590J V2: CT AND FULL PT TESTER

KEY FEATURES:

• Portable and lightweight for testing P.T.s and C.T.s to 0.02% accuracy offline in the field with primary side voltage/current out of service. Both 50Hz and 60Hz versions.
• Tests for C.T. current and phase error from 2.5/5 up to 60,000/5 or 12,000/1.
• Tests P.T. turns ratio and phase error. From 1kV/100V up to 330kV/110V to 500kV/110V under selectable full or no load conditions.
• Full load P.T. test simulates the various application voltage levels and burden conditions as per elements of the IEC 60044-2 standard. User may also customize application test points to suit adopted standards or new requirements.
• Calculates overall C.T. errors under load from admittance measurement on secondary winding. (Does not require expensive primary current injection testing.)
• Calculates offline admittance at 1.6kHz. This can provide a blueprint to be used as reference for future routine live.

C.T. tests with Red Phase Model 505B.
The model 505B carries out live Admittance tests rapidly during normal operation with the primary 50/60Hz current present; Does not interrupt supply.

• Measures the burden of C.T. and P.T. secondary circuits to ensure C.T. and P.T. not overloaded.
• Automatic demagnetization of CT.
• User is able to create their own set of CT injection and burden test points.
• CT batch testing possible on measurement C.T’s.
• Is able to store up to 1000 C.T. and P.T. records each.
• Able to provide intelligent class (pass or fail) results assessment and also provide best class fit determination.
• Able to download results to a USB flash device or PC.
• Provides for excitation of standard and transient protection C.T.s.
• Graphical presentation of excitation curve also available.
