Protective relay N series relay
Denkosha Co., Ltd.
About This Product
■Summary
A protective relay is a device that detects faults such as short circuits and ground faults that occur in power lines and power equipment (transformers, motors, etc.) via instrument transformers and current transformers, and detects abnormalities caused by these faults by detecting faults in normal power equipment. It sends a shut-off signal to circuit breakers, isolates the faulty section, and prevents the fault from spreading. +
Features
■High performance
A high-performance digital relay that uses a 16-bit CPU. A type that does not require a control power supply, allowing for timed characteristic selection. Achieves high reliability with self-monitoring function.
■Easy
The enhanced display functions make monitoring and inspection easy. Easy to set. Also, since it can be set over a wide range, sudden changes can be easily accommodated. Sequence checks are easy with forced operation and return functions.
■Complete functions and lineup
There are two types available: fixed type and internal element pull-out type, and the use of a small molded case also makes it smaller and lighter. Double (2a) contact system eliminates the need for an auxiliary relay for alarm contacts. Compliant standards: JEC-2500 JIS C 4602 (some models of overcurrent relays) JIS C 4609 (some models of ground fault direction relays)
■Types of protective relays
Overcurrent relays, overvoltage/undervoltage relays, ground fault overcurrent/overvoltage relays, ground fault directional relays, ratio differential relays, power relays.
