Description

nnnn

The MSIM (Motor Stator Insulation Monitoring) system is designed for measuring

nnnn

and monitoring the motor's stator insulation condition. The MSIM uses the state

nnnn

of the art technologies to measure the leakage current of the motor online,

nnnn

process the measured data in real time to determine the condition of the stator

nnnn

insulation of the motor. Processed data and results can be displayed on the

nnnn

3500/94 Display.

nnnn

The MSIM system includes:

nnnn

• 3 High Sensitivity Current transducers (HSCTs)

nnnn

• 3 HSCT Interface Modules

nnnn

• 2-3 High Voltage Sensors (HVSs)

nnnn

• 2-3 High Voltage Sensor Interface Modules

nnnn

• 1-3 RTD (temperature sensor) Interface Modules

nnnn

• 1 MSIM I/O Module

nnnn

• 13500/82 MSIM Monitor

nnnn

The 3500/82 can accept 3 HSCT, 3 HVS, and 3 temperature inputs. Since the

nnnn

interface modules are capable of driving long field cables, the monitor can be

nnnn

situated in a control or instrumentation room up to 330 meters (1,000 feet) away

nnnn

from the motor or the interface modules.

nnnn

The MSIM is featured with measurement trending by comparing the current

nnnn

measurements to any historical data taken in the last 30 years (if the historical

nnnn

data is available). The time window for comparison is user configurable.

nnnn

The MSIM has seven buffered outputs for diagnostic purposes, HVS, HSCT values

nnnn

and average temperature.
