SMC Prime 600 Dynamic Micro Ohmmeter - 600 Amp
DRM: Dynamic Resistance Measurement - Rather than just displaying a single result in micro Ohm, the Prime 600 can, upon user’s selection, perform a series of measurements very quickly across a fast moving contact, like those found in circuit breakers. The result is in this case a time / resistance graph that describes resistance changes on the measured spot throughout a few milliseconds. While requiring extreme accuracy and ultra fast recording from the Prime 600’s micro processor, this technique provides a very representative evaluation of the contact’s condition without having to open the chamber. This feature, never before found in a micro ohmmeter, provides substantial savings especially in the case of SF6 and vacuum isolated breakers, as opening the chamber of one of these devices for visual inspection is extremely costly.
Dual Ground operation - The Prime 600 features a derived current input that measures the current flowing across the earth circuit when both sides of the measured point are grounded. The measured value is then suppressed from the resistance calculation. This eliminates the need to remove the ground protection (which is unsafe and not always possible) and speeds up the measurement process. The user only needs to attach a current/voltage converting clamp (offered as an option) to one of the grounding cables and connect it to the Prime 600’s derived current input. SMC offers a high quality current clamp, tested and verified for proper Dual Ground operation, among the Prime 600’s optional accessories. For increased safety, the Prime 600 will de-magnetize the connected load at the end of each measurement
Applications
- Circuit breaker contact resistance measurement according to ANSI C37.09-1979 (5.14), IEC 1208 and IEC 694 (6.4) standards.
- Quick, efficient condition evaluation of arc contacts in SF6 and vacuum insulated circuit breakers.
- Assessment of connection quality in cable attachments, bus bars and any conductive junctures in electrical installations.
- Transformer / motor / turbine winding resistance measurement.
Continuity in switches, earth connections, welding points, fuses, etc. Loose, defective or dirty connections in a power circuit originate high temperature spots compromising the integrity of the entire installation and are potentially harmful for costly electrical equipment and dangerous for surrounding people. The nature and dimensions of these installations impose the need of accurate, high current injection in order to obtain reliable measurements throughout the entire setup.
Pre-defined test modes - The MODE CONFIGURATION screen provides a simple, straightforward access to 5 pre-defined operation modes, including the Dynamic Resistance Measurement mode and a few user preferences. Measurement can be done in the traditional way or by having the Prime 600 follow you through a sequence of different test spots. Just touch the desired mode on the screen, rotate the encoder to adjust your current and press it to start. The Prime 600 will prompt you with a confirmation message if it detects possible mistakes in your connections. Once the measurement is finished, it will de-magnetize the tested device, too, for your safety. You can produce a printout of your test instantaneously or just save it in permanent memory. The PrimeSync utility will allow you to group tests in a nice report that can be exported to common office formats in your Windows PC.
