NEW DEVELOPMENT PKV/M15 IN BASIC MODIFICATION is a portable device that is designed to measure parameters of time of SF6, oil, electromagnetic and vacuum high-voltage circuit breakers up to 220 kV of all types (ABB, AREVA, ALSTOM, SIEMENS, etc.).

PKV/M15 combines the best of its predecessors, taking into account modern high-speed base in a new compact and portable case.

In accordance with instructions of many vacuum and SF6 circuit breakers manufacturers, it is required to control only time parameters during operation. For some models of circuit breakers the speed of contacts movement can be normalized depending on the time of the travel control section passing. The circuit breakers of that type are equipped with a special device (which is included into the kit of spare parts and accessories) to control the travel time for the control section (isolated section) during the dynamic closing and opening. In this case, a special device is connected to the channel of PKV/M15 in basic modification, which automatically determines the travel time for the isolated section.

At some brands of vacuum circuit breakers parameters of moving contacts, insulating traction, contact clamping, contact wear are normalized for static positions of the circuit breaker, and are defined by means of the measuring tool, that is specified in the user manual of the circuit breaker (caliper, ruler, etc.). Control of these parameters by standard means does not cause difficulties during circuit breaker operation, using the instrument PKV/M15 in the basic modification, and it is not necessary to control these parameters in dynamics.

Object diagnostic results are displayed as data with measured and calculated parameters for each cycle operation (when processing the measurement results of complex cycles, the device automatically divides the cycle into simple operations).

The results provide data on time parameters such as circuit breaker make time, circuit breaker closing time, pole closing time, time difference of contacts action, bouncing in time.

One of the significant differences between PKV/M15 and previous models of PKV-group instruments is implementation of additional types of measurement triggering, which take into account various circumstances during diagnostic:

  • Triggering by main contacts closing is a universal way of measurement triggering, which facilitates the work and does not require additional settings (measurement time, signal duration, cycle type, triggering edge).
  • Dry contact (AUX) triggering is one of the most popular modes among the personnel servicing circuit breakers manufactured by TAVRIDA ELECTRIC, where the Closing and Opening time is normalized by dry contact closing.

At the same time, usual measurement triggering modes are as well implemented:

  • Local triggering mode (internal) is used when connecting directly to the electrical circuit of a high-voltage circuit breaker. In this mode, the device switches the available operating test current.
  • Remote triggering mode (external) is used when connecting directly to the electrical circuit of a high-voltage circuit breaker. In this mode, the device waits for the voltage to appear.

PKV/M15 IN BASIC MODIFICATION is equipped with a power control module for control of switching device drive of both direct and alternating current. Power control module allows you to perform simple operations (in order to perform complex cycles consider PKV/M15 IN EXPERT MODIFICATION).

PKV/M15 IN BASIC MODIFICATION is an independent instrument for diagnostic and presentation of obtained numerical data on the display.

Measurement results can be transmitted via Bluetooth to a mobile device (phone, tablet) to a special software (software is currently under development) or to a PC via USB cable to view the graphs using a special cloud server.

Additionally, the device can be operated under the control of a mobile device via Bluetooth.

PKV/M15 is built into an ergonomic case, which facilitates interaction with the instrument. Weight and dimensional parameters (1 kg / 165 x 100 x 60 mm) rightfully allow us to call PKV/M15 a portable measuring instrument.

A built-in battery provides full autonomy. One charge of the device is enough for at least 4 hours of continuous operation.

Non-volatile memory of 32 MB is enough for a complete inspection of substation facilities.

PKV/M15 is available in two versions (BASIC and EXPERT) that differ in measuring transducers and a set of complex cycles for high-voltage circuit breaker control.
