Product brief description
RMV-112D is a high-precision relay designed by DEIF for power system voltage abnormality protection,with core capabilities including:
Double threshold protection:undervoltage(80%-100%)and overvoltage(100%-120%)are independently adjustable
Intelligent contact configuration:Supports customization of normally open/normal closed contacts,adapted to land/ship scenarios
Quick response:fault detection time≤20ms
Product details
1.Protection logic and functions
Voltage monitoring mechanism
Three-phase measurement:
At the same time,Ua,Ub,Uc are monitored,and unbalanced voltage compensation is supported
Threshold setting:
Undervoltage trigger point 80%to 100%rated voltage,overvoltage trigger point 100%to 120%(step length 0.1%)
Action Characteristics
Mode Trigger Condition Output Contact Type
Undervoltage protection Any phase voltage<U<set value Normally closed contact delay disconnection
Overvoltage protection Any phase voltage>U>Set value Normally open contact instantaneously closed
2.System integration capability
Self-locking circuit:
The contact can be locked after the fault is triggered(reset manually or reset off)
Collaborative equipment:
Can form a complete grid protection chain with RMF-112D(frequency protection relay)
Product Overview:RMV-112D
As the basic model of the DEIF power protection product line,RMV-112D provides reliable voltage abnormality protection for generators,transformers and other equipment through flexible contact configuration and high-precision monitoring algorithms,which is especially suitable for the special safety needs of marine power grids.
