1. General Features
This Relay contains Relay elements of UVR × 1, and is a Digital arithmetic relay
designed and manufactured properly for the protection against UnderVoltage so it is not
just easy to change the operation time and operation voltage, but it can also record and
store fault information thereby greatly enhancing the reliability of the cable line, and the
main characteristics are as follows.
Features
▣ Total arithmetic type UnderVoltage Relay
▣ Variety of timing characteristics : Inverse Time, Definite Time
▣ Duration of maintaining output contact is 0.00 ~ 60.00Sec (0.01Sec Step),
and variable setting is possible.
▣ Set value and measured values are Displayed digitally through LCD Screen.
(4 x 20 LCD Screen)
▣ Enhance reliability with surveillance function at all times
▣ Free selection of frequency Settings according to the rated frequency of the line.
(50 / 60Hz)
▣ Possible to set each of 5 Relay contact output (T/S Output) to 2 modes, and all
of these can be used for Alarms
- contact for Trip(1a), contact for Signal(4a)
▣ Reliability is increased by the operation through output contacts when the Relay is
in abnormal state
▣ Convenient PC Application
- SetGDRSeries : change setting values, verify the measurements, verify Fault
information, display status, Remote Reset
▣ Possible to self-test through manual Trip command(Contact Test)
▣ Maintains thorough security using password input when changing setting values
▣ Various communications supported
- Communication Methods : RS-232C, RS-485C (SCADA communications)
- Supported Protocol : MODBUS
▣ Increased EMC / EMI performance
▣ Applied Standard : Korea Electrical Manufacturers' Cooperative Standard
(KEMC1120)
