Automatic C & Tand Bridge |
|
Model : MLS-11DA(I) & HLS12A - LINE & GENERATED FREQUENCY OPERATED |
| |
Automatic Capacitance & Tan d Test
Set
This set includes Bridge Model:MLS11DA & HV Supply model :HLS12A Line as well
as generated frequency Model , necessary cables & very flexible, user friendly
Visual C++ windows based Software. The test Kit Automatically Suppress the HV
Induction through Automatic ICU.
The use Windows based software makes the
system more flexible easy to handle & accurate Data can be stored, Retrieved and
analyzed at site. Unlimited DATA Storage. Temp correction for the tand 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.
- Indication of Leakage current.
- Data logging with graph of voltage vs Tand toknow the tand gradient & data
analysis for comparison with old results / manufacturer's data.
- Temperature correction as per IEC for
Tand.
- No controls on front panel since it is totally controlled by Laptop. 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 12 KV
Rated Current 100 mA continuous, 200mA short term rated.
Rated Power 2.4 KVA Intermittent.
Output Frequency 50 Hz ( Lines Frequency )
This power capacity is adequate for capacitance up to 50,000 pF
around 10 KV and other capacitances at reduced voltages. Automatic balancing through windows based software in Laptop No need of
microprocessor
based operation. 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 the stray capacitances and separating
it from basic measurement in GST mode.
Indication : 3 ½ Digital Panel Meter.
Standard capacitor : 100pF/12KV built-in.
Input Frequency : From 50 Hz ( lines frequency) , ± 5%.
Power Required : 230 VAC± 10%, 1 phase AC
Safety Features :
