The Network Rail certified RS4 Tier 2 delivers enhanced monitoring and measurement capabilities over the RS4 Tier 3. This compliant solution enables further increased system availability by providing the full insulation resistance (IR) levels and leakage capacitances of individual feeders on rail IT electrical systems up to 690V. 

Tier 2 compliance is achieved by the use of additional system components including Bender Type B current transformers (CT) and Bender COM465IP condition monitor to enable complex individual feeder measurements.

It provides comprehensive data readings and information on cable health to enable operators a clearer overall assessment of the condition of the Signal Power System.
