Making Substation Metering More Reliable

“How to streamline daisy-chained substation meters for better connectivity”

Since Multi-Link began serving the utility industry in 1995, we have found that many utilities are still frustrated with the pitfalls of daisy-chained meters at substations and customer billing sites. The most common complaint involving substation metering is unreliable connectivity; that is when one meter fails, none of the other meters downstream in the series can be accessed.

A simple solution to this substation metering problem is to disconnect the RS485 daisy chain between the meters and install an ACP 2.0 Network Switch & Call Router on a single analog/simulated analog phone line at the meter site. The ACP 2.0 connects to the meters via standard RJ11 cabling to external or under-the-glass dial up modems.

The ACP Series 2.0 enables utilities to communicate with substation meters, modems, relays, RTU’s, etc. more efficiently and securely while cutting costs.

By calling into the ACP 2.0 unit, each and every substation meter can be accessed and read individually. In addition to reliable and consistent connectivity, the ACP 2.0 provides a robust layer of security to each substation meter by locking down each port with Security Access Codes. This telephony firewall feature can be also be used with on-site Ethernet equipment for secure out-of-band network access.

The ACP Series 2.0 can access up to nine devices but uses only a single phone line. Three models are available; ACP-300 (3 device ports), ACP-500 (5 device ports), and ACP-900 (9 device ports). The ACP-500 is the most popular.
