TechTalk: 2019 DistribuTECH
Booth #10342 at DistribuTech (Feb 5-7 in New Orleans). Exciting new Orion and Bitronics products and features!
January 23, 2019
The Bitronics M871 (Single Line, Dual Bus) and M872 (Dual Line, Dual Bus) IEDs provide a complete solution for monitoring and recording in substation applications. They provide a scalable, low-cost distributed disturbance recording solution that meets all three PRC-002 requirements in a single unit and supports peer-to-peer GOOSE messaging for cross-triggering without hard-wired contacts. The M871 and M872 complement relays by providing independent, higher-fidelity waveform capture with two disturbance recording modes and trend recording not typically found even in the most advanced digital relays. They also provide features such as fault location and SCADA communications that can automate a substation where electro-mechanical relays are used. The ability to support multiple physical links and protocols simultaneously allows easy integration in retrofit applications or newer substation automation projects. The M871 and M872 serve as a front-end to SCADA while also providing system-wide access to important substation data. Multi-mode recording and high speed, high accuracy measurements allow analysis of Network faults, reactions of protective devices, dynamic response of the network, long-term trends, revenue readings at interties, substation equipment performance.
The Bitronics M571 and M572 offer a similar function to the M871/M872, but in a fixed, rather than modular design, and with fewer options. The M571 and M572 are available for sale through 2015, but will become obsolete after that. The M871/M872 are available as replacements for automation and recording applications, while the PowerPlex II can be used as an Ethernet transducer where accurate, high-speed measurements are needed, and for direct connect up to 600 V ac line-to-line.

Modular Design
The M871 uses a modular design based on the Compact PCI bus. There are three chassis sizes:
The M872 uses a modular design based on the Compact PCI bus. There are two chassis sizes:
An M871 must have the following modules:
An M872 must the following modules:
The choices of optional modules and their max quantity depend on the chassis size and what module space is available.

This video shows how a Northwest utility uses the Bitronics M871 to captures a fault and provides key information to the utility. Features such as SCADA data, distance-to-fault, disturbance recording, etc., that weren’t present, can be made available from the M87x. Installing the Bitronics M871 to automate the distribution substation is a low-cost option to performing a relay upgrade or installing an expensive fault recorder.
