IDME Upgrade

• IDME(evolution) is an upgrade path from an IDM to the next generation fault monitoring family from Qualitrol

• IDM T3 and T5 fault recorders can be upgraded to the IDME versions.

• Aim is to upgrade whilst maintaining existing field wiring

Upgrade

Back to Index

IDME Upgrade

• Upgrade from IDM to IDME involves replacing the following boards– CPU board– Analogue board– Digital (event) board– Front panel MMI

• Re-calibration will

be required after the

upgrade

VT/CT Boards and PSU retained

CPU,Digital & Analog boards changed

IDME Upgrade – improve CT performance

For increased linearity and accuracy on current channels a Taehwatran TS16L split core CT can be fitted over the primary conductor and connected to the rear green connector bypassing the internal CT.

The original IDM internal CT can be left in service but not used – no need to touch the original CT cabling

Back to Index

IDME Upgrade – alternative CT replacement

A project will be started to fit an IDM+ CT to an IDM VT / CT board.

This will provide improved CT performance without the need for external split core CTs BUT will require that the CT and VT wiring is disconnected from the rear of the IDM whilst the VT/CT board is modified or replaced.

Some Utilities are OK with this arrangement as they can use test switches to short the CT wiring and can upgrade without the need for a line outage.
