вЂ“ Anyone can explain how to collect ABT meter load survey data through RS 485 port? вЂ“ RS 485 is port, DNP is protocol, DNP is a protocol вЂ“ Anyone can explain the difference between DNP and Rs 485 вЂ“ The motor got tripped on 51n but all three-phase currents are equal, the protection on the calculated value of three-phase currents internally by the relay. DNP can be daisy-chained, just use a terminating resistor

вЂ“ DNP is a protocol that can be communicated over RS232 or RS485 serial port. вЂ“ Correct, RS485 RS232 RS422etc is just a standard for serial communication вЂ“ Yes, if supported by the relay manufacturer. вЂ“ If our side is charged and the other side breaker is off in this case I get all three-phase voltage вЂ“ Does the LA inline side shows leakage current? вЂ“ If I cut my end breaker then I get 2 phase voltage only вЂ“ All three-phase to phase voltage is 110 if the line is charged at both ends. вЂ“ What about pt secondary phase to phase voltage? вЂ“ Does the problem solved now? Check the wiring of pt at tb вЂ“ CVT after breaker or before when charging from both ends then what about the load вЂ“ cut the break from remote end charge from our end then check When I cut our end breaker, then I get only 2 ph voltage вЂ“ please check from the remote end voltage вЂ“ May Y phase jumper opened in transmission line? Y ph voltage is near to zero(i.e, y=7 v) How it is possible? In this case, I get only R, B phase voltage from the same line CVT. But I trip the breaker, now the line remains back charge bcz of opposite end connected. вЂ“ When I charge the 132kv line, then I get the all secondary 3phase voltage at the panel TB from line CVT. вЂ“ Can you tell me what is the name of this marked portion? And why it is connected there?

вЂ“ So you have to compare with the values in manual вЂ“ Input ac supply for the kit is 260V For MV, I have less than 60ms for one while 40 ms for the other type. вЂ“ Usually, the higher volts may not affect the timing but will damage the insulation of the coil вЂ“ ac supply for the kit, No for breaker control supply вЂ“ Direct supply from AC source for testing вЂ“ Does variations in input voltage affect breaker timing? ThatвЂ™s why you would have seen that the current is injected for a very short duration. Yes the hotter it has the higher the value. вЂ“ Is circuit breaker contact resistance temperature-dependent вЂ“ led is blinking for this relay (REL670) вЂ“ ItвЂ™s 934 A is showing when I inject only in R phase вЂ“ inject only r phase backside of the relay terminal not on tb вЂ“ CT ratio is OK in the relay when u inject is there any current in IN? вЂ“ Relay is separated from PT CT, I am injecting current from omicron. вЂ“ R u injected or the line is the charge? вЂ“ Star point of relay Input Is correctly wired вЂ“ Normal voltage is injected, And the normal current is injected. вЂ“ Load on the R phase might be more as compared to other phases. вЂ“ Why is current in the R phase so much high on normal voltage

вЂ“ Check IRF alarm contact status to find the reason, It is an internal fault maybe. If it is a diagnostic failure then also it flashes вЂ“ Go to main menu/monitoring/IED status/self-supervision, Check for the faulty hardware module. вЂ“ Now communicated with relay, But the Blinking problem is not fixed вЂ“ Not showing any fault Or warning code, the Only ready LED is Blinking вЂ“ What is the fault code relay is showing?

вЂ“ When you read the data from relay through software what error it is showing? вЂ“ u can also check the error code in the relay

вЂ“ Is the relay restarting again and again? Because it blinks when in test mode вЂ“ relay faulty indiction is going on annunciation. ThatвЂ™s why itвЂ™s not communicating by software, How to fix it вЂ“ On the upper side of Relay Ready LED is Blinking. вЂ“ Can anyone provide the DNP3 protocol standard?
