HD Electric EM Single-Stick Analogue Voltmeter

The HD Electric EM Single-Stick Analogue Voltmeter can be used to measure AC and DC (through 1000Hz AC RMS) voltages from phase-to-ground. This instrument is available in three models with different ranges; please see the table below for further details.

Model Code Model Name Range (kV) Length with Overhead Probe Hotstick Required 
HD-EM-1 HD Electric EM-1 Single-Stick Single-Range Analogue Voltmeter 0-16 28" (71cm) Yes
HD-EM-2 HD Electric EM-2 Single-Stick Single-Range Analogue Voltmeter 0-25 34" (86cm) Yes
HD-EM-3 HD Electric EM-3 Single-Stick Dual-Range Analogue Voltmeter 0-1/0-15 30" (76cm) Yes

Each of the HD Electric EM Single-Stick Analogue Voltmeters can be used on overhead lines and may be adapted, using accessory probes, to conduct measurements on underground systems. The HD Electric EM Single-Stick Analogue Voltmeter consists of one resistive probe with universal spline and a ground lead. The universal spline enables the HD Electric EM Single-Stick Analogue Voltmeter to be mounted onto hotsticks. This instrument is supplied with overhead brass hook contact probes.

The HD Electric EM Single-Stick Analogue Voltmeter’s coil cord is rated 10kV and has a length of 1.7m when retracted and 3.6m when fully extended. Other lengths, as well as a reel with a straight cord (6.7m) rated 15kV, are also available. To prevent damage to the cable at the points of the highest stress, the cord includes strain relief fittings.

Additionally, high-voltage resistors are encapsulated in epoxy in all resistor sticks, thereby limiting maximum current to approximately one milliamp at full rated voltage.

The HD Electric EM Single-Stick Analogue Voltmeter can measure voltages to an accuracy of 3% full scale. Readings are visible via the HD Electric EM Single-Stick Analogue Voltmeter’s easy-to-read, large, 7.6cm meter face with a Lexan protective cover. Multiple scale models reduce the possibility of misreads.

The HD Electric EM Single-Stick Analogue Voltmeter’s rugged construction and virtually maintenance-free design (no batteries required) makes it ideal for heavy field use. The HD Electric EM Single-Stick Analogue Voltmeter is an accurate, easy-to-use and durable phase-to-ground voltage meter.
