SALIENT FEATURES :
Adtron’s Feeder & Motor Protection Panel is a very versatile and useful electrical training system. It provides various experiments on Feeder & Motor Protection. The complete system consists of a three phase feeder with bus bar, output line meters, indicating lamps, contactors / relay, protection relay and other necessary accessories for independent study. Necessary non – destructive fault simulations are provided (motor is not provided ). The control panel consists of:
* 3 Phase Feeder with Bus Bar :
A small section of 3 phase cable will be arranged to represent the 11KV feeder connected to bus bar. Bus bars will be mounted on insulators with colour code for identification.
* Output Line :
Output line from bus bar will be taken out to represent input to motor through meters.
* Metering & Inducting Lamps :
i. Voltmeter 0 – 500 V selector switch at input and motor input terminals.
ii. Ammeter 0 – 10 A in one phase of motor input.
iii. Indicators for bus bar & motor input.
* Contactors & Fuses :
Contactors at feeder input, bus bar input, bus bar output, motor input. Operated through 230 V, 50 Hz auxiliary supply. HRC fuse protection for motor.
* Relays :
Panel will be mounted with mP base relay, permanently connected in feeder and motor circuit. The separate relay will be used for:
a. Motor protection by using 01 no. of mP digital type relay giving following protection:
i. Earth fault.
ii. Current balance.
iii. Over current.
iv. Locked rotor.
b. Feeder protection by using 01 no. of mP digital type relay giving following protection:
i. Earth fault.
ii. Over current SC.
iii. Thermal overload.
iv. Inrush protection.
* Fault Simulation :
Fault simulation circuits will be provided for :
a. Motor Circuit:
i. Earth fault.
ii. Current balance.
iii. Locked rotor.
b. Feeder Circuit:
i. Earth fault.
ii. Over current by SC.
iii. Thermal simulation.
* Instruction Manual :
A detailed instructional / operational manual with details and circuit drawing is provided for students and teachers.
