| Voltage Sensing, Accurate Measurement and Phasing
Ross Engineering Corporation's Hi-Z® High Voltage Voltmeters are excellent for accurate capacitance voltage tap test point measuring, phasing, energized line indication, as well as direct HV line voltage measurement. The VM25 model measures very low current high source impedance voltages in three or more ranges to 25KV. The VM50 and VM100 model measures up to 50KV and 100KV respectively, in four or more ranges. HV input is high impedance, 85 megohms to over 1,000 megohms as required. The meters are partially shielded against stray electrical fields and have a 125KV, 150KV or 300KV basic impulse test level. All the models utilize a large digital or analog meter scale for accurate voltage measurement. Basic accuracy is ±.5% digital and ±3% analog.
Complete Kits include:
- 25KV, 50KV or 100KV Meter with integral line to ground Probe
- Phasing or line to line with additional Probe
- Optional 6ft or 9ft Collapsible Hotsticks
- Voltage source for testing Voltmeters and Probes
- Optional test point contamination indicating Megmeter®
- High voltage cable clamps or hooks
- Heavy duty carrying case
Ross Engineering Corporation's high voltage calibration lab provides high accuracy capability for conducting tough reliability tests on all our high voltage devices including HV Digital Voltmeters. In this facility we also test and calibrate HV Relays, HV Probes, Spark Gaps, our Fiber Optic Systems, and HV Voltage Dividers up to 450KV. Our Calibration capabilities are up to 450KV PK 60Hz, 400KV DC and 400KV 1.2x50uS lightning impulse. For the calibrations to which A2LA accreditation applies, please refer to the laboratory's Calibration Scope of Accreditation which can be viewed at our website at www.rossengineeringcorp.com
