The paper presents a possible approach to the assessment of the probability of omission the equipment failure, which is controlled by the monitoring system, considering the influence of a human factor as a managing part of a monitoring system on monitoring results. The aim of this paper is a selection and assessment of those components of the human factors that affect the likelihood of failure in modern monitoring systems.

The article presents the results of reciprocating compressors operation under the control of Vibration-Based Diagnostics monitoring systems. dwells upon the issues of usage of reciprocating compressors valves by various vendors and their influence on compressors' vibroactivity. An adequate evaluation of vlbra-activity of piston machines is provided by the Russian regulative database on vibration parameters.
Main differences of Russian and global methods of reciprocating compressors health evaluation, particularly, used frequency range, are presented in the article. It is shown that the approach laid in Russian standards on reciprocating compressors vibration regulations ensures true-to-life assessment of reciprocating compressors assemblies and details condition.
The examples given in the article confirm that the criteria of reciprocating compressors repair correctness assessment should be the machinery health. including its vibroactivity, not just mindless usage of new components purchased from the global brands. Practical examples of operation and monitoring of reciprocating compressors show that Russian developments and products, particularly. scientific-methodological and standards base of Vibration-Based Diagnostics monitoring, reciprocating compressors monitoring systems, reciprocating compressors valves are highly competitive with foreign ones, and sometimes even superior to them in parameters and characteristics, which is a positive factor under the conditions of current economic situation and import substitution policy.

Problems of technical safety and resource-saving in production and transport industries were always topical, but recently, need in their solution became more urgent. This is due both to the growth of volumes and complexity of production, and to a significant decrease in the level of personal responsibility and qualification of personnel of enterprises operating hazardous production facilities.
Besides, there are fundamental reasons of the existing machinery reliability problems at facilities, which mostly comprise hidden nucleation and development of machinery failures, as well as subjective and not timely assessment of machinery condition in real operational processes. That does not allow the personnel to carry out timely and efficient procedures in order to support high technical readiness level of the production. Consequently, the enterprise bear significant operating costs and losses from accidents and downtime of production associated with the sudden failure of process equipment.
The above-listed factors cause an urgent need for general application of automated control systems for safe resource-efficient operation and equipment repair at the hazardous production facilities.

The aim of this work is to study the applicability of an automated stand for testing of machinery monitoring and diagnostics systems.
The work covered determination of algorithms and principles that this stand is based on.
Using the data of requirements and criteria, we developed a stand for automated testing of monitoring and diagnostics systems for pumps and compressors during a facility acceptance test.
The obtained results indicate the feasibility of application of such stands. Applying the stands allows to reduce labor costs while making the testing more full and accurate.

The work aimed at studying into applicability of control methods for partial discharges parameters for induction motors with an operating voltage of 380 V.
The study identified the theoretical background of possibility for the partial discharges inception at low supply voltage. Using existing methods of the partial discharges parameters recording, the measurements were carried out on a large number of low voltage electric motors.
The obtained results confirm the partial discharges presence in the low voltage motors and point to the feasibility of the partial discharges monitoring methods application in insulation of the critical low-voltage motors.

The features of Real-time condition monitoring of machinery and the differences from On-line and Off-line condition monitoring are considered. Taking into account a human factor, the monitoring system model has been reviewed. This model shows that observability of the units state and the entire production complex equipment can be provided by measuring the diagnostic signals (vibration parameters) and rate of their change, which show accurately within scale the generalized units errors and rates of their growth, as well as residual life and its reducing, and the whole complex safety.
Determinate partial ageing functions and their rates, defined by the generalized errors, structural parameters and rates of their growth are offered to be used as variables of the unit’s state. Regularities for petrochemical complex units operation based on a sporadic character of control actions, which are the framework of the monitoring system generalized model, are identified taking into account the human factor.
Technical state of the production complex and correspondingly the risk of its operability loss are offered to be evaluated according to a minimum residual operability and a maximum rate of its loss, observed by the diagnostic and monitoring systems among the units group composing the complex. The required operational speed of the diagnostic and monitoring systems (DMS) is offered to estimate the maximum rate of the petrochemical complex residual operability loss according to the observability criteria of the monitoring theory Conclusions:
Monitoring allows to transfer the equipment and production complexes failures from a “sudden” to a “gradual” category;
Necessity of the failures reduction by ten times and corresponding increase of the equipment run-to-failure requires decrease of the monitoring mistakes to minimum (zero);
Decrease of a statical error and the implementation period reducing up to some months requires development of diagnostic methods and standard techniques invariant to the equipment type diagnostic features formation;
Decrease of a dynamic error requires a significant excess of the monitoring pace over pace of failures development at the production complexes, thus excluding a manual labor by means of automation of all monitoring processes: from parameters measurement and automation of a diagnostic output of information on the equipment state up to its unhampered and timely delivery and presentation to all levels of the production complex control.

The efficiency of malfunction detection for machinery protected by diagnostic and condition monitoring systems is strongly dependent from quality of their tuning, full and objective examination during post-production acceptance tests. However, the task of minimizing the influence of human factor on design quality check-up and tuning process can be successfully solved by automatic test benches.
A test bench provides automation of the most laborsome tasks, such as:
Diagnostic feature calibration in measuring channels;
Metrological check-up for measuring channels;
Expert system check-up, including defect signal formation and registering of the expert system messages;
Automatic formation and printing of a test report, as well as database storage of the results.
