INCREASED TIME STANDARDS
FOR REPAIR AND MODERNIZATION OF TECHNOLOGICAL CONTROL, AUTOMATIC CONTROL, PROTECTION, SIGNALING, COMPUTER EQUIPMENT, ELECTROAUTOMATICS, TELEMECHANICS AND COMMUNICATIONS EQUIPMENT AND SYSTEMS

AGREED BY: Central Committee of the Trade Union of Power Plant Workers of the Electrical Industry (Resolution No. 23 of October 19, 1988).

A COMMON PART

1. These consolidated time standards for the repair and modernization of technological control equipment and systems, automatic control, protection, alarms, computer technology, electrical automation, telemechanics and communications are designed for typical volumes of work based on differentiated industry time standards given in Appendix 1 to this collection.
2. The application of consolidated standards does not cancel the effect of the current industry standards listed in Appendix 1. The current industry standards, along with the consolidated standards, are used to adjust the consolidated standards in cases where work is performed in volumes that differ from the standard ones for which the consolidated standards are calculated.
3. Integrated time standards are recommended for use at enterprises of the USSR Ministry of Energy to standardize the work of workers and engineers by issuing standardized tasks and orders, with collective forms of organization and remuneration, when calculating the standard number of personnel of departments performing work included in the collection.
4. The development of integrated time standards is based on the following materials:
- instruction of the USSR Ministry of Energy dated November 10, 1987 No. BC-697-14;
- guidelines for standardizing the labor of workers in the repair of control and measuring instruments (standards publishing house, Moscow, 1976);
- guidelines for labor standardization in the energy sector dated 05/05/1976 No. NS-5694;
- current industry, inter-industry and local time standards for the repair of instruments and devices;
- technical and economic analysis and generalization of experience in carrying out repair and adjustment work by specialized enterprises of the Soyuzenergoavtomatika PA, repair enterprises of the Soyuzenergoremont VPO, thermal power plants and other energy enterprises;
- normative and technical documentation for instruments, monitoring and control system devices.
5. Integrated time standards take into account independent completed types of work and contain an enlarged list of basic operations for specific types of work. Detailed lists of technological operations taken into account by enlarged complex time standards are given in the relevant collections of industry time standards (see Appendix 1).
6. Integrated time standards (hereinafter referred to as time standards) are given for groups I, II, III of complexity of repair and maintenance work, as well as maintenance of instruments and devices.
7. The typical scope of work for repair complexity group III includes the following basic technological operations:
a) preliminary defectiveness of the product;
b) cleaning and washing of devices, components and parts;
c) disassembling the product and components into elements;
d) defectiveness of product elements and components;
e) repair of the mechanical part of the product;
f) repair of the electrical part of the product;
g) repair (painting) of the body, chassis of the product;
h) assembly and adjustment of components and the product as a whole;
i) setting up components and the product as a whole;
j) technological tests (bench testing of devices);
k) acceptance tests (passing quality control department);
l) presentation for verification (for measurement systems subject to verification);
m) preparation of acceptance documentation;
o) familiarization and study of technical documentation when mastering the repair of new types of devices.
8. The scope of work performed in complexity groups I and II includes only part of the typical scope of work contained in complexity group III.
9. In addition to basic repair and maintenance work on instruments, devices, monitoring and control systems, time standards take into account:
- time for preparatory and final work and maintenance of the workplace;
- time for receiving, delivering, moving equipment and materials, as well as time for performers to move within the working area of ​​sites, workshops and laboratories;
- time for rest and personal needs within the limits of current standards;
- time to carry out organizational and technical events, including: issued work permits for the brigade in the conditions of operating workshops of energy enterprises, as well as management of work to ensure the execution of work in accordance with the requirements of PTE, PUE, PTB, PRB, PPB and other instructions.
10. When repairing and handing over instruments (measuring instruments) to the customer without presenting them to the state verifier, the coefficient K = 0.95 is applied to the time standards.
11. When performing work on imported equipment being repaired for the first time, as well as domestic equipment manufactured as prototypes (batch), the coefficient K = 1.2 is applied to the time standards.
12. When performing work on existing electrical installations under voltage above 1000 K, the coefficient K = 1.2 is applied to the time standards.
13. The time standards of this collection are established per unit of equipment (device, device, kit, circuits, systems, etc.).
14. Qualification composition and the actual number of performers are established by the responsible work manager in accordance with the current "Unified Tariff and Qualification Directory of Work and Professions of Workers" (issue 1, 2, 9. M. Mashinostroenie, 1985) and the CS of positions of managers, specialists and employees (issue 1 , Economics, 1986)
15. The collection presents the average category of work, despite this, when rationing and determining the level of performers, it is necessary to take into account the presence of engineering labor when performing work in any section and the average for engineering labor in sections is:

01, 07, 03, 08, 09 - 15%
02, 04, 05 - 25¸30%
06 - 35¸40%
10 - 60%
16. Integrated time standards have been developed for the nomenclature, composition and scope of work of final repair products Price List 06/26/19.
If the composition and scope of work differs from those adopted in the Price List and consolidated standards (differences in the condition of equipment, repair technology, etc.), enterprises, on the basis of data from consolidated standards, as well as differentiated standards, can develop and apply local consolidated time standards.
17. When introducing more advanced forms of labor organization, production technology, equipment, tooling or more at enterprises completed projects organizing jobs that provide more high level labor productivity of workers and engineers, local, more progressive time standards are developed and introduced in the prescribed manner.
18. When introducing time standards, the conditions for the production of work in workshops, on production sites and workplaces are given in accordance with the requirements for repair and adjustment work for each type of instruments, devices, monitoring and control systems.
19. Time standards for the repair of instruments and devices given in the collection apply to the repair of equipment in the production conditions of energy enterprises and specialized repair enterprises (centralized repair).

A table is compiled for calculating the time spent on maintenance of instrumentation and automation equipment (Table 15). Table 15 defines the total time spent on daily maintenance, current and major repairs, removal and installation, start-up and commissioning, verification, which are included in the formulas for calculating the number of personnel in the operation and repair departments of the instrumentation and automation service.

In table 15, in columns 5, 8, 11, 14, 17, 20, two numbers are given. The upper number indicates the total time spent, the lower number indicates the level of work required to perform daily maintenance, repair, verification, commissioning and adjustment, removal and installation.

Calculation of the number of electromechanics in the instrumentation and automation department is performed using the formula:

where A I - turnout electricians on duty;

– the total time spent on daily maintenance of the entire fleet of devices (man-minutes), calculated in table 14;

k з = 1.1 – safety factor, taking into account the implementation of unforeseen work not provided for by time standards;

T cm – duration of the work shift.

We take T cm = 480 minutes.

The payroll number of personnel, taking into account all cases of absenteeism provided for by law, is determined by the formula:

where K c is the transition coefficient, or the coefficient of the payroll staff of workers. It is determined by dividing the nominal working time fund (N) by the effective working time fund (E) of one employee per year.

At 41 hours working week these indicators are equal: H = 2075 hours,

E = 1832 hours (with a 15-day regular vacation).

We are hiring one electrician for the Operations Department.

Calculation of the number of electromechanics in the instrumentation and automation repair department is carried out using the formula:

(5)

where is the total time spent on current and major repairs, startup and adjustment, removal and installation, verification (Table 15).

The headcount of the instrumentation and automation service personnel:

We are hiring one electrician for the repair department.

To determine the qualifications of personnel, it is necessary to calculate the total time spent on performing work by category.

Thus, for the operation department, the total time spent on performing work in category II is determined according to Table 15:

Thus, for the operation department, the total time spent on performing work in category III is determined according to Table 15:

Thus, for the operation department, the total time spent on performing work in category IV is determined according to Table 15:

where n – the number of devices whose maintenance is performed by an electromechanic of category II, category III or category IV.

We will determine the number of personnel in the operation department working in categories II, III and IV

For category II:

We are hiring one electrician of the second category.

For III category:

We are hiring one third-class electrician.

For IV category:

We are hiring one IV category electrician.

Since the operation department can hire one electrician, we are hiring one IV category electrician.

For the repair department, the total time spent on performing maintenance work on instrumentation and automation equipment is determined by III, IV, V categories from Table 15.

For 1st category:

For category II:

For III category:

For IV category:

According to category V:

For category VI:

We determine the number of personnel in the repair department working in the corresponding categories.

For 1st category:

For category II:

For III category:

For IV category:

According to category V:

For category VI:

Since the repair department can hire one electrician, we are hiring one electrician of the VI category.
