I. Product Overview
In order to reduce reactive power loss in power system, shunt capacitor
banks are usually used to improve power factor. In practical application, the
accident rate of capacitor compensation device is relatively high, which is
determined by the characteristics of the working state of capacitor device.
Therefore, it is very important to check the capacitor device regularly and find
capacitor defects early to avoid the expansion of the fault.
Capacitors in the capacitor bank are all in parallel in the field, so the leads
need to be removed when workers measure with a general capacitance meter,
which is a heavy workload and easy to cause wiring errors. The newly
developed capacitor and inductance tester of our company can measure a
single capacitor of a group of parallel capacitors without disconnecting the wire,
and can also measure the inductance and current. The wiring is convenient,
the operation is simple, which reduce the workload of the maintenance
personnel and greatly improves the testing efficiency of the site and provides
security for the normal operation of the power grid.
II. Function Features
The instrument can measure the single capacitor of a group of parallel
capacitors without disconnecting the line, which is convenient to test. At
the same time it can also display the measured voltage, current, loss,
capacity, frequency, impedance and other data.
The instrument displays the measured inductance value and also displays
the measured voltage, current, loss, capacity, frequency, impedance and
other data;

7
The instrument can display the current value and display the current
frequency and other data;
△-type and Y-type connection capacitors can also be measured besides
the group of capacitors;
320×240 large-screen liquid crystal display and Chinese menu prompts
makes it easy to operate;
Built-in large-capacity non-volatile memory: Each test option can store
256 sets of data;
Built-in USB controller interface can export instrument memory data,which
makes it easy for report generation;
Built-in high-precision real-time clock function for date and time calibration;
The instrument comes with a high-speed micro thermal printer to print
measurement and historical data;
Function of test power supply over-current protection can ensure the
instrument will not be damaged when the power supply outputs short
circuit.

6.2. Instrument Operation
After the instrument is well connected to the power line in accordance with
the requirement, turn on the power switch ,and the LCD will display the main
menu which is shown in the following figure.
6.2.1 Capacitance Test
In the interface of Main Menu , press the key < SEL > ,<↑> or<↓> key, and
select the option of Test, then press < OK > to enter the Test Options
interface; When conducting capacitance test, it is necessary to set test
parameters first. Select 1.Test SET to enter the Trial Parameter Setting
interface:

11
Among them: Test Power - refers to the test power supply provided for the test
inside the instrument.Automatic voltage output or manual voltage regulation
(4V, 20V, 120V) output can be selected.
Connection—It means that the capacitor banks with Delta, Y and
single-phase connections can be selected, when the capacitance is tested.
Note: This setting is invalid when measuring inductance or current;
Vol. Level—refers to the nominal voltage level of the test object, used to
calculate the rated capacity of the sample;
Trial No.—refers to the number used to distinguish different tested items or
equipment to facilitate query and technical management in the history.
In the Testing Capacitance interface, press the key <SEL> to select the

12
function options: Test, Stop, Save or Disp; press the key <↑>，<↓> to modify
the phase of current capacitor under test (ab_bc_ca), while the single-phase
