TTS-Temporary Test Switch
Marwell’s TTS-Temporary Test Switch is designed to allow full meter site access of transformer rated meter sites that do not have test switches,including sites with automatic bypass meter sockets. The Marwell TTS (Temporary Test Switch) adapter will temporarily place a test switch into the metering circuit. The meterman will be able to completly test the site using conventional testing equipment in the same manner as his/her normal CT rated meter sites.
CT Jack Family
The NEW Marwell Series 200 CT Jacks provide both CT probe points and fused potential connections.
In July 2000 we introduced the 100 Series of CT-JACKs, basic jacks to help test CT.s that are directly connected to meter sockets without test switches. They are still available.
CT Jack
- Do you have any CT rated automatic bypass sockets?
- Do you have any CT rated meters that are installed without test switches?
- Do you need a convienent method of "probing" the CT circuits?
- Use the Marwell CT Jack, safe, simple, and cost effective.
Safer PSD “COVER ON” Design
Marwell has improved the Portable Safety Disconnect to allow the switch to be thrown with the
meter socket cover in place. Having the cover in place adds a degree of security that is not available
with other PSD’s.
All previous versions of the Portable Safety Disconnects forced the user to “switch-off” with the
meter socket cover open. Elaborate extraction systems were devised to remove the PSD from its
Socket Verifier
Marwell’s MST-100 is a meter socket tester that is designed to test electric meter sockets for proper wiring prior to setting a kWH meter. Improperly wired meter sockets can be potentially dangerous to the meter installer. In addition to detecting short circuits, improper grounding and reverse-feed wiring errors associated with the meter socket, the MST-100 includes an analog meter that displays any current that may be flowing into the load. By following a few simple steps, the meter installer can use the MST-100 as a tool to verify proper wiring of a meter socket.
