Page 63: Sigma-Delta Input Module Circuit Description
MiCOM P747 Chapter 3 - Hardware Design The input module consists of the main input board coupled together with two transformer boards. The transformer boards contain the voltage and current transformers, which isolate and scale the analogue input signals delivered by the system transformers. The input board contains the A/D conversion and digital processing circuitry, as well as eight digital isolated inputs (opto-inputs).
Page 64 Chapter 3 - Hardware Design MiCOM P747 Opto-isolated inputs The other function of the input board is to read in the digital inputs. As with the analogue inputs, the digital inputs must be electrically isolated from the power system. This is achieved by means of the 8 on-board optical isolators for connection of up to 8 digital signals.

Page 120: Busbar Protection
Chapter 5 - Protection Functions MiCOM P747 BUSBAR PROTECTION A protection scheme for a power system should cover the whole system against all probable types of fault. Unrestricted forms of line protection, such as overcurrent and distance systems, meet this requirement, but clear faults in the busbar zone only after a time delay.
Page 121: Through Fault Stability
MiCOM P747 Chapter 5 - Protection Functions However, this is difficult to achieve in practice because the CTs can never have identical characteristics. A fault from another zone that causes a high current to pass through is classed as a through fault. In this case the CTs need to be able to cope without saturating.

Page 128: Current Phase Comparison Check
Chapter 5 - Protection Functions MiCOM P747 The circuitry fail element is time delayed by default. This prevents any conflict with the tripping characteristic if there is a genuine busbar fault. If the circuitry fail element picks up, it triggers an alarm. This can be used to block tripping of the zone differential protection elements.
Page 129: Optional Voltage Criteria
MiCOM P747 Chapter 5 - Protection Functions that it is CT saturation and therefore is an external (through) fault which doesn’t need tripping. In the GROUP X DIFF PROTECTION column, you can set the threshold PhComp Thresh. Note: This is a single-phase device and the term ‘phase comparison’ does not have any association with the word ‘phase’ normally used for single-phase and three-phase systems.

Chapter 7 - SCADA Communications MiCOM P747 (due to retries), increasing message error counts, erratic communications, and in the worst case, complete failure to communicate. 3.2.1 EIA(RS)485 BIASING REQUIREMENTS Biasing requires that the signal lines be weakly pulled to a defined voltage level of about 1 V. There should only be one bias point on the bus, which is best situated at the master connection point.
Page 217: Figure 48: Remote Communication Using K-Bus
MiCOM P747 Chapter 7 - SCADA Communications The K-Bus signal is a differential signal and there is no signal ground connection. If a signal ground connection is present in the bus cable then it must be ignored. At no stage should this be connected to the cable's screen or to the product’s chassis.

Chapter 13 - Installation MiCOM P747 HANDLING THE GOODS Our products are of robust construction but require careful treatment before installation on site. This section discusses the requirements for receiving and unpacking the goods, as well as associated considerations regarding product care and personal safety. Caution: Before lifting or moving the equipment you should be familiar with the Safety Information chapter of this manual.
Page 353: Mounting The Device
MiCOM P747 Chapter 13 - Installation MOUNTING THE DEVICE The products are dispatched either individually or as part of a panel or rack assembly. Individual products are normally supplied with an outline diagram showing the dimensions for panel cut-outs and hole centres. The products are designed so the fixing holes in the mounting flanges are only accessible when the access covers are open.
Page 354: Rack Mounting
Chapter 13 - Installation MiCOM P747 Caution: Do not fasten products with pop rivets because this makes them difficult to remove if repair becomes necessary. If the product is mounted on a BS EN60529 IP52 compliant panel, fit a metallic sealing strip between adjoining products (part no GN2044 001) and fit a sealing ring around the complete assembly, according to the following table.
Page 355: Figure 91: Rack Mounting Of Products
MiCOM P747 Chapter 13 - Installation Figure 91: Rack mounting of products Products can be mechanically grouped into single tier (4U) or multi-tier arrangements using the rack frame. This enables schemes using products from different product ranges to be pre-wired together before mounting.
