Catalogue of equipment:
test benches IS-01, IS-03

Purpose and application

Test benches are designed to check up operation of submersible motor's (ESP) switchboard.

Functional capabilities

Test bench IS-01 operates in following modes of chek-up:

• main supply under- and overvoltage
• voltage (current) unbalance
• raised (low) current load
• low "step-up transformer secondary winding immersible cable - submersible motor" insulance

Device allows to adjust smoothly voltage supplied to the switchboard from 0 up to 425 V (separately in each of three phases) and has a source of current with modulating control within the range from 0 to 400 A. Running regime: long-term. Built-in resistance box enables check-up of insulation control system.

Installed resistor box makes possible to check up insulation control equipment.

Dimensions, mm: 350x450x250.
Weight (not more), kg: 36,0.

Main features

Power supply of the test bench: three-phase network (380 V, 50 Hz). Voltage deviation should be within the range of -10%... +10%.

Rated current while testing supply voltage not more than 1.7 A for each phase.

Test bench's rated current in the current transformer probe mode in the 380 V circuit - not more than 3 A.

Range of test bench output voltage change: 0…450 V.

Range of output current changes in the current transformer probe mode:

0...100 А;
0...400 А.

Note: test bench operation time under maximum probe current must not exceed 5 minutes with the following cooling for 20 minutes.

Discrete values of insulation resistance :

500kОм ± 5%;
30 kОм ± 5%.

The test bench supports:

• supply of three-phase voltage (50 Hz) to the tested object within the range 0…450 V
• linear output voltage control through indicator facility
• Possibility for certified instruments to be connected for output voltage control
• output voltage disbalance within the range of ±300%
• supply the tested object with monophase AC (50 Hz) within the range:

0...100 А;
0...400 А.

• monophase AC control through indicator
• simulation of two discrete values of insulation resistance:

500 kОм ± 5%;
30 kОм ± 5%.

Test bench IS-03

Test bench IS-03 is intended for checking-up validity of controllers of switchboards ELEKTON in both laboratory and field environment. The device makes possible to control indications of current data, counting out restarts delays and controller's protection response.
