SCM
Features & Benefits
Continuous monitoring of PD versus performing periodic measurements provide the following benefits:
- PD occurs on an erratic basis and major defects can be missed if not monitored
- Remote viewing of data via standard communication protocols
- More sensitive and comprehensive than TEV, acoustic or other methods

• Commonly monitored operating parameters include ambient temperature and humidity.
• The SCM’s design allows for independent operation (without a connected PC), yet features a wide variety of built-in communication capabilities.
• Communications ports include Ethernet, USB and RS-485 with a standard communication protocol using ModBus. Dry relay contacts are also available to indicate monitor health and alarm conditions.
• SCM's design supports harsh ambient conditions including a wide temperature range, without the need for additional heaters or coolers.
• The SCM provides a full range of advanced noise cancellation capabilities including the elimination of cross coupled signals.
• The included Microsoft WindowsTM based software application allows for SCM configuration, the uploading of stored data and analysis
• By centrally locating the SCM, multiple switchgear sections can be monitored with one SCM.
Design Advantages
The SCM is industry's partial discharge monitor of choice. It can be configured to have up to 60 PD inputs (four PD modules). Each module features fifteen independent (concurrently monitored), highly sensitive, user configurable input channels; delivering the industry’s best signal-to-noise ratio and allowing connection to a wide variety of PD sensors!
