Answer / manish joshi

1. RTD's: Resistance temperature Detectors : used to
measure the winding temperature , PT-100 is used in RTD and
normally 6Nos can be used

2. BTD's: Used to measure the bearing Temperature rise.
Normally 1pc/Bearing

3. DTT's : Dial type thermometeres with contacts/without
contacts alarm trip

4. Space Heater: Used to remove moisture when motor starts
after a very long time where moisure is present in the
surroundings. ratings 240 V 1Ph.

5. SPM Nipples: for vibration monitoring

6. Seperate terminal box for space heater.

Answer / pramod_wank

The answer of manish joshi is correct some correction as follows
1. RTD's: Resistance temperature Detectors : used to
measure the winding temperature , PT-100(2mA) is used in RTD
and
normally 6Nos can be used(In each winding 2nos RTD)

2. BTD's: Used to measure the bearing Temperature rise.
Normally 1pc/Bearing (In each side 2RTD used Drive side end
(BE) & non drive side end(NDE))the total 4RTD required

3. DTT's : Dial type thermometeres with contacts/without
contacts alarm trip.(DTT normally used for drive side end &
non Drive side end at max 250v,5A)

4. Space Heater: Used to remove moisture when motor starts
after a very long time where moisure is present in the
surroundings. ratings 240 V 1Ph.

5. SPM Nipples: for vibration monitoring (for drive & Non
Drive Side end)

6.Seperate terminal box for space heater(1ph,240v,300w).

7.Greasing Nipple for Drive & Non drive End.

8.Vibrating Sensor at drive side.

9.Main Terminal box to coonect the supply 415V AC.

10 Neutral terminal Box if required

11.Lifting Hook to lift the motor

12.Earting Bolt as per your electrical system.

This is about the recent problem that we have faced in our project site. We have 6/7.5 MVA. 66/11kV three phase star - star power transformer. The neutral was solidly connected to the earthing mat. But because of high resistance of earthing mat (130 ohm on LV and 180 ohm on HV), one day LV side neutral earthing conductor melted and we had a huge damage. Can any one plz tell me what might happen when we connect power transformer neutral to the earthing mat which has high resistance (>100 ohm ) ?????
