SHERLOG CRT has been specially designed as a decentralized monitoring system and is primarily used when the measurement points to be monitored are physically remote from one another, as is the case in switching stations or transformer substations.

Installation requires no external components, such as voltage or current sensors, which would need extra mounting. The connection technology used is also geared towards simple, space-saving, low-cost installation, making the system ideal for use in protection cabinets, to mention just one example.

Equipment:

1. 8 or 16 analog inputs with the following options:
   
   8 channel device
     4 x voltage, 4 x current
     8 x voltage
    
   16 channel device
     4 x voltage, 12 x current
     8 x voltage, 8 x current
    12 x voltage, 4 x current
    16 x voltage
   
   
2. Voltage measuring ranges: 0 - 150 V or 0 - 300 V 
3. Nominal current measuring range for 1 A or 5 A protection or measurement transformers
4. Maximum measurable current: 5, 20 or 40 times the rated current
5. Maximum overcurrent: 100 times the rated current for 3 seconds
6. Measuring ranges for auxiliary signals: +/- 10 V or +/- 20 mA
7. Sample rate of the analog inputs 37.5 kHz
8. 16 or 32 separate binary inputs (no common reference point)
9. 4 relay outputs
10. Full galvanic separation of all inputs up to 2,500 V
11. Robust screw-type terminals for direct connection to protection transformers
12. Connection of measurement signals via Combicon screw-type terminals
13. Housing: 19“, 3 U
