There are some available multi meters that can measure the capacitance and inductance. And I have used them before. They are easy and convenient to use.
Indeed, typical low cost RLC meters use 1 KHz or 120Hz frequencies. They give you the equivalent series L and R at that frequency.
For 50Hz, a transformer watt-meter set up can be used such as for a short circuit test of transformers.
A lot of information can be got out of more expensive RLC meters in a wide frequency area, the typically measure at 20 Hz up to 200 kHz, in a large number of frequency steps. It can help to make a frequency dependent model.
There is also a lot of measurement technique in chapter 9 of:
Can you elaborate what exactly you want to measure, so that appropriate solution can be discussed. As you can measure the length of an object with a steel rule, vernier caliper or even with more precise optical instruments. It depends what you want to measure.
If you have a sine wave generator and oscilloscope it can de done as well, with a resistor of 1K and look at impedances. Or resonate with a precision polypropylene capacitor and feed with 10K, even a square wave. low impedances feeding with 50 ohm.Multimeters do often not perform well beyond one kHz. These methods do not give a good view on losses.
The medium cost equipment is Hameg or equivalent Chinese types, the higher cost RLC is Agilent.
Is it a coaxial cable, more than two conductors, a power cable, a signal cable?
RLC meters are good for that.
For a coax:use one meter, put the outer side to a square wave, the inner conductor to a 1x oscilloscope probe, calibrate the probe with a 1% 100 pF polypropylene capacitor.
Use a short ciruit test for inductance, resonance with capacitors.but several capacitors in parallel in an arrangement to reduce the inductance of the capacitors and leads to the cable as much as possible.
A typical coax cable has about 0.28 µH/m

a two wire cable rather 0.6µH/m
One has also a capacitance to ground, more difficult to evaluate.
What is the need of high voltage schering bridge? The answer to this question is very simple, for the measurement of small capacitance we need to apply high voltage and high frequency as compare to low voltage which suffers many disadvantages.
U can see the method completely at...the link below. Hope this my help you, bro.
An RLC meter is internally based on a 50 ohm generator of about 1V.
The voltage across the 50 ohm and the load is compared in amplitude and phase.
Starting from that, values are displayed. They use 4-contact (Kelvin type) connectors, to avoid too much effect of contact resistance.
The 50 ohm system means that the highest accuracy is obtained in the range 0.05 ohm and 50000 ohm. In much smaller or much larger impedances, internal voltages below 1mV have to be handled, which reduces the accuracy.
For very low inductances, the position of the wires is very important for the inductance. Two months ago I tried to measure the inductance of a circuit breaker, and it was very difficult, due to the influence of wiring. The reason is that incoming and outgoing wires are not at the same side.
