The GMK Ground Mount Kiosk is designed for the

connection and protection of underground cables

for voltage classes up to 38kV.

The kiosk houses an OSM automatic circuit

recloser, an RC controller, an interlocked isolation

and earthing mechanism and cable connection

compartment.

The OSM automatic circuit recloser has been

extensively type tested by independent laboratories

to ensure long life and reliability under the harshest

environmental conditions. It is the only solid di-electric insulated recloser to provide controlled

arc fault venting and independent testing provides

verification of this important safety feature.

The RC controller provides all the protection, data

logging and communications functions. An operator

panel is used to operate the device locally.

A two phase VT located in the main compartment

provides low voltage AC auxiliary supply to the RC

controller.

A manual trip mechanism is located above the

RC controller, and is used to manually open and

isolate the OSM. The mechanism is then rotated

using a lever to connect earth switches to the

Load side of the OSM.

Underground cables enter the kiosk through a

metal plate provided in the base of the cable

connection compartment. Six DIN 400 or ANSI

Taper aromatic epoxy bushings are provided to

terminate the cables onto the Load and Source

side of the OSM automatic circuit recloser. An

earth bar is also located in this compartment for

earth bond connections.

The OSM automatic circuit reclosers incorporatevacuum interrupters insie a soli ielectricpolymer housing enclose insie an arc ventestainless steel tan. This ensures the maximum inlife an reliability with a fully insulate arrangementinsie the long life housing.

Voltage is measure on all six (6) bushings usingcapacitively couple screens. Current is measureon all three (3) phases using current transformers.

The recloser mechanism is operate by three (3)

separate magnetic actuators, one per phase. Thesemagnetic actuators are mechanically interloceto guarantee correct three (3) phase operation.The evice is latche in the close position bymagnetic latching. Each magnetic actuator usesa single coil.

The open an close position of the evice isinicate by a green 0 to inicate the evice isopen an a re I to inicate the evice is close,this can be viewe through the winow next to thecontrol cubicle.

The status of the recloser is also reflecte by amicroswitch connecte to the control electronics.The electronic circuit boar where the microswitchis fitte has no active elements which ramaticallyimproves impulse immunity.

The main circuit bushings are manufacture fromUV stable polymer an have a silicone rubber

Introduction

The RC10 control an communications cubicle isa microprocessor base controller that provies airectional overcurrent, earth fault an sensitiveearth fault relay, auto reclosing relay, instantaneousmetering, event log, eman logger an remoteterminal unit (RTU) for remote control in a singlepacage.

The operator control panel is provie with a largebaclit LCd isplay an eypa to provie localcontrol functions.

The control cubicle has three (3) main moules:

The operator panel moule which proviesthe man machine interface.

The Switchgear Interface Moule (SIM) whichprovies the power supply battery chargeran incorporates the capacitors that proviethe tripping an closing energy to the OSMtan.

The Relay moule which provies the mainmicroprocessor an dSP functionality.

Temperature compensate float charging is

provie to the seale lea aci batteries locatein the RC10 control cubicle.

There is space provie insie the control cubicleto install any communications equipment to beconnecte to the inbuilt RTU or I/O moule.

The equipment has been esigne for the RC10control cubicle to operate over a temperature rangeof -40 to +55C insie the IP65 seale enclosure.

The cubicle is constructe out of power coatestainless steel for a long, maintenance free lifetime.The roof features a ceramic base insulating

REMOTE CONTROL

The RC10 control provides two method to accessthe event logs time and date stamped to a 0.01sec resolution.

The first is method is from the RC LCD display, itprovides critical operations data for the linesmanand includes close/open operations, fault types,

phase and peak level of fault current.

The second is method is by PC upload usingCMS. It provides a full log of all operational historyincluding setting changes, operations and faulthistory.

The fault history logs include 50 cycles of pre-triphistory to allow analysis of the fault propagation.

The Load Profile is logged with a user configuredintegration period of either 1, 5, 10, 15, 30, 60 and120 minutes.

The following parameters are logged separately forboth positive and negative power flow.

Up to 10000 events can be stored in the memorywhich corresponds to a 417 day, 60 minute,integration period.

CMS can be used to upload and plot the data.
