offering selectable positions for “IMPULSE AND TRACE” for fault locating and cable route tracing, and “LOW-HIGH EARTH VOLTAGE” settings specifically for the earth gradient method. This comprehensive set of functionalities ensures that the Electromagnetic Impulse Detector can be deployed in a wide range of applications, from localizing faults on cables buried in conduits to tracing the route of direct-buried cables and pinpointing faults in them. Its compatibility with Megger PFL Systems and surge generators from other manufacturers further solidifies its position as a flexible and indispensable tool for any cable fault diagnosis and management team.

Essential Components for Seamless Operation

The Megger Electromagnetic Impulse Detector is composed of several key components that work in concert to deliver its robust fault-finding capabilities. At its core, the system comprises an amplifier module, a sheath coil, and a carrying case. Each component plays a crucial role in the instrument’s overall functionality and user experience. The sheath coil serves as the primary sensor, designed to be placed directly on the surface of the cable under test. Its function is to sense the magnitude and direction of the net electromagnetic field produced by the impulse current from an impulse generator. This highly sensitive coupler is directional, marked with a large arrow that must always be pointed towards the impulse generator to ensure accurate readings. The amplifier module is the brain of the operation, accepting signals from the sheath coil (or optional sensors) and amplifying them, stretching the signal for clear display on the zero-center meter. The carrying case is more than just a container; it’s a protective enclosure that securely houses the amplifier, sheath coil, and surface coil, ensuring their safety during transport and storage. The availability of optional accessories like the surface coil and earth frame further expands the detector’s capabilities, allowing for cable route tracing and pinpointing faults on direct-buried cables. These meticulously designed and integrated components underscore the detector’s efficacy and user-friendliness in the challenging environment of cable fault localization.

Applications Across Diverse Cable Networks

The Megger Electromagnetic Impulse Detector is a versatile tool with a broad spectrum of applications across various cable network configurations. Its primary use is to localize faults on cable buried in conduit, a common scenario in urban and industrial environments where cables are protected within protective pipes. For this application, a thumper (impulse generator) is connected to the cable to provide impulse current surges, which generate momentary electromagnetic fields around the cable, detectable by the sensitive sheath coil. The sheath coil’s directional sensitivity and the amplifier’s display allow the user to readily see the direction of the fault. These measurements are typically made at access points like manholes, cabinets, and pull boxes. Beyond conduits, the detector can also be effectively used to localize faults on both non-buried and direct-buried cables. When used with the optional surface coil, its utility expands significantly to trace cable routes, providing valuable information about the underground layout of cables, which is particularly useful when documentation is scarce. Furthermore, incorporating the optional earth frame enables the detector to pinpoint faults on direct-buried cable with high precision. This is achieved by detecting the resulting voltage gradient in the earth when impulse current leaks through a fault, providing crucial directional and magnitude information. This wide range of applications makes the Electromagnetic Impulse Detector an indispensable asset for comprehensive cable network maintenance and troubleshooting.
