MOCOM
Integrated Monitoring System
PDS provides integrated monitoring system, which acquires and evaluates multiple parameters, thus preventing major failures.
Wear and tear on your high voltage rotating machine is inevitable – caused through electrical and mechanical stress as well as the environment in which it operates.
● How can you tell what is going on inside your machine?
● When will your machine deliver substandard performance?
● When will it fail?
The monitoring of rotor and stator insulation systems of rotating machines provides an early indication of the onset of detrimental risk factors that if not corrected through preventive maintenance, can lead to expensive unplanned outages.
Detection of almost any type of problem in the machine at an early stage of development can be achieved with MOCOM monitoring, as well as PD monitoring.
Equipment Composition
MOCOM is an integrated system designed for Motor Condition Monitoring, which provides various information in all aspects such as electrical (power quality) and physical (vibration and temperature) properties, to discover the existence of potential failure due to wearing or bearing problems and etc. Environmental dust and lack of lubrication are common issues that could lead to motor faults. With the aid of MOCOM, the situation could be effectively prevented.
The MOCOM on-line monitoring system is highly modular. A wealth of functions can be added to the main data acquisition unit, and the unit is the gateway to PDS’s distributed wireless vibration and temperature sensor network.
The main data acquisition unit provides sufficient computing power and storage and is prepared to communicate with the PDS CLOUD server.
MOCOM-M / MOCO
M-VT / MOCOM-DC
MOCOM-M
• 3-phase voltage and current
• Active, reactive, and apparent power
• Power factor
• Total harmonic distortion (THD)
• Harmonic analysis
This covers three major parts as power supply, rotor winding, and bearing, as well as other mechanical components. The expert analysis tool, which analyzes the current motor status and identifies the root cause of faults.
In addition, the system provides multiple fault analysis methods and demand management from power information, which can be accessed through smart devices.
MOCOM-VT
The new universal intelligent sensor system is designed to monitor vibration and temperature in critical locations, which :
• are not easily accessible and installation of wiring may be difficult
• have more than one interesting axis for monitoring
• have strong magnetic or electrical fields
• have strong electromagnetic interference that would deteriorate analogue signals
Every sensor module incorporates all physical sensors, a microprocessor and wireless transceiver. The modules intelligently build a network of connections for data transmission, allowing for reliable data transmissions also in industrial environments.
MOCOM-DC
• Wireless repeater
• Environmental monitor
• Auto sensor searching
• Auto reconnection mechanism
One MOCOM-DC can correspond to multiple MOCOM-M and MOCOM-VT for rotating machines with larger capacity. Additional sensors could be added to the system at anytime, for remote monitoring or as a stand- alone unit. Front-end built-in processor in sensor is capable to perform edge computing, which extracts and processes the important data to reduce the loading of data transferring.
MOCOM-DC can be pre-configured for sensor pairing, which enables Auto Sensor Searching function and Auto Reconnection function at every startup or disconnection. Communication distance between MOCOM-DC and others is up to 100 meters, which is suitable for industrial site layout. And MOCOM-DC can monitor ambient temperature to avoid false alarm due to climate change for a more accurate result.
