APPLICATION OF MICROPROCESSOR BASED PROTECTIVE RELAY IN POWER SYSTEMS

New Zealand power supply relay protection distance

New Zealand power supply relay protection distance

There is a code of practice that sets out safety distances and that must be followed: New Zealand Electrical Code of Practice for Electrical Safe Distances. This Electrical Code of Practice (Code) sets minimum safe electrical distance requirements for overhead electric line installations and other works associated with the supply of electricity from generating stations to end users. Distance relaying is used to detect faults on long-distance lines, pinpointing not only the fault condition but also measuring the distance between the current sensing mechanism and the fault location in the wire. Our advanced distance protection relays offer field-proven experience with sophisticated algorithms and protection characteristics such as quadrilateral, polygon or mho which are well known for their high performance in complex applications. 'Direct contact' and 'indirect contact' are now designated 'basic protection' and 'fault protection'.

Example of power supply relay protection

Example of power supply relay protection

Protective relays work in conjunction with various electrical protection and control devices, such as Miniature Circuit Breakers (MCBs) and Molded Case Circuit Breakers (MCCBs), to maintain system stability and prevent damage during fault conditions. Protective relays and devices have been developed over 100 years ago to provide "last line" of defense for the electrical systems. They are intended to quickly identify a fault and isolate it so the balance of the system continue to run under normal conditions.

Switching time for UPS power supply in power systems

Switching time for UPS power supply in power systems

These hybrid rotary UPS designs do not have official designations, although one name used by UTL is "double conversion on demand". A hybrid (double conversion on demand) UPS operates as an off-line/standby UPS when power conditions are within a certain preset window. The definition of transfer time, sometimes also called switchover time, says it is the amount of time a UPS will take to switch from utility to battery supply during a mains failure, or from battery to mains when normal power is restored. From plug and receptacle charts and facts about power problems to an overview of various UPS topologies and factors affecting battery life, you'll find a wealth of pertinent resources designed to help you develop the optimum solution. UPS transition time is the time required for the UPS to change from providing AC power derived from the utility (or mains) supply to providing AC power derived from the battery backup.
