Partial Discharge Testing
DDX 9121b
This unit is built for partial discharge (PD) & radio interference voltage (RIV) testing Traditional PD measurements according to the latest IEC 60270 or RIV measurement, PD under DC and PD cable site location (SL) are covered.
9230 Series
These capacitors are of sturdy and rugged and are for indoor operation. Insulation is reinforced epoxy fiberglass tube filled with oil. The standard design includes a base frame with swivel castors for mobility and upper toroid.
AKV 9310
This unit is designed for simultaneous measurement of high-frequency discharge pulses and also HV test voltage. Built with an internal voltage divider and a dedicated 4 mm output connector for an external low-arm device.
AQS 9110a
The AQS 9110a series of quadripole (measuring impedance) is a fully passive measurement system optimized for use with the DDX series (e.g. DDX 9121b) of partial discharge detectors.
KAL 9510
The high voltage step generator included in this unit allows the use of extremely low injection capacitors (1 pF up to 200 pF) as recommended in the current and proposed future standards..
KAL 9511
The compact PD calibrator is easily controlled by two large buttons. Charge values are displayed on a large display together with battery status and light synchronization indication. An SCS calibration certificate upon request.
Transformer Test Sets
2767
The 2767 automatic current and voltage transformer test set is a modern, fully automatic instrument for fast, accurate measurement of instrument transformer errors. Ideal for Increasingly severe quality control requirements.
3691
The programmable electronic current burden, type 3691 is designed for efficient testing of current instrument transformers. It replaces traditional burdens which are built with passive resistances and inductances.
3695
The voltage burden type 3695 is suitable for standard voltage ratings. Power levels are selectable over a wide range (up to 75 VA) with cos β = 0.1 to 1 at 50 and 60 Hz. High accuracy of 1 % - even with additional external passive burden type 3697 connected
Voltage Dividers & Related Instruments
4861
This is a measuring unit and highly accurate HV divider combining compressed gas and air capacitors. The special active guard controlled design of this divider set results in unmatched, high accuracy.
RM 430
This instrument is used for the measurement and checking of the transformation ratio of voltage dividers. The instrument measures the real transformation ratio taking into consideration external factors.
USG 40
The unit step generator emits recurrent rectangular pulses with rise times of less than 5 ns using a D.C. source 60..300 V. This helps determine the transfer characteristics of voltage dividers and shunts according to IEC 60060-3
Resistance Testing
WA 2293
The WA 2293 is an automatic winding analyser, optimized for three phase power and distribution transformer measurements.
2226a
The digital micro ohmmeter type 2226a is capable of working under challenging resistance measurement scenarios. This unit is designed to measure resistance values in the range of 0.1 μOhm … 20 kOhm.
5478
