Conducted RF Immunity khz: The Neutral Directional element can be used either individually for control or alarm by energizing the auxiliary output relays, or as a part of the Neutral Time, or Instantaneous, over-current elements to define the tripping direction. Effortless Retrofit The small and compact enables multiple relays to be mounted side by side on medium voltage panels. For each reclose shot, the relay can be programmed to block any overcurrent element. Trace any setting changes with security audit trail. With several Ethernet and serial port options, and a variety of protocols, the provides advanced and flexible communication selections for new and existing energy management , SCADA, and DCS systems.

The LED indications are color coded to indicate the type of event. This continuous monitoring and early detection of possible issues helps improve system availability by employing predictive maintenance. 35
Multilin 350 – Chess Electric
Grid Jultilin helps enable utilities and industry to effectively manage electricity from the point of generation to the point of consumption, helping to maximize the reliability, efficiency and resiliency of the grid.
The relay is a member of the 3 Series family of Multilin relays.
Control Synchronism Check The Synchrocheck element is used for monitoring the connection of two parts of the circuit by the close of a breaker. This data allows users to proactively schedule regular maintenance work and schedule upgrade activities. Also available with the 305 a 3500 communication port with Ethernet Fiber and Copper. This provides the information required to determine sequence of events which facilitates diagnosis of relay operation.
This cost-effective protective device is used to perform advanced feeder protection, control and monitoring for low, medium and high voltage applications.
The draw-out construction of the device reduces downtime during maintenance and decreases extra wiring needed for relay testing and commissioning. This element verifies that voltages at both sides of the breaker mulltilin within the magnitude, angle and frequency limits usv by the user before closing the breaker, in order to minimize internal damage that could occur due to the voltage difference, both in magnitude and angle.
Neutral Overcurrent The neutral signal is derived as us residual sum of the three phase CTs eliminating the need for an additional ground sensor. Advanced Communications The incorporates the latest communication technologies making it the easiest and the most flexible feeder protection relay for use and integration into new and existing infrastructures. The basic concept of both protocols, PRP and HSR, is to send identical frames over different paths and discard one of the copies in reception, at best.
The robust streamlines user work flow processes and simplifies engineering tasks such as configuration, wiring, testing, commissioning and maintenance. If an error occurs or one of the paths goes down, the frame travelling through that path will not reach its destination, but its copy remains intact and will reach the multikin destination.
PTP enables clock redundancy and reduces wiring and testing.

Multiple records can be stored in the relay at any given time with a maximum length of cycles Oscillography is triggered either by internal signals or an external contact. The also offers enhanced features such as integrated arc flash protection, metering, monitoring and diagnostics, preventative maintenance, advanced communications and security. These diagnostic tests monitor mulilin conditions that could impact muktilin reliability.
Sensitive Ground Overcurrent Sensitive ground protection feature detects ground faults on high impedance grounded systems in order to limit damage to conductors and equipment.
Retrofit Existing Multilin MII Family Devices Traditionally, retrofitting or upgrading an existing relay has been a challenging and time consuming task often requiring re-engineering, panel modifications and re-wiring. Autoreclose Reclose can be initiated externally or from an overcurrent protection.
Cold Load Pick Up Cold Load Pick up allows automatic or manual blocking or raising of trip settings for a period after the breaker has been closed. The diagnostics data enables the user to understand degradation of electronics due to extreme conditions. Electrically isolated front USB communication port A 4 line liquid crystal multilni LCD allows visibility under varied lighting conditions.
This technology ensures high reliability and availability of communication networks by providing redundancy and zero reconfiguration time in the event of a failure. Viewpoint monitoring provides a complete HMI package with the following functionality: Quadrature Voltage ABC phase sequence: Failsafe communications systems are crucial for industries and utilities with critical applications where no recovery time is tolerated.
This cost-effective protective device is used to perform advanced feeder protection, control and monitoring in a draw-out or non draw-out design multioin low, medium and high voltage applications. This protective device is used to perform primary or back-up circuit protection on medium or high voltage feeders or transformers and down stream protection for utility and industrial switchgear.
Make and carry for 0. Once the information is entered, the simplified setup will generate a settings file, provide documentation indicating which settings are enabled, and an explanation of the parameters entered.
The draw out relay with no chassis is also available to order as a spare unit. Password Control With the implementation of the Password Security feature in the relay, extra measures have been multili to ensure unauthorized changes are not made to the relay.
