SA LEAKAGE CURRENT METER FOR SURGE 30i ARRESTERS

SA 30i the leakage current meter from SCOPE is a State of the Art on-line test system for Residual Life Assessment of Surge Arresters. The instrument measures and directly displays the values of resistive and total leakage current.

The SA 30i can be pre-loaded with the identity (Asset number, make, year, Serial number etc.) and tests conducted on the same ID of the Arresters are saved under its own folder. A trend analysis software, SAdata picks up this data and files them in a similar fashion on a PC. This analysis software enables the user to take a decision to repair/replace the arresters considering safety limits.

SA 30i is designed to work under the hostile electrostatic noise found in live EHV switchyards.

A special low-noise clamp-on CT is used to read leakage current

in the earthing conductor of the Arrester. The field probe is a

non-contact, remote sensing device employed to take the

reference signal from the HV line to the Arrester, for

measurement of phase and system harmonics.

rdThe SA 30i measures 3 harmonic resistive and total leakage

current by compensating the harmonics present in the system

as per IEC 60099-5 B2 or without system harmonic

compensation as per IEC 60099-5 B1

THE MEASUREMENT

qrdq Measures 3 harmonic resistive current with system

harmonic compensation, and the total leakage current.

q In built temperature measurement facility enables calculation of temperature compensated leakage currents.

q Date and time stamp on test data

q Results are displayed on LCD, printed on thermal printer and can be stored in the in-built memory of the instrument. 1000 test records can be stored.

qThe SA 30i is powered by easily available re-chargeable SLA batteries. It works for a day’s testing needs on a single charge.

q The SA 30i is a switchyard compatible instrument. This makes the instrument extremely convenient to use.

The TRM104 is a portable winding resistance meter, designed to work in live EHV switchyards.Winding resistance values of large transformers upto 500 MVA and rotating machines are directly displayed.

The meter contains a special power source for rapid stabilisation of test results.It is possible to measure the resistance of two windings simultaneously.

A backlit 4 line LCD with a user-friendly menu sets up the instrument for the test. Winding resistances and safety messages are also shown on this display.

THE INSTRUMENTA 30V DC, 10 Amp power source, controlled strategically by digital means passes the selected current through the windings.Precision instrumentation amplifiers read voltage developed across the windings and the ohmic values are directly displayed.Use of the classical Kelvin's 4-wire method ensures reliable measurement. Specially designed thermal management ofpower source enables measurement over longer periods, when delta connected generator transformers are tested. The TRM is capable of identifying the interruption of injected current during tap change of OLTC.A beeper alarm during current injection ensures operator safety during measurement.

The meter is protected against the back emf offered by large inductive windings.
