Catalog ID: MIDAS 2881 The MIDAS 2881 is a portable power factor tester for periodic maintenance and inspection of high voltage insulation losses of electrical apparatus, especially in the harsh electrical environments experience in substations and other field locations.Designed for testing at local power-line frequency, the MIDAS automatically measures and records dissipation factor (tan d), power factor (cos F) and all other relevant values of impedances. Damage or changes in the insulation material are detected rapidly and reliably. |
2823REF High-Precision Capacitance and Dissipation Factor Meter
 |
Catalog ID: 2823-REF
The High-Precision Dielectric-Loss Analyzing System 2823-REF is designed for measurement of very low dielectric losses and impedances (Dissipation Factor and Power Factor) of high-voltage apparatus (e.g. extruded insulation on power cables). The instrument works on the principle of a combined bridge-vector-meter and it is capable of analyzing capacitive and inductive loads – especially shunt reactors – with outstanding accuracy and stability certified by a leading metrology institute.The use of optically decoupled connection allows complete galvanic isolation between control room and test field, and guarantees the highest safety level to the personnel. |

Partial Discharge calibrator KAL 9511 is a successor to the popular Tettex 9216. KAL 9511 covers a wide range of applications. |
9510 Partial Discharge Meter Calibrator
 |
Catalog ID: KAL 9510 The KAL 9510 has been designed to fulfill the standard requirements of a PD calibrator. Its wide range (from 1 pC to 50 nC), its small injection capacitor, carefully selected features and intuitive user interface makes the KAL 9510 unique. |
9230 Coupling Capacitor
 |
The Haefely 9230 high voltage capacitor consists of a modular HV capacitor with appropriate coupling impedance fitted in for partial discharge measurements.The high voltage capacitor is a part of the partial discharge measuring circuit. A closed loop for the high frequency PD signals is established between the test object and the coupling capacitor. The PD pulses are then captured by the measuring impedance and brought to the PD detector.
