Tan Delta System for Enameled Wires

Tan Delta System for Enamelled Wires - Model EW-188 Specially designed for quality control of enamelled wire. The precise measurement of tan delta is very important for the characterisation of hardening state of the enamelled insulation EW-188 can be used for single point measurement as well as determination of bending point. Tan delta and temperature are displayed simultaneously. The curve measurement can be automated on a PC or laptop using suitable software supplied with the instrument Salient Features Digital readout of Tan Delta and Temperature Software based PID temperature control Windows based user-friendly software USB comunication port for PC or laptop connection Multiple graph comparison on screen Suitable for single point and bending point measurement Fast curve plotting Automatic balancing Direct display Technical Specifications Test Voltage: 10 V AC (peak to peak) Test Frequency: 1 KHz Tan Delta Range: 0.001% to 19.99% Tan Delta Resolution: 0.01% Tan Delta Accuracy: ± 1% of the reading ± 1 digit Indication: 3½ digit panel meter Temperature Range: Ambient to 300 Degree C Temperature Resolution: 1 Degree C Temperature Accuracy: ± 1% of the reading Temperature Control: PID, PID Accuracy: ± 1 Degree C Indication: 3½ digit panel meter Controls: Power ON, Zero / Operate Port: USB communication port Software: Windows based data acquisition softwre Safety Standards: IEC 61010-1 Power Supply: 230 V AC, 50Hz Operating Temperature: 0 to 50 Degree C Humidity: 80% RH at 40 Degree C NOTE: PC or laptop is not in the scope of supply

Capacitance & Tan Delta Test Set - Manual Balancing

Electrical properties of insulating systems changes due to age and continuous electrical stress. By measuring electrical properties such as Capacitance and Tan Delta regularly it is possible to ensure the operational reliability of HV insulation systems and to avoid costly breakdowns. This is particularly important for high voltage bushings, power transformers, generator, power capacitors, HT Cables etc. SIVA Capacitance & Tan Delta test set comprises of C & Tan Delta Bridge model MLS 11-D, high voltage power supply model HLS-12 with built in standard capacitor and set of cables. The compact design of the bridge uses the principle of three winding differential transformer on a high permeability u metal core. The bridge is contained in a sturdy metallic housing with u metal lining which shield it from external electromagnetic and electrostatic influences. Built in battery powered null indicator makes the bridge suitable for operation in workshop, factories, high voltage sub-stations, Switch yard etc. The high voltage power supply model HLS-12 is provided with built in standard capacitor
