Automatic C & Tand Bridge |
|
Model : MLS-5A & HLS-5A ( Front Panel Controlled) |
| |
|
Automatic Capacitance & Tan d Test
Set
This set includes Bridge Model:MLS5A & HV
Supply model :HLS5A , Touch-screen
controlled & necessary cables & very flexible,
user friendly Visual C++ windows based
Software. The use of Touch-screen & Windows
based software makes the system more
flexible easy to handle & accurate Data can be
stored, Retrieved and analyzed at site.
Temp correction for the tan delta of object is
automatically done as per IEC. |
|
FEATURES |
 |
- Automatic Measurement of Capacitance & Tand as per the test plan
by
auto-balancing .No need of manual balancing. Automatic voltage
setting
through software.
- Indication of Leakage current.
- Data logging with graph of voltage vs. Tand to know the tand gradient & data
analysis for comparison with old results / manufacturer's data.
- Temperature correction as per IEC for
Tand.
- Controls on front panel , totally controlled by Touch-screen.
Executes all the test
modes/voltage automatically once fed
- On site printout.
- Suitable for extraneous conditions in 400KV switchyard under heavy induction.
- Unlimited Data-storage in Laptop

TECHNICAL SPECIFICATIONS FOR HIGH VOLTAGE POWER SUPPLY |
|
Test Voltage 0 to 5 KV
Rated Current 120mA Continuous & 240mA intermittent.
Rated Power 600VA & 1200VA intermittent .
Output Frequency 50 Hz ( Lines Frequency )
Automatic balancing through windows based software & touch-screen.
No need of manual voltage control.
Automatic selection of seven different modes of operation for measurement of 3
terminal object from windows based software .
1) UST - Ungrounded Specimen test - 3 combinations
This mode is used when the object under test is not grounded. This test
provides most accurate results.
2) GST - Grounded Specimen test
This mode is used when the object under test is permanently grounded. This
test is used more often in outdoor installations, power systems etc.
3) GSTg - Grounded specimen test with guard. 3 combinations.
This mode is used for measuring them stray capacitances and separating
them from basic measurement in GST mode.
Indication : 3 ½ Digital Panel Meter.
Standard capacitor : 100pF/200pF 5KV built-in.
Input Frequency : From 50 Hz ( lines frequency) , ± 5%.
Power Required : 230 VAC ± 10%, 1 phase AC , 50Hz.
Safety Features :
· Zero start control
· Open ground indicating lamp with double grounded connection
· External interlock.
· HT cut off on overload
· HT ON & Supply ON indication.
· All operating controls at earth potential
· Necessary terminals & Sockets for connection to Bridge |
